Pauline has made an interesting and engaging report on the work and its origin. A recommendation. Her story makes this visit extra fun and interesting.
Pauline is a great storyteller and very passionate about her job!
Simone explained everything to us with great detail and kindness. We were able to see real examples of diamonds to better understand the differences that make them unique. Simone was a great host and the tour was a fantastic experience, highly recommended.
Pauline was super helpful and talked through the whole cutting/polishing work. She was really accomodating and posed for a picture with us and her Guiness World Record certificate for polishing the World's smallest Diamond in 1994 (record still held today). Really insightful tour with audio guides included.
Very pleasant experience; I would have added a few more explanations about diamond processing.
Fabulous experience! Fabian taught us a lot about diamonds and how cutters shape them. We were able to examine and try some beautiful ones. We were spoiled!!
Angela was so knowledgeable and made the whole experience memorable, we loved it. My friend even bought a diamond ring for her daughter
We did the tour with Simone Pilla; very interesting experience with exceptionally helpful and competent guide. We will also suggest your “boutique” to friends for purchases.
Verry good to visit. Don’t regret it. Recomend to visit. Royal coaster diamond is the best museum from Amsterdam. Good time
