Learn the secrets of diamonds with the expert geologist Guillermo Martorell. He and his team are at your service to offer you a guided tour and tell you everything you need to know about the origin of diamonds. You will learn about carats, colours, clarity and cuts. In this space they have a craft workshop where they make all their jewellery, and you will be able to see the mastery of their gem-setter as he places a diamond on the rings of the attendees. You can also design your own jewel as a complementary activity.
