Taaffeite

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 Taaffeite groupe contains three members: ferrotaaffeite-6N’3S or Perhmanite, magnesiotaaffeite-2N’2S or Taaffeite and magnesiotaaffeite-6N’3S names Musgravite. Perhmanite exists only as microscopic crystals. Taaffeite and Musgravite are two of the ultra rare gems on Earth, distinguished only by presence of magnesium for the second. Musgravite (lab tested) is the rarest. The Taaffeite can also be easyly be misidentified as Spinel. The collection includes one lab tested purple taaffeite crystal from Sri Lanka and a colourless Musgravite from Myanmar, with graphite inclusions. This gem was intensively tested by GIA and featured in their famous magazine Gems & Gemmology, Vol 49 2013!
