We walked in looking for the diamond museum only to find out we were on the manufacturing side. They have a free tour so we gave it a shot. Eva was our guide and she was wonderful! We learned about the history of diamonds, manufacturing process, and how to look for imperfections using a Loupe which was fun! She even gave us some other local recommendations! Unlike some of the other reviews we felt no pressure to buy anything. We ended up purchasing a beautiful Royal 201 cut diamond ring because I'd been looking for something to commemorate our trip. Eva helped fill out all the Global Blue tax information as well. You pay the full amount there, but once you get the customs stamped paperwork you get a refund on tax. This part is about *GLOBAL BLUE*: Make sure you get to the airport early enough to complete this process (and make sure it's open!). The booth is towards the entrance of the airport and before you go through security. I think it took us about 30-40 mins total. We were behind several groups of people that pulled out handfuls of receipts to process!! There are two steps/lines (that must be done in order) I saw multiple people waiting in line2 only to be told to go back to line1 and come back. Step/Line 1: You need to physically show your purchased items to the attendant. Then they will stamp the paperwork (completed by Eva). Make sure you don't accidentally put it in your checked luggage and on its way to the plane, they need to see it. Step/Line 2: This line was much longer. The attendant at this line will review your receipts/paperwork/stamp and ask if you want the refund in cash, or sent back to a card in 5-7 days. NOTE: Eva mentioned if you are not in a hurry, there is a drop box you can put the completed/stamped paperwork. I forgot to ask about this and blindly went into the 2nd line which took forever. If you are in hurry ask the attendant about the drop box!

What ever you do, do not buy a diamond from this place. They are con-artists who charge 5x times the price of a diamond. We made this mistake of overpaying. This place should be illegal. It’s a tourist trap. Please be warned.

Great place! Free guided tour trough the diamond polishing factory where you see diamond polishers and goldsmiths at work. We learned everything about the C's of diamond valuation and even got the chance to wear very big diamonds ourselves. The perfect mix of education and entertainment. Of course, you can also buy diamonds and diamond jewelry. They have the best diamonds in Europe, very high quality. I know they will last a lifetime. Love it!

World's oldest diamond company that makes a unique 201 facet diamond with amazing shine. Other diamonds are 57 faucets or less. They have a lovely free 15 min tour where you can actually see the staff working. Should you decide to buy something they provide top notch customer service and you can even watch them mount your gem (20 mins). If you are a tourist you can reclaim the tax on your flight out.

Fantastic. I was walking past and came in out of curiosity. I asked about the tour, submitted my name, and within five minutes someone came and have new a private tour, showing me the diamond polishers and goldsmiths at work and walking me through the building. It was all completely free, and there was absolutely no pressure to buy anything. If you are in the area and half when the smallest amount of interest in diamonds; go here.

Visited this place as part of the tour and one of the sales representatives attended to us. She explained the process of diamond formation and how a diamond is examined. I guess is a good place to visit for those who are interested in diamonds or would like to gain some knowledge on this aspect.

I cannot recommend Coster Diamonds and especially Danielle enough! We live in the UK and my fiancé contacted Danielle via email about an engagement ring for me. Danielle was very helpful and sent back lots of different options and recommendations to suit our taste and budget. When we made the trip to Amsterdam, she came into Coster Diamonds especially to meet us and gave us a personalised tour and shopping experience where we were able to compare many different diamonds and settings. She is extremely knowledgeable in her field and my fiancé and I both learnt a lot. Once a decision had been made, the chosen diamond was put into the ring within minutes! It is the most beautiful piece of jewellery I own and I love it! We enjoyed snacks and champagne to celebrate and the whole experience is one we will definitely not forget. On top of that, we had some trouble applying for a tax refund as we travelled by Eurostar. Danielle was amazing and managed to solve the issue and arrange for the refund even after we had travelled back to the UK. I would not hesitate to recommend Danielle and Coster Diamonds and we will certainly be back in the future!

It was such a pleasant shopping experience. The advice from the sale person (Bình he was) was spot on and i could feel the genuineness and honesty. I learned quite a lot about watches on top of what I had already googled. On the way, i bought a bunch of other gadgets with discount too (swiss knives etc...).

Very educational for a "diamond tour" but not fun for the wallet. And I found the tour was quite entertaining by one the Indonesian guy with his jokes. Even though I knew I would not be able to purchase anything there, but this man made my day.

The staff member that helped us was called Naira and every time we met with her she was super professional but warm and inviting. She made the experience so easy and we genuinely enjoyed the whole process. We would definitely recommend booking an audience with her if you’re unsure of what you’re looking for. She has a great knack for knowing what the customer’s style is and helped tremendously to make our visits fun and stress free. We would highly recommend Royal Coster Diamonds after our experiences with the staff.

We took the Royal tour. Our host was excellent. This tour allows you to view a selection of top quality diamonds through a Loupe. We would highly recommend this tour.

I used the resparkle service and I was very impressed with the time and care Sophia spent with me. She is old me about the process of polishing diamonds whilst my jewellery was being resparkled and she was very attentive. I highly recommend Coster diamonds for their customer service and quality.

The free factory tour is very fun - we had an excellent, friendly and knowledgable guide. You can see the jewellers working and examine some real diamonds. worth booking online in advance.

Surprised by the afternoon to visit a diamond factory (the best in Amsterdam) and the wonderful Angela was the reason it was such an enjoyable experience. She’s so professional, and has a real passion for her job (even after 18 years) her energy and personalised experienced made the whole afternoon just one to remember. I’ve learnt so much more about diamonds and also about myself and what I like. What a day, and we can’t wait to come back. Thank you Angela, you’re one of a kind ♥️

Very Expensive Shop, very rude staff, they just want to sell you the most expensive items in the shop and guess what they paid a commission for my guide who took me to the shop. I recommended you go to Gassan much better service and cheaper.

Impressive place to visit. Guide of us she really good explain about diamonds for us and really kind.

That was very interesting, we received a German-speaking tour, the lady was very nice and took a lot of time.

It was one of the stopping points of our Benelux-Paris tour package. You can see how diamonds are shaped and the manufacturing stages.

Got caught with a sales person that wanted to sit us down and constantly offer us items outside of our stated budget. This was extremely frustrating and resulted in us leaving without making a purchase. His inability to listen to our wants and continually upsell was upsetting. If you go, stick to your budget and don’t be afraid to leave if they don’t listen.

Visit reserved for 12:30 on 18/02/2024. - very sympathetic lady from Indonesia was our guide in English. - we were a group of 10 which was the right size - duration about 30-40 minutes - it started with a general explanation, the polishing by real craftsmen was shown and we were able to look with a loupe the shape of the diamonds - then in another room we were shown more than 10 diamonds which overall had more than 7 figure value - the explanation was clear, interesting and well communicated - then we were shown the museum pieces and at the final guided into the shop (of course, nothing is more expensive than “free”!). But there was no pushing for purchase. Conclusion: really a good occasion to learn for “free” about diamonds from a famous diamond maker and good duration for little children. Really recommend. Also if you have any intention to buy.

We took the free guided tour and it was spectacular. 100% recommended if you like jewelry and diamonds. Simone was with us, very kind and friendly!!

We had the extreme pleasure of having Mr. Hans Hofstee lead my wife and me through the intricacies of diamonds … from the sourcing to the retailing. Hans was as knowledgeable as he was gracious. He was most willing to respond to our many questions, which we were quick to offer as we the complete attention of an expert to respond to them. We visited Royal Coster on an impromptu basis. It was unplanned and spontaneous. Hans demeanour, experience and aforementioned knowledge made that fortunate choice a most memorable experience. Thank you Hans!

Amazing shopping experience! Angela was simply "the best" in helping with education about diamonds and then assisting with our purchase selection. She provided us with several alternatives, all within the required budget guidelines, and both loose diamonds and premade engagement ring selections. We couldn't ask for a better purchase experience. Than you Angela and Cister Xiamonds!

We have visited the exhibition today. Mr Simone Pilla, our guide, has been extremely professional and polite as well as showing his knowledge. The visit was very interesting and the jewelry was stunning!

Nice place but u r gonna need some extra Cash :)

Amazing staff, the diamond tour is a great experience! The shop offers a lot.

Tourist trap but still a nice shop with nice assortment and reasonable prices.

Awful place! I would nobody recommend to visit it. Extremely tourists oriented, absolutely not-up-to-date, aggressive sales, plus absolutely unfriendly staff with arrogant attitude. Moreover, I was an occasional witness of the incident, in which I wish I would never be their customer!

Free guided tour through a gift shop. No comments

Very nice shop lots of choice

Just having a quick look

Good.

They have very beautiful diamond collections. I do enjoy the tour

Wonderful tour. Our guide explained many facets of diamond processing, pun intended.

This is a tourist-trap visit, factory visit inexisting, guide speaking an English not understandable. Really not worth visiting this; the only thing they will try to do is to sell you diamonds, but for this it shouldn’t be necessary to book a visit. Don’t fall in this trap!

When we visited we got a very interesting "tour" about how diamonds are made ready for jewelry and other uses.

A pretty short tour, most parts of the “museum” are actually the shopping area. The guide who guided us was decent and able to speak four languages fluently. Impressive.

The guide tour was amazing, thank you again to our very nice guide 100% a good diamond experience with her! One of the highlights of our trip in holland

My experience was in 1975! While in Europe, my father insisted on taking his family here. He purchased a Diamond for each of his daughters. Amazing experience!

The 25-min so-called "factory tour" doesn't exist. The staff, whose spoken English was hardly understandable, introduced their diamonds to us very roughly for only 5 mins, then brought us to the shop! He just wanted us to buy something. Very bad presentation and selling skills. I wouldn't buy anything there of course!

Bought 2 rings with diamonds here and the service and quality is amazing. They call you after a year for when your ring is ready to be serviced again and they completely clean it for you.

Really interesting visit. One guide for 2 persons. Explaining how they polish and cut diamond. Then give you lessons how to check if diamond is of good quality or not. Don't go there to see beautiful diamonds but to improve your knowledge on how to do.

This place must be seen. A small tour given on how diamonds are cut and produced, and a chance to see the most expensive diamonds and wear them.

Do you expect a museum?, well it isn’t. The “tour” takes 5 min and then they’ll take you upstairs (to the shop) after that.

Great experience in our first visit in Amsterdam and at Royal Coster Diamonds , thanks to Simone Pilla that guided us in the fantastic diamond world. Edoardo, Eleonora e Sebastiano.

(Translated by Google) Nice to take a tour and take a look at the beautiful range of diamond jewelry (Original) Leuk om een rondleiding te krijgen en het mooie assortiment diamanten sieraden rustig te bekijken

Diamond Bank and good quality diamonds

(Translated by Google) Was a lot of fun, educational and fun. We had a two person tour with a subsequent highthea everything was taken care of down to the last detail with great attention to detail. Very much enjoyed all the beautiful viewing, unfortunately I have no budget for the splendor, but what is it all handsome and beautifully made real craftsmanship and so enjoy the diamond cutting and goldsmith arts. (Original) Was erg leuk, leerzaam en gezellig. Wij hadden een tweepersoons rondleiding met een daaropvolgend highthea alles was tot in de puntjes verzorgd met veel aandacht voor detail. Erg genoten van al het moois bekijken helaas heb ik geen budget voor de pracht en praal maar wat is het toch allemaal knap en mooi gemaakt echt vakwerk en dus genieten van de diamant slijp en goudsmid kunsten.

(Translated by Google) Fantastic buildings and location. Got a free tour which is super interesting. They take their time to discuss all aspects from finding the stone to the final product. Also plenty of time to answer all questions. Really cool. Super interesting. In short, a REAL RECOMMENDATION (Original) Fantastische gebouwen en locatie. Een gratis rondleiding gekregen die super interessant is. Ze nemen alle tijd om alle facetten van het vinden van de steen tot eindproduct te bespreken. Ook alle tijd om te antwoorden op alle vragen. Echt te gek. Super interessant. Kortom een ECHTE AANRADER

(Translated by Google) Received by a lovely lady who showed us everything about diamond cutting with a lot of passion. The highlight was the viewing of the various beautiful gemstones. (Original) Ontvangt door een alleraardigste dame die ons met veel passie alles liet zien over het slijpen van diamanten. Hoogtepunt was het bekijken van de diverse prachtige edelstenen.

(Translated by Google) Special place, worth visiting. (Original) Especial lugar, vale la pena visitarlo.

(Translated by Google) Lots of time and attention. Very clear information. Very friendly and tells with passion. (Original) Heel veel tijd en aandacht. Zeer duidelijke informatie. Bijzonder vriendelijk en vertelt met passie.

(Translated by Google) I had seen a beautiful pendant for a chain (solitary) abroad. I searched an example over the internet and emailed it to Coster. The pendant has been put together completely for me. Communication went very smoothly and during our visit to Coster we were given a short tour of the diamond cutting shop. We have been well served. I have a beautiful necklace, just as I imagined it. (Original) Ik had een mooie hanger voor aan een ketting (solitair) in het buitenland gezien. Ik heb een voorbeeld via internet gezocht en deze naar Coster gemaild. De hanger is volledig voor mij samengesteld. De communicatie is erg prettig verlopen en we hebben bij ons bezoek aan Coster een korte rondleiding gekregen in de diamantslijperij. We zijn goed geholpen. Ik heb een prachtige ketting, precies zoals ik het me had voorgesteld.

(Translated by Google) Very interesting (Original) Erg interessant

Nice place

(Translated by Google) Explanation was brief !! Beautiful objects, but the presentation is simple. The ambiance of the characteristic buildings was also not recognizable from the inside. Disappointed and not worth repeating .... (Original) Uitleg was summier!! Mooie objecten, maar de presentatie is simpel. Ook de ambiance van de karakteristieke gebouwen was niet herkenbaar van binnen. Teleurgesteld en niet voor herhaling vatbaar....

(Translated by Google) The tour is very much focused on sales. (Original) Rondleiding is wel heel erg op verkoop gericht.

(Translated by Google) Beautiful diamonds. (Original) Mooie diamanten.

Very nice guide Esther, answered all our questions

Amazing Royal 201 collection ❣️

Free, welcoming. Didn't force you to buy anything. Hadn't booked but they fitted us in. Informative, interesting and a nice way to spend an hour, especially as museums opposite were almost 20 euros per person per museum

Is nice to visit the diamond factory outlet in Amsterdam. We had learned a lot of knowledge regarding the grade & cutting of the diamond.

If you have a spare thirty minutes and even the slight interest in how diamonds are prepared then their free tour is a worthwhile and educational opportunity. Although a jewellery shop there was no big sales push and they made anyone feel welcome. On the ground floor there’s the opportunity to see raw diamonds being prepared and polished and the tour guide gives a good description of the different cuts which result. The craftsmen, although working behind glass, are close enough to get a detailed look at the activity and they are happy to answer questions. Upstairs the guide gave an opportunity to admire the finished products up close and personal, with more lessons regarding what to look for when purchasing a diamond, The overview was kept both entertaining as well as educational and its a welcome environment to ask questions if you wish. At the end of the tour there’s an extensive shop, selling everything from high end jewellery to souvenirs. Again, there’s no pressure for any form of purchase which is nice but there’s lots of further opportunities to admire the products. Given the tour is offered free, for anyone who’s interested it’d be daft not to tag along. They’re offered regularly throughout every day and even an expert can learn something. The tour guides are knowledgeable and it’s insightful. You could be in any city across the world but given the central location it makes sense while you’re here!

I would highly recommend getting your diamond ring in Coster Diamonds in Amsterdam . I have had two dealings with them . One I picked out my ring in person and another was online when viewing it from Ireland . My first experience was initially getting a ring . They have a huge selection of diamonds an amazing diamond factory . It was a very enjoyable experience picking out my ring they fitted it on the day. My second experience was from Ireland and completely via email / what app messaging . I would especially like to thank Danielle who my partner and I dealt with at Coster . We are living in Ireland and ordered a new ring with the help of Danielle . She was always so quick with replies sending videos / picture via what app or email . She Showed us a variety of rings in different settings and really made the experience enjoyable . I must say she was super efficient with getting it delivered also, it took less than 24hours to arrive with the GIA cert and lovely presentation . Thank you very much a Danielle . I would definitely get other Jewelery from this shop again. All the best C & E

Their jewellery collection is beyond amazing! Besides that, the service staff is professional and very friendly. Definitely recommending this place.

The diamond collection here is great, maybe just for the super rich, but also an experience for everyone to have dreams... the sales staff is very enthusiastic, can speak many foreign language for groups of tourists from all over the world.

(Translated by Google) Simply breathlessly beautiful jewelry. Are there once a year. The museum and the tour is highly recommended. Every time I am in Amsterdam I have my rings, which I of course bought there, polished to a high gloss. (Original) Einfach atemlos schöner Schmuck. Sind jedes Jahr ein mal dort. Das Museum und die Führung ist sehr empfehlenswert. Jedes mal wenn ich in Amsterdam bin lasse ich dort meine Ringe, die ich natürlich dort erworben habe, auf hochglanz polieren.

(Translated by Google) You go on a visit and you sell diamonds such as black street (Original) Vas a una visita y te venden los diamantes como los negros esos de la calle

(Translated by Google) Very good. (Original) Muito bom.

(Translated by Google) Excellent place to know how diamonds are full (Original) Excelente lugar para conocer como.pulen los diamantes

The diamonds here are amazing

I had a nice chat with an employee that really helped me. We talked over WhatsApp and even if the necklace I asked about wasn't from Costers I still am very grateful for the help. Really nice people there, can recommend the whatsapp contact.

(Translated by Google) A free museum diamonds. They tell you how they are made and you can see jewelers working. They have very simpatico Spanish guide teaches you very kindly to the inside. Yes to the end is all diamond shop prohibitively expensive for most mortals. Worth seeing as a curiosity. (Original) Un museo gratis de diamantes. Te cuentan cómo se hacen y puedes ver a los joyeros trabajando. Tienen guía en Español muy simpatico que te lo enseña muy amablemente al entrar. Eso sí al final es todo una tienda de diamantes con precios prohibitivos para la mayoría de los mortales. Merece la pena verlo como curiosidad.

👍🏻

(Translated by Google) Interesting, informative. You really see the work of the masters, you begin to understand the difference in diamonds. Although, perhaps this is not what you need. Beautiful things always attract. (Original) Интересно, познавательно. Реально видишь работу мастеров, начинаешь понимать разницу в бриллиантах. Хотя, возможно, это тебе и ни к чему. Красивые вещи всегда притягивают.

(Translated by Google) Good product (Original) Sản phẩm tốt

O.k but not as good as tours in South Africa. The salesperson spoke about the 4Cs and we watched a cutter and polisher doing little work behind glass screen. It wasn't long before we were shown the jewellery on sale. My brother really enjoyed his first diamond tour.

(Translated by Google) Enthusiastic seller, acceptable prices (Original) Người bán nhiệt tình, giá cả chấp nhận được

(Translated by Google) Learning how to cut diamonds (Original) Do aprendizado de lapidação de diamantes

What a great place , informative and friendly and our guide Ilkham was a “diamond” :)

(Translated by Google) They took us on an "excursion" with MASEUROPA, I would have preferred to stay outside. I do not understand the grace of buying a tiny pebble that is worth fortune, for more insights that give about the types of cut, points and color are making money with mining. (Original) Nos llevaron de "excursión" con MASEUROPA, hubiera preferido quedarme afuera. No entiendo la gracia de comprar una piedrita diminuta que vale fortuna, por más esplicaciones que den sobre los tipos de corte, puntos y color están lucrando con la minería.

They sell good diamonds

(Translated by Google) Select place, explanation in our language, and accessible prices. Unrivaled quality It makes you want to come back for more. (Original) Lugar selecto, explicación en nuestro idioma, y precios accesibles. Calidad inigualable. Deja ganas de regresar a por más.

(Translated by Google) If you want a beautiful jewel visit this place. Beautiful things at your fingertips. (Original) Si quieres una hermosa joya visita este lugar. Cosas hermosas al alcance de todo bolsillo.

If you go to royal coster you will know is the best for the world

(Translated by Google) it is very nice diamond factory, which you can see how diamonds be cutted. (Original) it is very nice diamond factory, which you can see how diamonds be cutted. 很好的钻石工厂。

(Translated by Google) Interesting (Original) Interessante

We got free access to this, I’m happy it was free. The tour was pointless. The tour guide spoke quietly in a loud environment, and kept walking off and leaving us, so we ended up giving up on the tour entirely. We got the impression that he didn’t want to engage with us if we weren’t going to make a purchase. Little did our guide know, I actually wanted to purchase a ring. But I didn’t, because of how we were treated. I wouldn’t recommend visiting here at all. Bitterly disappointed.
