Excellent. Danielle truly understands what good customer service is all about. I am super happy with the way I have been treated.

Excellent!

I have placed three orders with Royal Coster Diamonds (two rings and one pair of earrings), and every experience has been flawless. The quality and craftsmanship of the jewelry are exceptional, and each piece has met my expectations perfectly. From the very beginning until the final delivery, Daniëlle has been my personal Diamond Consultant and has provided outstanding service throughout the entire process. She is professional, attentive, and extremely reliable, always responding promptly and taking the time to answer all questions in detail. Her guidance made every step feel effortless and reassuring. Thanks to this consistently excellent service and the beautiful pieces from Royal Coster Diamonds, each purchase has been a truly positive experience. I would gladly return for future purchases and can speak very highly of both the service and the jewelry.

Royal Coster Diamonds is a well established reputable place to purchase high quality jewelry. I purchased my wife's engagement ring and wedding band at the Royal Coster facility while on vacation in Amsterdam. Now I purchased a gift for our anniversary. I have full confidence and trust in the merchandise sold by Royal Coster Diamonds. Their items are the highest quality and the settings are exquisite. I have been dealing with Danielle for years now and she is a real treasure as well as having become a friend. She provides me with excellent options and valuable advice so I can make the right choice when selecting that perfect gift. I would highly recommend Danielle and the entire Royal Coster team - with members like Hans who will do their absolute best to provide you with the highest quality merchandise. I am, and will continue to be a loyal Royal Coster customer.

Highly positive experience. The staff were very friendly, courteous, and knowledgeable. We also appreciated the small champagne bottle being opened after our purchase. Thank you!

Perfect experience under consultancy of Mr. Anar. This is our second time of visit and shop and this time we came back for good brand Royal Coster and primarily to see Mr Anar and his warm and professional hospitality. We are eager to see Mr. Anar again in future. It was a pleasure us shopping with his specialised approach and also close friendship.

I am extremely happy with everything ! The craftsmanship and quality are outstanding, the earrings are stunning ! And the service... And a special mention to Nenad Popović who provided outstanding customer care. He was incredibly helpful, professional, patient, knowledgeable and kind, making the whole process easy and enjoyable. I couldn’t be happier with my purchase. A wonderful experience from start to finish.

My experience was truly wonderful. The staff makes you feel welcome and well taken care of. They were patient and knowledgeable and took the time to explain details to help me choose, which made the process reassuring. The quality of the pieces are exceptional.

Great products and prices, but so far charged us for VAT tax that we were assured would be refunded and it has not been!

Good Experience!

I recently saw a beautiful watch by Frederic Constant offered on the Coster Diamant website. After paying, I was able to pick it up quickly and received a friendly welcome in Amsterdam.
