excellent

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.

Het was weer helemaal geweldig. Twee jaar geleden heeft Daniëlle me begeleid bij de aankoop van een regenboog ring. Deze keer hielp ze mij bij de aanschaf van bijpassende oorbellen. Ze is vriendelijk, denkt mee en reageert snel. Kortom, een parel om in ere te houden!

Magnific

The necklace I ordered wasn't quite what I was looking for. Customer service offered a return and provided a full refund, including the shipping costs. It’s a pity it didn’t work out this time, but kudos to Coster for the excellent way they handled this.

As usual, it was pleasant. From reception till exit, the staff were nice and helpful. The attending sales person, Simon, was very patient and informative about what to buy. Happy customer here.

Good experience

Smooth, fast transaction. Beautiful, well-crafted jewellery
