Dear Royal Coster Diamonds Team, Thank you very much for your excellent service and support throughout my purchase. I am very satisfied with my experience. I especially appreciate the professional and attentive way you handled my requests, including the additional inspection of the watch, the rechargeable battery and the GPS function before shipping. I also appreciate your efforts to arrange the delivery according to my schedule. Everything was handled professionally and efficiently. I am very happy with my Seiko Astron SSH173J1 and with my purchase from Royal Coster Diamonds. Thank you again for your excellent service. Brilliant regards, Alex Minich

My husband and I stumbled upon this store while walking the streets. We had no idea about the history of Coster until our diamond specialist, Eliana, told us. She also told me that I could personalize a ring if I didn’t find one I loved and they could have it done within 20 minutes! Eliana spent almost 3 hours with us and helped me create the most beautiful ring I’ve ever seen!! I felt so lucky to have been paired up with her. She was so sweet, knowledgeable and such fun to chat with. She is very good at what she does. We are going home to The United States with a great story.

Purchased a watch where the staff were very helpful and friendly throughout the process, was a pleasure to purchase from here and had a great selection of watches which I was very impressed with

We actually wanted to buy a Rolex Lady Datejust at the local Rolex store. I will not describe our shopping experience there in order to avoid being hit with a defamation suit... Fortunately, our experience at Royal Coster was the exact opposite. Ms Angela El Kaid welcomed us warmly, patiently showed us several options from the vast range of Longines watches, advised on their styles and function and how they met the expectations of the recipients. We returned a day later to finalise the purchase and couldn't resist buying a beautiful diamond necklace in addition.

Mijn ervaring is niet de beste geweest, maar ik vind het bedrijf wel fijn – ik heb er mijn trouwringen gekocht, en daarom heb ik er een goed gevoel bij – al ben ik aan de andere kant niet tevreden.
