Tourmaline

This collection presents mostly « rare gems » or « collector gems », more often not used in jewellery because of rarity or hardness. Rarity is due to  the quantity available, or a rare color, source or inclusion, or the difficulty to cut the rough into a faceted gem. Microphotographies are taken with an old Olympus microscope and an iphone. These gems are not for sale, but some extra specimens may be available. The collection is visible but stored in a specific location, so please contact me for an appointment.

Tourmaline is one of the most famous semi-precious gem in  the world. The variety of colors is stunning. Some are very common as the black Schorl, but some varieties are highly prized by jewellery, some other come from only one source and are very scarse. The collection brings together some of the rarest members as Vanadium and Uambara dravite, the cuprian Paraiba and the Fluor-Lidicoatite.
