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.

Olivine is a group including among others Fosterite, Dunilite and the gem var. of forsterite commonly named Peridot. The collection brings together peridot from different locations, among them one of the rarest and most amazing gem ever, an extremely rare pallasite peridot with iridescent inclusions from the Jepara meteorite. The Dunilite comes from the discoverer of the specie’s own collection.
