North America

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.

The collection brings together some of the rarest gems from North America, some of them are great rarities as faceted specimens like the Veszeinite or the bicolor Vesuvianite, or the exceptional large Charlesite.
