Really good experience. We enjoyed the intimate tour and came away with two items from the sale. Helped me out with a fifty year wedding anniversary gift for my lovely wife.
Excellent experience, Angela was an incredibly knowledgable, patient, friendly & helpful guide. Definitely worth booking! The length of the visit extended beyond the allocated time, which was perfect for us as we wanted the full experience. Beautiful atmosphere and stunning buildings.
Had a great tour, Sang was a fantastic guide. We learnt so much and had fun looking at the diamonds and jewellery. We did buy but there was no pressure to buy.
Sang was a great guide. So much information and beautiful diamonds.
Sang was very good!! Great explanation of the differences in the diamonds and their grades
My family and I spent 2 beautiful hours at this facility because we discovered a unique reality, that is, regarding the processing of diamonds, and above all we thank the employee Mr. Anas Salama for his professionalism, availability and illustration of the product.
The Royal Coster Diamond Experience was a wonderful and excellent experience that I and my sister would highly recommend. My sister wanted to do a diamond tour and I went back and forth as to where to do the tour and then what type of tour. We were actually able to do a tour with Royal Coster and another diamond center during our trip. If I had to choose one, I would recommend Royal Coster. Our guide, Hans, was very knowledgeable about diamonds and had an excellent personality for showing the factory and the diamonds. The tour is not a long tour but it is very interesting and truthfully we wanted to see the diamonds! With the Royal Coster Diamond Experience we were given an individual tour, and a gift bag. We then were able to see the diamonds - loose diamonds were brought out and shown to us. We were then able to shop in the store and try on jewelry. My sister ended up purchasing a ring and they bent over backwards to ensure that the ring was sized appropriately and that we had all of the necessary paperwork. It was one of the highlights of our trip.
Impressive and interesting tour with many detailed explanations about diamonds and the cutting of them.
This was a great experience to learn about diamonds , their natural creation, polishing and get a much better understanding of diamond quality , polishing and the charisma of these gem stones. Additionally you get to learn about the history and legacy of Royal Coster and an overview of the diamond industry. Our guide was excellent , knowledgeable , friendly and fun, easy to talk to and discuss every aspect of diamonds. Finally there is a small museum that you can view at you leisure.
Excellent visit by Fabien, very informative and exciting. I recommend it :)
