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 most famous member of the Beryl group are the emerald and the quamarine. Heliodor, Morganite, Pezzotaite are less known members. The rarest is the red Beryl, it’s only gem source being closed now. A classic enhancement for emeralds and red beryl is oiling. Almost 90-95% or colombian and african emeralds are oiled, but most of emeralds from Swat Valley in Pakistan) are not oiled.
