I had a guided tour here, and I found it very interesting to learn about diamond grinding and look at the extensive collection. The staff is very service oriented!

Loved this experience! So interesting to hear and see how the diamonds are cut. To view diamonds worth thousands and then look at jewellery pieces to buy. Absolutely no hard selling went on though which was refreshing!
