Spinel

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.

For a long time Spinel was confused for ruby and sapphiresas the famous Black Prince Ruby. One of the famous source is Mogok and the rarest are the cobalt blue spinels from Luc Yeh mine in Vietnam.
