I had an absolutely wonderful experience working with Dino and the team at Market Street Diamonds. They were super helpful, clear about timelines, and accommodating of my desire to incorporate the stone from my grandmother's engagement ring into a new design. Honestly, I can't think of a way in which the process could've gone more smoothly. I would recommend MSD to anyone looking for honest, quality, professional service and great products.

I brought in a pair of heirloom hoop earrings (85-90 years old) that were handmade by my great grandfather because the clasps for one of them stopped working. I wear them nearly everyday so I was really worried about finding someone to fix them properly. They fixed them within a few minutes and didn't even charge me for the service! Just looking around the store while I was waiting showed some of the most beautiful jewelry pieces I've seen in a while so I highly recommend checking them out.

After Brilliant Earth screwed me over, I called these guys with less than 2 weeks to the proposal date. Surprise to say the delivered. Amazing ring, great detail, happy wife, happy life! She flew to Saudi and the royal family complimented her on the ring. At least I did something right! They were able to custom make a wonderful piece and have it done before a flight overseas on a tight deadline. Thank you. I appreciate your customer service and skills from one business owner to another. Thanks.

I had a wonderful experience working with Eva at Market Street Diamonds in August 2023 ahead of my proposal to my girlfriend at the time. When I first came in, I was at a complete loss at how to go about the process. My grandmother had given me her own engagement ring's diamond to clean and reset into a new piece. Eva was extremely patient and helpful in working with me to go over the different options at hand, including the setting, band type, and accessory diamonds. Despite the short timeline I had, Eva was able to help me put together a design that my fiancé ended up LOVING! The quality of the final product is just as impeccable as the customer service.

I had no idea what I was doing. I had never spent any time in a jewelry store and I had no expectations on what jewelry shopping entailed beyond what I had experienced walking into a few stores that day. Then I came across Market Street Diamonds. This place set a bar for service I have not experienced anywhere else. Daria immediately greeted me when I walked into this Georgetown row house-turned-storefront. Daria spent over an hour showing my girlfriend different pieces of jewelry while asking questions about her taste, style, interests, and hobbies to guide her around the store. My girlfriend (now fiancé), who had had not shown too much interest all day at the other locations, was trying on half the store. Even I had fun. I returned to the store alone two days later and from there, Daria probably sank 6 hours with me working on the design and finding the right center stone over the course of a month. Of note, the stone I wanted was a very rare Alexandrite that Daria had to track down by making phone calls and emails to specialty jewelers when she wasn’t working with other customers. Just as impressive as Daria’s service and attention to detail, Market Street Diamonds somehow managed to turn my chicken scratch drawings into a beautiful bezel design with their extremely talented CAD team. And yes, they are the real deal, working in-house with an on-site 3D printer. And it did not end there. After she said yes (on a mountain in Patagonia) Dino, free of charge, altered the size and shape of the ring to fit her hand perfectly. Bottom line is, this place has a 5 star rating on Yelp for a reason. The MSD team is warm, fun, and happy to help bring whatever you have in your head to reality. I will be a returning customer for as long as I remain near DC.

I have nothing but overwhelmingly positive things to say about Dino and the Market Street Diamonds team. They are warm, friendly, professional, and truly deliver an amazing customer experience. My (now) husband and I had a custom engagement ring designed using stones from both of our families, and it turned out more amazing than I could have hoped and then came back to MSD for our wedding bands. We told Dino which pieces we want to integrate, provided some inspiration images for pieces we liked and then I said "I really love peonies and English garden roses." The ring he came up with is stunning. I could yell positive things about this design for years. MSD was fully transparent about price and didn't charge a design fee. We ended up with a piece that cost less than a standard "box" store with 1000x more meaning. Highly recommend. 15/10. Only thing I will say is that beautiful art takes time. This process took place over several months. I'm sure they would be willing to work with a more condensed timeline, but why rush perfection? For our bands, we had a custom ring designed to fit my engagement ring and my husband chose one of Dino's speciality men's bands that allowed for engraving on the bevel. They're stunning. Dino perfectly matched an emerald in my wedding band to the emeralds in my ring and engraved the platinum with a vintage scroll design...little did he know that my dress and veil both featured scroll lace. Perfection. Will be using them as our jeweler forever.

I worked with Rayna on creating a ring as a "push present" for my wife to celebrate our first child back in December. Even during the craziness of the holidays Rayna took the time to make sure I felt valued as a customer and was given the utmost care and attention. I shared a few designs for the ring with Rayna and she gave me valuable feedback on each and helped craft a final design that my wife LOVED. Highly recommend Market Street Diamonds. I've worked with other jewelers in the past and they are head and shoulders above the rest.

We could not be happier to have chosen the team at Market Street Diamonds to create our wedding rings. Their entire team is so knowledgeable and welcoming, you can tell they truly take pride in their work and it shows! We went into the showroom to pick out wedding band styles a couple of times and they were so patient and informative in the process. They worked with us to set a budget and make sure the engagement ring and wedding bands fit our budget, style and lifestyle. We have stopped into the showroom many times since then to pick up the wedding bands or get them cleaned before the wedding day and they always remember our names and make the place feel so welcoming. The rings turned out absolutely stunning. I have had my engagement ring for three years now and I still catch myself staring at my left hand in awe of its beauty. Thank you, Market Street Diamonds team for making the rings of our dreams. You now have customers for life.

They resized and beautifully restored my 1920's era engagement ring and wedding band. They also created a custom necklace for me. It is so delicate, gorgeous and exactly what I hoped for. I could not have better things to say about the service, the attention to detail, and the artistry of Dino and his team.

I had the best time designing a custom, sentimental piece with Rayna’s help. She was there for every step, giving me design ideas, helping me decide what I liked. She was also honest about what may or may not work together and super knowledgeable. most importantly though, she made it FUN and helped me create a piece that I absolutely love. Thanks to Rayna and Dino for such a special experience.

Sized my Harry Winston engagement ring in a way that messed up the band (it is clearly not flush to the eye or touch) AND ruined a 4th generation Swiss pocket watch after reassuring me multiple times they could monogram the same way by hand. When I picked up the watch it was a different size and font. So they said they could fix it and instead of welding it they used a laser WITHOUT EVEN OPENING THE WATCH which damaged parts inside of the watch with the laser. So now, this 100 year old watch that they assured me they would take care of has been damaged where they poorly monogrammed and imperfectly lasered over AND damaged the actual mechanics of the watch by lasering through the back without even opening it. What concerns me most is the repeated reassurance that they could do everything I asked as asked and then failure to do so but then(!) almost criminal treatment of a treasured heirloom without complete disregard. Just say you can’t do it and let me maintain the integrity of my jewelry. I’ve finally gotten to another jeweler in NYC who is determining the amount of damage I have to pay to fix from Market Street Diamond’s mistakes. 2 strikes and I’m done with them forever. Don’t believe them if they say they can do it, they clearly don’t mind overpromising and under delivering.

Dino and his team are the absolute best to work with. From our first meeting designing my dream engagement ring, to our wedding bands, and going in for cleanings now and again, they always feel like family. They walked us through the entire ring shopping process with so much grace and kindness. We love MSD!

Market Street Diamonds has earned a lifetime customer here. My wife had a necklace that had initials and birthstones for our two kids. When kid number 3 came along, I weighed the options of buying an entirely new necklace, or seeing if I could add a third initial and birthstone to the existing chain. After being told it was "too hard to do" by 2 other reputable jewelers, I asked Dino at MSD if he thought it could be done and he said "no problem!" Not only was he able to match the hardware for the initial perfectly, but symmetrically added the third birthstone as well. I was blown away by the impeccable workmanship, as well as the service, which was like dealing with a family member. Dino gave me constant updates throughout the process and provided me with several options. I give MSD and Dino my highest recommendation.

We trusted MSD to set my grandma’s family heirloom diamond into an engagement ring and they did not disappoint! They advised us on the design and did a beautiful job. We went back for our wedding bands. Excellent experience overall and we could not recommend them more.

My fiancé absolutely loves her engagement! It turned out better than expected and the staff has been professional and timely since the beginning. We got to work with Eva and Dino, and I can’t say enough good things about the experience. I highly recommend getting your ring here or at least walk in! You won’t regret it, I promise :D

Dino and his team at MSD are hands down the best jewelers in the DMV. Selection, quality and customer service are all first-rate, and they have fabrication and cutting capability onsite, which is extremely rare.

Polina was absolutely amazing for our first appointment for an engagement ring. Market Street Diamonds is very accommodating with customization and seems to have a large selection of lab grown diamonds. I’m excited to continue the process with them

I had a very specific, nontraditional design in mind for my engagement ring, that I knew would have to be custom made. To ensure I got a ring I loved, my fiancé and I opted to go through the engagement ring shopping process together. Neither one of us had any experience with Jewelers, engagement rings, diamonds, or custom jewelry, but lucky for us, a friend of ours suggested we go see Dino at MSD. BEST RECOMMENDATION EVER! The experience was so overwhelmingly positive and easy. During our first appointment with Dino, I explained the design I wanted, which was based on a custom ring my mom had designed by a jeweler years ago with a few minor tweaks. Dino took his time to listen to what I wanted, look at my mom’s ring, ask us a few questions, and gave us some valuable insight on a few things. He did all of this without pressure or judgment. He also asked my fiancé about his budget, because he wanted to make sure the ring he designed stayed in budget, which it did. Two weeks later we went in to see the wax mold, 3D CAD image, and the diamond….. we ended up pulling the trigger right there on the spot. I’m not one to rush into large purchases without some due diligence - so when we first started the ring shopping process, we had planned on shopping around before making a decision but Dino was our first stop and after seeing the CAD image of the ring he designed for us (exceeded all my expectations - it was love at first sight - which, for me, is rare - just ask my fiancé ). Just like that, I had no interest in shopping around. Over the course of the next three weeks, practicing patience was very difficult for me, I had gotten a glimpse of my engagement ring, and I was SO READY to have it on my finger. Before I knew it, the wait was over, and it was so worth the wait. There are no words to express just how amazing our experience was. From start to finish, Dino and his team are exceptional. There is no question, they know what they are doing, they do it well, and they clearly care about their work and their customers. Thank you, Dino and MSD!

Dino and the whole MSD Team were an absolute dream to work with. When we came in to discuss both of our engagement rings, Dino was thoughtful in helping us to take our time to think about what we really wanted. The end result was absolutely stunning for both rings. Maggie and I got engaged in Asheville, NC last May, and married this summer, and we still can’t stop looking at our rings (each of our engagement rings, and our matching wedding bands) every single day! We can’t recommend MSD enough for anyone thinking about getting engaged and wanting a truly unique and beautiful ring (or rings!).

I found MSD by chance on Google and it was truly the biggest blessing. I was in a bit of distress due to some other jewelers’ assessment of my family heirloom engagement ring and Eva as well as the rest of the MSD team not only gave me the emotional reassurance I needed but they did a flawless job resetting the diamond and ensuring it’s safety for years to come. I really can’t say enough good things about this team and their craftsmanship. You can tell that diamonds are their passion and I couldn’t be more grateful to find them. They will be my go-to for all future jewelry needs.

Highly recommend going to MSD and asking for Rayna! She was super welcoming and helpful while I was looking for an engagement ring. What stood out was that when I walked into the door Rayna introduced herself and then asked me questions about myself and my girlfriend. She really spent the time getting to know my girlfriend and I and never brought up money or budget. She got to know me and I got to know her and this was so nice. She asked me what kind of design I had in mind and always asked me for my opinion and thoughts before sharing hers. She really wanted to create a ring that my girlfriend like and wanted and that I also liked. She even pointed me to do research during our first encounter/meeting to really put in the time to look at the perfect ring that I wanted. She never rushed me and even told me to go look at other jewelers which was so surprising. So I did the research and even went to other jewelers. However I had such a different experience with the other jewelers. They never really asked about me and my girlfriend, and more so on what kind of ring I wanted and my budget. It really felt homey with MSD. I went back to MSD after researching and knew they were the perfect place to do the engagement ring for me. Through the next 3-4 meetings: I showed them the design I wanted, I picked out the center diamond I liked, they created CAD design and 3D print of the ring (so cool), and then saw the finished product! The ring was stunning and my fiance absolutely loves the ring. It was so easy and nice to work with MSD and Rayna and HIGHLY RECOMMEND THEM! Thank you so much for everything Rayna and the MSD team!

Dino has an amazing attention to detail and created several pieces of jewelry for me. I can't imagine using anyone else. He also has gorgeous, one of kind pieces that are now on my wish list!

My fiancé and I could not be more pleased to have designed and gotten our ring at MSD. They set the bar (real high) for how a customer should be treated to guarantee return business. During our first visit, we met with Eva, who would accompany us through the design process and many questions. I brought her examples of what I like from Pinterest and Etsy and she educated us on the pros and cons of different stones, metals, designs, etc. She was mindful of our preferences, non-judgemental, and informative about: 1. diamond rating/classifications 2. sticking to a budget and communicating what kind of details on the ring would significantly add to cost (came out under!) 3. us designing the ring together but the proposal being a surprise 4. financing options 5. insurance options 6. timeline Before you stop reading: we SAVED money custom designing this ring. I went online to Kay Jewelers and Jared and was surprised to see that similar ready-to-ship rings were going for 2-4 times what we had paid for my dream ring. The design process was mostly over email, with some in-store visits, but I am sure they would customize it to your desired interactions. They make sure to give you all paperwork necessary to insure your piece and recommend a company with whom it is really easy to do so.

If you're looking for a top of the line, reasonably priced custom jeweler, Market Street Diamonds is it. Owner and lead designer, Dino Lonzano, is an artistic maven-- capable of bringing my very specific engagement ring design preferences to life. His whole team was phenomenal from day one-- even before I committed to using them as my jeweler. His staff produced sketch renderings right in store according to my ring preferences. We discussed the "4 C's" of diamonds, band color/shape/sizing, and other stylistic elements. Dino was able to source a stone within my carat, cut, color, and clarity specifications, and below my targeted price. The final product was stunning and my fiancé was very happy. As a customer, Market Street Diamonds provides ring resizing and other basic adjustments at no additional cost. Dino and his team will help you create a truly unique, high quality, and affordable piece of jewelry. My highest recommendation. Customer service: 5/5 Design process: 5/5 Quality of product: 5/5 Cost and willingness to negotiate: 5/5

I haven’t bought anything yet, but when the time comes I will always remember the owners genuine love for his craft and helping you as a buyer. I was so impressed with how the whole experience was that I will never forget and had to leave a review
