A one-day introductory workshop on Gemology that will give us the chance to explore the world of diamonds. Diamond, adamas, adamant; the absolute precious stone that represents love, devotion, firmness and dazzling beauty will be the focus of this workshop, which aspires to initiate us into the charming world of this mysterious precious stone. The workshop includes a theoretical part, during which we will talk about the history of diamonds, their technical characteristics – 4Cs: colour, clarity, carat weight, cut – and their processing, as well as about the synthetic diamonds and some myths and truths regarding the “blood diamonds”. The workshop will be concluded with a part of practice, where we will have the chance to work on jewelry with diamonds using special tools in order to identify their technical characteristics.
