Gemstones

To determine gemstones quality, you could take as a basis the “4 C’s”diamonds grading sytem. It relies on four major criteria : color, cut clarity and carat (weight). To judge the quality of other gemstones, you need to add a fifth “C” : the country of origin. Beside the fact that Alpine minerals are rare and often extracted in extreme conditions, only a small part of them are suitable for faceting. That’s what makes our gemstones unique and valuable to any collector or jeweller. Each stone is  the result of an ethical process, from the sourcing to the precision cut, made in Belgium, France and Switzerland.
