    HIGHLY RECOMMEND ! My fiancé purchased my engagement ring and we purchased our wedding bands from here. In addition, we also purchased a cross for our goddaughter's baptism. We worked with Gem who went above and beyond to help us with each purchase and treated us like family. He helped us find exactly what we were looking for! I can't say thank you enough!!

    My fiancé and I walked in to Ultimate Diamond off the street in December 2021, and Billy was kind enough to help us, educate us, and assist us right then and there. I made a follow up appointment in the Spring of 2022 to see specific diamonds, and he again helped me design an amazing custom engagement ring. Fast forward to July 2022, she said yes, and I am a very happy customer. Great customer service and end product!!

    Where’s to begin. From the moment we walked in they made us feel so comfortable. They helped educate myself and my fiancé on rings and diamonds and we’re not pushy sales people. They let us think it over and talk things through over the phone. Kareem, was top notch. He was such a gentleman, such a great business person and his helpfulness was amazing. I cannot thank him, Gem, Diana, and the whole Ultimate team enough. They are an amazing jeweler and I would recommend them to anyone and everyone!

    I worked with John Kirali. He is the best. Professional, first and foremost, but also very personable and friendly, unassuming. I knew very little about rings and he patiently walked me through everything I needed to know. I never once felt pressured or nudged to go for the bigger stone or more elaborate and expensive option. He said it was entirely up to personal preference and what I/we liked and felt comfortable with. I had a specific band and prong style in mind and he worked with me to make it happen. He promised that the ring would be ready by a certain date and he beat that date by a day. This was very helpful because I had to leave town for a long work trip the next day. I can't recommend John enough. Walking through NYC's Diamond District can be intimidating. It feels like you're walking through a bustling bazaar. But when you step into Ultimate Diamond Co, it's like you're temporarily escaping the chaos and entering an oasis of calm. Oh, and you cannot beat their prices. Essentially wholesale prices to the individual customer. Also, the payment process and documentation is all very transparent and very professional with receipts and hard copy printouts for your records. I was able to view the GIA code on my diamond using their microscope when I chose my diamond and again after the ring was completed. 100% confirmation and assurance. There's a reason why Ultimate Diamond Co. is one of the top rated diamond stores in NYC. I would definitely recommend them and send my friends and colleagues there. Thank you, John Kirali!!

    Excellent selections and service! Was looking for a Rolex Submariner 40M (2017) and found the best one here for a terrific price! Avi is your guy!

    Wow! Experience meets professionalism. Above and beyond for their clients! My fiancé purchased my beautiful radiant cut diamond and setting here! Both Jane and Gem made the entire process flawless! Every single question answered timely and in depth! I am IN LOVE with my ring!

  • 5/5 Brian L. 2 years ago on Google
    If I could give this dealer a 6 stars out of 5, I would. My girlfriend and I decided we would walk into a random diamond district store one Saturday afternoon and we happened to (and luckily) find Ultimate Diamond Co. We met with Diana, who from the start was so personable and easy to work with. For context, I am a young dentist working in NYC as a resident in a hospital setting, and my girlfriend and I were looking for engagement rings. We didn't have much experience with diamonds other than knowing the basics about the 4 C's and an idea of the type of ring my girlfriend wanted. So Diana spent a substantial amount of time with us explaining any and everything that should be considered. We had been to another dealer before Ultimate Diamond Co that utilized the classic butter-her-up type of sales tactic, and after showing us rings I couldn't afford, they said, "You're a dentist. You make plenty," not recognizing my position as a resident in a hospital. In contrast, Diana's communication style matched what I look for perfectly. She gave us absolutely no pressure, was transparent, respectful, and clear in her explanations. As you can see from the photo attached, I can be incredibly thorough, using 3.75x magnification loupes that I use for dentistry and my macro photography set-up. To my surprise, Diana welcomed it. Her expertise in the field and years of experience were apparent, and she recognized that all clients should feel confident in their decision about a diamond. My favorite thing about her communication style was that she offered perspectives that we had never considered, even if those perspectives wouldn't lead to the biggest most expensive ring purchase. It was clear that she wanted us to make the most well-informed and educated decision we could possibly make. After two days spent back-to-back with her, my girlfriend and I decided on a ring that we liked and received a price quote. We left the store saying, "We loved Diana, she was so transparent, honest, and helpful." I mentioned to my girlfriend that Diana had said all the right things to earn our trust, and we loved her professionalism and communication style. But the reality was, we didn't know her, and we didn't know if the price was as fair as she made it seem. A couple of days later, we met with a friend of a friend who works in the diamond industry. We showed her all of the price breakdowns, specs, dimensions of the stone, etc that we received from Ultimate Diamond Co. Our friend was honest with us and confirmed that the prices were extremely competitive, since Ultimate Diamond Co is not only a retailer but also a wholesaler and is therefore able to offer clients more competitive prices. They also confirmed that, as Diana had told us, the stone we selected was a "unicorn", and that because of the dimensions, the stone appeared far larger than its actual carat size. Because of our friend's expertise, it validated our trust in Diana, and that evening I put a deposit down on the stone. When we went, we had just missed Diana before she left, so we met with Ronny, Bill, and Danielle. I have to say that I did not expect to feel so familial with the staff when 4 days prior, they were all strangers. They were all so personable and easy-going as well. A week later, I came back to Ultimate and we finalized the setting and the ring. My soon to be fiancee and I cannot recommend Diana and the staff at Ultimate Diamond Co enough - they will show you the attention, the clarity, the honesty, and the pricing you need to make what normally would be a very stressful purchase one of the most enjoyable and confident purchases you'll ever make.

    Amazing experience! I worked with Gem, and he made the process fun and painless. My fiancé absolutely loved the ring I got for her. Gem gave me guidance throughout the process and continued to work with me until I was completely satisfied. Will definitely be back for all my future jewelry needs and would highly recommend to anyone in need of an engagement ring.

    I picked up the 41mm Wimbledon and had a great first watch buying experience thanks to the help of Avi and Valentina. Everyone in the store was very friendly and it was important to everyone working there that you got what you wanted. They were an absolute pleasure to do business with and it will be the first of many, Ultimate Diamond Co is going to be the first place I go when I’m in the market.

    We purchased wedding rings from Brian and got them polished, right before the wedding. Rings were super shiny and looked amazing both in person and in photos. I also got the ring resized once as I prefer to wear tighter, and after resizing, it fitted perfectly. If you are looking for a place where you can get perfect after-purchase services, look no further. Ultimate Diamond knows what is is doing! Also thanks for cleaning my diamond studs (that I worn on the wedding) for free!

    I went to Ultimate Diamond to buy a diamond ring which I promised for my mother after saving my hard earned money. Diana was the person who assisted me all throughout. She is very professional in her job. I have never felt being pressured in anyway. I was fully catered even when I was inquiring at first. She made the whole process extremely easy and relax for me. She even let me inspect the Diamond Ring that I bought under a GIA grade microscope. She really earned my trust as a customer and I will definitely go back to Ultimate Diamond in the future. Thank you for the pleasant experience!

    Our Ultimate Diamond experience was fantastic. Billy was great and walked me through all the particulars of diamonds and engagement rings. No pressure at all. He was very approachable and made a potentially daunting process enjoyable and easy. Diamonds and craftsmanship are top notch and everyone loves the finished product. Will absolutely be back. Thanks again Billy!

    Ultimate diamond is the best! Gem helped my fiancé find the perfect ring. He was able to keep him calm and help him through the process. We then got our wedding bands there as well which Gem did a great job helping us pick out and a fair price. Gem treats you like one of his family. One of my pave diamonds fell out and he replaced it free of charge. He also resized it for no cost. If you’re looking for a reputable spot in the diamond district look no further!

  • 5/5 Nicole C. 1 year ago on Google
    My fiancé and I highly recommend Ultimate Diamond. We had a fantastic experience and could not be happier with the engagement ring we purchased. The whole team is wonderful; we had the pleasure of working most closely with Billy and Danielle. While we considered several jewelers, Ultimate Diamond quickly set themselves apart from the first appointment. We wanted to understand the 4Cs with in-person examples, and Billy patiently walked us through each one and showed us several diamonds to demonstrate the ranges. We were impressed with his willingness to give a solid diamond education (and answer all our questions!) without any commitment to purchase, and that combined with his no-pressure approach sealed the deal. Once we had defined our specific criteria (shape, carat, color), the team found us a handful of diamond "finalists" to choose from - no small feat, as I understand radiant-shaped diamonds are relatively uncommon! Billy's expertise and guidance made the design process easy and fun, and both he and Danielle maintained great communication with us between appointments. On top of all that, pricing was fully transparent and super competitive - we felt we got an excellent deal. I never leave Google reviews, but I had to make an exception in this case. You cannot go wrong working with Ultimate Diamond!

    The entire team went above and beyond. The care and service we received was beyond compare. Amazing experience! Made us feel like family! Worth the trip to NYC for any future purchases.

  • 5/5 Armin P. 9 months ago on Google
    Do your research and then go there and meet with Brian. I believe he enjoys of what he is doing, he spends time and educates about everything you need to know about the diamonds. He is so patient and professional. I would definitely recommend here and would definitely go back again. As a recommendation I think the process of picking up can get better by doing a better quality control to avoid wait time for the customers. If the salesman was responding and available during the pickup this would have created a much more better experience but anyway they’re the best in the all diamond district!

    Would really like to thank Ultimate Diamonds, specifically Gem for all the help when buying my engagement ring and diamond. I had a really tight time frame since I was proposing in Europe but Gem made everything happen within the time frame he promised. The ring took my fiance's breath away and it truly wouldn't have been possible without Gem and everyone at Ultimate. I will be a future customer especially when I buy our wedding bands.

    My boyfriend and I were browsing Diamond District for an engagement ring when we saw Ultimate Diamond and decided to check it out. It was almost full but we were helped immediately. Nirvana did a great job taking notes on what we were looking for and brought me a number of stones that matched my (very detailed!) criteria. She was able to get my ring set and ready to go in 2 days. We had a great experience, thank you Nirvana and Ultimate Diamond!

    I've been here twice. Once for a watch for myself, and most recently again for a ring for my girlfriend. These are the only guys I trust on the street. They are fair, conscious of your budget, and will work with you on price or trade to get you into what you want. My most recent experience was with Mike Shim. He made me feel comfortable and educated me on the product. He made a very fair offer when he learned my preferred price and was a pleasure to work with.

    Such a great experience buying my watch from Avi and Athiana. They are true class acts, honest and fair.. not so common on 47th street. If you’re in the market for a new watch, you need to go see Avi and his team.

  • 5/5 Robert B. 3 years ago on Google
    Ultimate Diamond is outstanding! I came here to buy an engagement ring and they provided outstanding service from the second that I walked in. Gem is the man! Really great guy who took the time to walk me through the basics and showed some really nice options. The ring itself came out beautiful! My now fiance said Yes, loves the ring, and it gets great compliments. Would absolutely return and recommend. Thanks again to Gem and the team!

  • 5/5 sam k. 2 years ago on Google
    We got our wedding bands from Brian, and the whole process has been extremely pleasant! Price was very reasonable, compared to both online stores and nearby stores in diamond district. Resizing the ring, engraving all were pretty straightforward, and rings also came out on time! Highly recommending!

  • 5/5 Alison C. 2 years ago on Google
    We worked with Gem to create our dream ring and he made the process so smooth, transparent, reliable, and went above and beyond educating us on everything we needed to know. He made himself available for over an hour on two separate occasions and over the phone countless times. He created the most beautiful ring and made us so happy. We can’t wait to come see Gem for our bands and any future jewelry need!!! Ultimate Diamond is the best!!!!!

  • 5/5 Moe M. 2 years ago on Google
    My husband and I did not know where to start or knew anything about diamonds or engagement rings- we were completely clueless. We live in Houston, Texas and visited a numerous amount of jewelry stores but always left not satisfied. My sisters engagement ring is from Ultimate so when I told her I could not find anything up to par in Texas, she recommended I go to Choi from Ultimate Diamond and I will say, it was the BEST decision we have ever made. We flew into New York to meet with Choi and it only took one visit to start the process of customizing my engagement ring. She was very informative and patient with us and we did not feel rushed or forced into anything which is what I loved about this place. This review is long overdue (I got engaged 11-15-19) but Every time I look at my ring, I have this huge smile on my face. Thank you for making my dream come true Ultimate Diamond!

    We were looking for to buy GIA diamond stud earrings for a while. After seeing reviews from ultimate diamond, we called the agent. First we spoke with Moshe on the phone. Then we made appointment. He was very friendly, kind and honest. They have so many inventories available. Moshe showed me all different sizes and clarity. He is very patient and not pushy. The prices are reasonable and I would say the best price in the diamond district. The owner lady set the earrings for me in half hour. We could check the laser inscription at the store too. I would highly recommend anyone who is looking for diamond. I will definitely come back for future if I have to buy.

  • 5/5 Larra H. 3 months ago on Google New
    We had an amazing experience with Avi! He was kind, patient, and very thorough. I recommend stopping by and letting him find you the watch you’re looking for. The women helping with jewelry were wonderful as well. We were looking for soemthing specific and they took the time to understand our request and find the best solution.

  • 5/5 Matt S. 2 years ago on Google
    Great staff! I wanted to make sure I had the perfect engagement ring for my fiancée. Gem and his staff were amazing during the whole process and they delivered a magnificent diamond for her. This was the first time I’ve ever bought jewelry and they not only helped me pick the perfect stone, but helped educate myself on diamonds before even making a purchase. We are both excited to do the wedding bands from this wonderful business. Customers for life!

  • 5/5 Thomas M. 2 years ago on Google
    John Kirali of Ultimate Diamond helped me pick the perfect engagement ring for my fiance. He was extremely knowledgeable and able to answer any questions that I had. He also went above and beyond and stayed after store hours to help me get my ring sooner than I had expected so that I could propose earlier. The rest of the employees who I interacted with were just as friendly and helpful and this store had a wide selection of quality diamonds to choose from. All around great experience and I would highly recommend

  • 5/5 Jackson G. 2 years ago on Google
    I walked by with my fiancé and ran into the inventory guy. He told us to come in, from that moment on it was the perfect place to purchase a engagement ring. Brian with the inventory guy were amazing with their customer service. They didn't pressure us. They were genuine interested in matching you with your ring. My fiancé love how attentive they were with her. As a simple guy that was overwhelmed at so many stores it was nice to come across Brian in the Ultimate Jewelry Designs. He made the whole experience 100% better. So thank you, i will be seeing them in the future for anniversaries, birthdays and more.

  • 5/5 Ria M. 4 months ago on Google
    Absolutely amazing experience - we worked with multiple people for my engagement and wedding band. Recently shopped with Athianna and though the store has a great collection, we had a specific vision in mind and she was able to help us with a completely custom order down to every last detail. She was so kind and even made suggestions to help us along the way. The owner Moshe is really sweet and will work with you to get something to work in your budget. We’ll honestly probably be back here for every jewelry purchase.

  • 5/5 Vaidehi M. 1 year ago on Google
    We had an exceptional time working with Brian from Ultimate Diamonds. He worked tirelessly with us for months to source the perfect stone and create a dream ring— all while ensuring we were getting exactly what we envisioned. Along with my engagement ring, we also got my Husband’s band from there. Spending so much on something so meaningful can be frightening, especially this being our first time buying fine jewelry in this country. He made the process as stress free as possible, very informative and with full transparency and we are so in love with the result. Having something 100% unique was my our goal, and this dream team definitely delivered! I don’t think we will ever purchase fine jewelry anywhere else again!

  • 4/5 End 9 months ago on Google
    The first stop to choose the engagement ring had some uneasiness since the person I had the appointment with didn’t even know I was waiting for her but that blame would fall on the window ladies who didn’t tell her. Otherwise the experience was flawless. And would definitely go back again. Diana was wonderful and knowledgeable.

  • 5/5 Zubda M. 1 year ago on Google
    Carlos helped my brother pick out his perfect engagement ring! Carlos was so patient and knowledgeable, as he walked us through cut, clarity and color of various diamonds! From here on out, We will definitely be purchasing all of our diamonds from here!

    We came back for another purchase and Nirvana could not have been better! She - and team - exceeded expectations yet again. We had rings created from older rings and they exceeded our wildest dreams. Nicole was also very helpful with another transaction. The whole team is delightful and take the time to care about your preferences. Well done team - we'll be back! E&E

    Amazing place to get your wedding bans/engagement ring. Lovely staff, I had the pleasure to work with Avi . He’s the go to guy for rings and watches. He has excellent customer service and good demeanor. He’s goal to match you with what you want. I give Ultimate Diamond a 5 star rating look out for Avi and ask for him.

  • 5/5 Michael F. 9 months ago on Google
    Cannot say enough about Mr. Avi Aminov ! He made it not just about a transaction, it was way beyond that. The experience and level of knowledge provided was unrivaled. Avi helped me hand pick the exact Rolex model, size and style for my dads 60th birthday present. I flew directly to NYC just to go to Avi in the world famous Diamond District. I know he will always hook me up no matter the request. A must visit for any watch enthusiast!

    The team at Ultimate is incredible. If you are looking for an experience in the Diamond District where the focus is on you, not trying to haggle you to buy the most expensive piece and to be treated as family, this is the place to go.

  • 5/5 Elizabeth O. 3 years ago on Google
    Wow they are the absolute best in the industry. My husband and I are extremely happy we found Ultimate Diamond. We met with Gem and our experience was amazing from start to finish. We were both very impressed by the level of customer service and attention to detail. They have the most beautiful stones and an impressive inventory. Our first visit was on Saturday afternoon with no appointment. From the moment we walked in we felt welcomed. They took their time and showed us some options, ZERO pressure as we were still deciding on the type of necklace I wanted. They were not pushy or salesy on the contrary we felt at ease. We have visited a couple of shops and they did not compare to Ultimate. Me and my husband decided that this is the place that we want to do business with. We went back and Gem took care of us, showed us some round cut stones and he helped us picked the most beautiful one according to I was I looking for. He listened to every detail and he created the most beautiful piece. My solitaire pendant, a classic and timeless piece. I can not stop looking at it, is breathtaking. The entire staff were all amazing, they are true professionals. This is the only place you should visit when shopping for diamonds. Thank you so much you were a pleasure to work with.!!!

    Gem at Ultimate provided me with an amazing shopping experience for engagement ring. He understood I was very focused on the details of the stone and we tracked down the exact stone I was looking for, a very elongated oval at the precise carat size I wanted. His selection really exceeds what everyone else on the block has. Gem is a wholesaler so his prices cannot be beat. He offered full transparency, we even looked at the stone through a 30x microscope! He was patient with me as I came back about 3-4 times with family members to help me pick out the right stone. He was then able to help me translate some pretty vague criteria about the setting I heard second hand from my then-girlfriend's friends into the exact ring my now-fiancé was looking for! I've since returned to the store with my fiancé to get the ring resized as I did not have the right ring size originally. She loved the store, as its clearly quite classier than many establishments on the block.

  • 5/5 Dan Y. 3 years ago on Google
    Had a great experience here, with the excellent assistance of Gem. He helped me craft the perfect engagement ring and was a informative guide throughout the process. Best spot in the diamond district.

  • 5/5 Maziar S. 3 years ago on Google
    My fiancé and I came across Ultimate Diamond by chance and our experience with Gem and Choi left an everlasting impression worth sharing. First time in the store we met Gem and were warmly welcomed without an appointment- he took the time to ask what we were looking for and encouraged us to browse their inventory, no pressure at all. Very large selection of beautiful pieces in store. Gem was very transparent and honest about the process and pricing of ordering specific diamonds. He has a wealth of knowledge in the diamond industry and many successful years of experience in his business. Right away we felt we were in the hands of someone we could trust and was passionate about delivering exactly what we wanted. We came back several times and also worked closely with Choi - she was very accommodating with our schedules and took the time to provide us more knowledge about emerald diamonds beyond the 4C’s. She was very patient and worked hard to deliver various options of emerald stones with the qualities we desired within our budget. Very appreciate of all the time she spent with us. When we picked out “the one”, Gem and Choi both helped put the vision together with our chosen stone in creating a complimentary setting that would enhance the center stone. Timing to create our ring was less than two weeks. The end result turned out better than we could have imagined and we are so happy with our stunning engagement ring and the wonderful process that we both took part of as a couple to create it. From beginning to end, we were treated like family and are very grateful for the outstanding level of customer service, professionalism, transparency and workmanship that we experienced. We would highly recommend Ultimate Diamond to others and will certainly return for any special pieces in the future.

    We've had a great experience working with Jane from Ultimate Diamond for my engagement ring and our wedding bands. Our price point and style were a bit more modest than some of the rings you see featured in the store and on their Instagram, but they helped us find exactly what we wanted and we never felt that we were any less important to them than other clients, or pressured into spending more. They have been timely, professional, and responsive every step of the way. Highly recommended!

  • 5/5 Jason Z. 3 years ago on Google
    Gem and the entire staff at Ultimate Diamond were incredible to work with and I could not have had a better experience. I started the process of buying an engagement ring without any real diamond knowledge or idea of what I wanted, so I began using the big retail websites to get a sense of options, but it was still overwhelming. A friend then referred me to Ultimate and I’m so grateful I listened. I worked with Gem who took the time to educate me on the different C’s and help me focus on certain characteristics that would help me find the perfect stone within my budget. After looking at a few options for settings, I found the perfect one and my fiancé could not be happier. All of our friends and family are in love with the ring and are constantly asking to see it up close. Gem will treat you fairly and respectfully and for anyone looking to start shopping for engagement rings, I could not recommend Ultimate Diamond Co enough!

    I had an excellent experience with Abe in purchasing an engagement ring. I didn’t know much about diamonds, but in my first visit Abe coached me through it and showed comparison after comparison until I had a good understanding (with no pressure on buying anything at all). We stayed in touch for some time and he later helped me pick out the perfect diamond for the setting within my budget. Great experience, very comfortable and easy. I would highly recommend. Ultimate also gives you GIA documentations for the diamonds purchased along with an appraisal.

    Abe is the absolute best! We had many other experiences prior to going to Ultimate Diamond and meeting Abe, and we are so happy to have worked with him! He is incredibly patient, knowledgeable, honest, and trustworthy. Throughout our interactions he proved to be very responsive and attentive to all our needs. His friendly demeanor and excellent customer service will definitely have us going back to him over and over in the future.

    My wife and I found Abe and Ultimate before we got engaged in 2011. We are very proud to have a near 10 year relationship with Abe because of his honesty, transparency and commitment to making my us happy. I’ve referred my mother, sister and countless other people to Abe and everyone is just as happy as we are. We’ve purchased many items from Abe and Ultimate over the years and look forward to continuing our relationship for many years to come. Highly recommend!!

    Gem is truly amazing. I’m absolutely in love with the engagement ring! My friends referred us to Gem because they purchased their engagement ring with Gem a few years ago. Our experience with Gem was fantastic from beginning to end. Gem took the time to give us a comprehensive presentation on the 4Cs. He was very transparent and has a wealth of knowledge in the diamond industry. We were both impressed by the level of customer service and his attention to detail. It took us 2 trips to finalize the diamond and the setting, and Gem was extremely patient with us and he made us feel very comfortable. When we picked up the ring, he helped us look at the stone through a 30x microscope! This is the only place you should visit when shopping for diamonds and I would love to come back for jewelries in the future!

    My wife and I went to Ultimate Diamond following a friend's recommendation and we were thoroughly impressed! We walked in with a bit of hesitation after being harassed by a number of other store owners on the street but the hesitation went away quite fast as soon as John Kirali welcomed us in. He guided us through the shopping process with professionalism, courtesy and charm. We had a specific design in mind, he showed us beautiful options such as classic diamonds and colored diamonds that could go well with it. We had a tight deadline and thought to take the time for this gift but John assured us that he was able to deliver the ring within a week. And deliver, he did: the final result is beyond our expectations. The jeweler improved the idea of the design smartly and he has definitely a good eye. I would definitely recommend.

    Ultimate Diamond is fabulous! Super friendly and efficient staff, great experience overall. I'll be honest, I'm not one to write many review online, but these guys were so great that they really deserve to be praised. When my fiance and I first started shopping for a ring I had literally no idea what I wanted, or where to get it. Eventually I found two rings that I loved, one from Cartier and another from Graff, but we wanted to replicate a combination of these rings in yellow gold (and without the price that comes along with the brand name). My fiance resorted to the internet and almost purchased a ring online, and we're both so happy he didn't. It makes all the difference to see rings in person, and to work with someone directly. So to find the "perfect" ring, I joined my fiance in the diamond district. We must have checked out at least 10 shops that day until we stumbled into Ultimate. Some of the other shop owners were horrible with us, saying "come back to us when you know what you want." These guys weren't like that at all. Why did we end up moving forward with Ultimate? Not only did we like their rings, but we had a good feeling about the place. The employees were so nice to us, and patiently put up with me trying on every combination of rings possible. It was the only shop that let me try on a mix of platinum and gold, engagement rings and wedding bands, etc. I was sold. My fiance designed my engagement ring entirely with Choi, and from what he told me it was a great experience from start to finish. She paid attention to every little detail that he wanted. Best of all, my ring turned out perfect (and I believe nothing is perfect)! I recommend Ultimate 100 percent :) We got our wedding bands here as well, and whenever I go back Abe is welcoming and happy to clean my ring for me or make any adjustments. They're wonderful!

    My husband and I love coming to Ultimate Diamond - working with Choi is always a pleasure; everyone is very professional, courteous, and provides first-class service. I got my engagement ring set here and we loved the experience so much my husband and I came back for our wedding bands. Prices are very reasonable, and they are knowledgeable and passionate about the business they are in. There is no pressure at all, they truly care about making you happy and getting you what you want. We will continue to come back and highly recommend Ultimate to absolutely everyone for top quality fine jewelry and amazing service. Thank you!!

    Jane at the Ultimate Diamonds is the absolute best! She not only helped my husband pick out the most beautiful engagement ring but she helped us both with our wedding bands as well. You know when you go into Ultimate Diamonds you are going to get the best of the best and staff that cares about getting you the perfect piece of jewelry. Jane also helped my husband with a beautiful garnet necklace as a wedding day gift . She is our go to and we highly recommend going here if you are in need of the perfect gift for your significant other.

    Choi was absolutely amazing. We knew that this was the right place to trust. The customer service was unmatched and the custom work is beyond stunning. I couldn’t be happier. We will never go anywhere but Ultimate. Thank you guys!

    Ask for Abe. He is magnificent, as was our entire experience. Zero pressure, wonderful staff, beautiful store and gorgeous diamonds. I walked in with a tennis bracelet from Cartier and asked Abe if he could make a necklace of the exact same quality. A week later we walked away with TWO amazing pieces that will be in our family forever-- the stunning 18" tennis necklace and an absolutely breathtaking colorless pear-shaped pendent. It bears mentioning that both pieces together were a similar price of brand name bracelet alone. In that respect, the value was unbeatable. We will always go with a small business if they can create the same or better quality product and in this case, we were absolutely thrilled with the result. Come see Abe at Ultimate and make your diamond investment go further. We have found our jeweler for life and look forward to our next visit!

    Due to my circumstance I only had a few days to plan my big proposal. I had an idea on what I wanted for a ring but I was stressed I wouldn't find it in time. From the moment I walked into the store, my confidence was a given boost. Gem and company were beyond welcoming right from the moment I stepped into the store. The atmosphere is exciting with happy couples are looking at jewelry and also relaxing. I was coached on the diamond 101 by the staff. Gem is a class act understood what I was looking with just a brief description I gave him. From this point it was just tweaking the size and matching similar settings. After a few exchanges of the pieces we landed on gorgeous ring that my soon to be fiancé would adore. I could not be happier with my experience at Ultimate Diamond Co.

  • 5/5 Joe B. 4 years ago on Google
    Ultimate Diamond Co. should be every man's one and only stop when it comes to finding the perfect engagement ring. As soon as you walk in the door, you are met by friendly employees, who are all exceptionally knowledgeable in their craft. I worked with Choi and she made my entire experience a truly memorable one. Walking into a jewelry store can be overwhelming to a lot of guys - but Choi and the entire staff at Ultimate made my entire process as easy as possible. With Choi's help, I was able to design the perfect ring. I will definitely be working with Ultimate for my future jewellery needs. I cannot thank Choi and the entire staff enough for the time, preparation and attention to detail they exhibited when working with me. I never felt rushed or pressured, which is certainly not the case at a lot of other jewelry stores. Ultimate has made me a customer for life. I cannot recommend them highly enough. Thank you!

    I’d like to start this off by saying that my fiance’s ring is absolutely absolutely absolutely stunning. Gem Sezgin and his coworkers at Ultimate Jewelry are fantastic at explaining, leveling with you, and are very upfront and honest about what you’re looking for, and what can be done. They are also very true to life wholesalers. A few tips to finding the perfect engagement ring and using Ultimate correctly: DO: Shop Around (you will see through process of Elimination, that Ultimate is by far the best pricing, and customer service. DO: Know what you want. Cut, Color, clarity, GIA certified, type of setting (with accessories) Everything here is custom built to order. Learn from the other stalls and stores what you like. Blue Nile is beyond helpful. DO: Go to Tiffany’s and the other overpriced on 5th and Madison, Play around, drink the Champagne and get pampered. See what she likes, bring it to Gem and his people. Bring pictures!!!! DO: Ask friends for their recommendations. Use them as a reference, then talk to Ultimate. DO NOT: Follow the guys off the streets into their stores. DO NOT: Be pressured into high pressure sales. Or be told what “can be done.” If it’s possible, Ultimate will. Counterfeit/Chemically altered stones do exist in NYC Diamond District. Beware of extreme price haggling. DO NOT: Buy anything that’s in a glass case, if you like it, get a spec sheet, bring it to Ulitmate. DO: Celebrate what Ulitmate can do, and expect a loose expectation on turn around time. Customer built to order is built in a few weeks, not a few days, but will blow you away, be excited, but patient. DO: Happy wife is a happy life…… Healthy READ ALL YELP REVIEWS FROM PLACES and JEWELERS SHOPPED, INCLUDING ULTIMATE, YOU’LL SEE!!!!!!

    My fiance and I are so happy we wandered into Ultimate Diamond Co.!! After shopping all day at various jewelry stores for an engagement ring we were frustrated that the experience was just not what we had imagined (some shooed us away, others quality seemed low, some stores prices crazy high, many didnt seem to care about earning our business or lacked inventory) Ultimate Diamond Co was the last place we went, towards the end of the evening. I could tell from the moment we walked in that it was different from all the other stores. I was greeted with a warm smile and helped right away. Billy sat me at the counter and listened to what we were looking for. There was a ton of beautiful engagement rings there but they can also customize. Billy spent so much time with us patiently educating us on 4C's and beyond. We werent sure we were going to purchase that night and Billy never pressured us or made it seem like we had too. Ultimately we did pick a ring that night and purchased!! It is absolutely gorgeous and it cost HALF of what they charge in those mall box stores) and much better quality diamond too. I get compliments on the ring all the time. When my fiance decided to purchase they popped some champagne for me and some good scotch for him... It was my dream ring shopping experience!

    We have gone to Jane at Ultimate for many jewelry accessories. Most recently we went for our engagement ring and wedding bands. They are very welcoming and engaging. Takes the time to explain what you’re buying and does not pressure you into making any decisions. They work with you to find exactly what you’re looking for. I highly recommend this dealer and promise you will be disappointed! Thank you Jane! -J&M

    I highly recommend Ultimate Diamond for your diamond purchases and request Jane! We worked with Jane to select the engagement ring and our wedding bands. She is extremely knowledgeable and answered all of our many questions. She made us feel comfortable during the shopping process and was so easy to get along with. The customer service is top notch and the diamonds are stunning!

    Ultimate diamonds is a special place. Gem is truly fantastic and I have been back there many times - always feeling great about the product and service. Most recently to buy the first pair of diamond earrings for my oldest daughter. I intend to keep going back for many years to come as I always get treated as family.

    Amazing work and amazing help from both Choi and Abe to make my fiancee's fantastic engagement ring. We were so happy with it that we got our wedding band as well :)

  • 5/5 Gil P. 4 years ago on Google
    Great service from Choi. I requested several diamond to the store from my own research and Choi was very helpful and knowledgeable. Prices are good and willing to negotiate. Choi had some good recommended & options. you should do your own research to learn the diamond world before going to any store for shopping.

    Ultimate Diamond provided a once in a life time experience. They did an amazing job with my now Fiancé’s, engagement ring. It is absolutely beautiful. While shopping in the Diamond District the moment I stepped foot into the store I felt the “this is it vibe” in my gut. Billy helped me through the entire process. He was very knowledgeable and made me feel comfortable throughout the whole experience, explaining each step of the process of purchasing an engagement ring. He never made me feel pressured in any way and just wanted to ensure that ultimately I was happy with the final product. After showing me a variety of diamonds of all shapes, sizes, clarity and color, finally one stood out and I knew it was the one. We are thrilled with the outcome and hope to work with them again in the future. I would highly recommend for any jewelry needs. They are a 10/10.

    As I walked into the store, I was greeted by Rohan. He was very personable and made me feel at ease. It was refreshing to have a no pressure/no up-selling experience. He stressed the fact that Ultimate Diamond is not looking for customers, but relationships and he definitely embodied that. I gave my budget and my preferences and when I came back the next day, there were several options waiting. Rohan did not just provide options at my max budget, but ensured he can find me amazing options well under and he did. Most importantly, I really needed the ring in time for a New Years proposal and they got it done! Thanks to Rohan and the UD Team, I was able to have an amazing proposal and memory.

    Zina and Athianna were so incredibly helpful and patient. When I couldn’t find exactly the wedding band I wanted, they helped me design a custom band which was reasonably priced and came out flawlessly. They were even available via text to answer any questions I had. I highly recommend this store! I would definitely trust them again for any future diamond purchases. (In the photo, the engagement ring was not bought from them but the wedding band was)
