Taaffeite

Oxide mineral

Taaffeite (/ˈtɑːfaɪt/; BeMgAl4O8) is a mineral, named after its discoverer Richard Taaffe (1898–1967) who found the first sample, a cut and polished gem , in October 1945 in a jeweler's shop in Dublin As such, it is the only gemstone to have been initially identified from a faceted stone. Most pieces of the gem, prior to Taaffe, had been misidentified as spinel. For many years afterwards, it was known only in a few samples, and it is still one of the rarest gemstone minerals

Since 2002, the International Mineralogical Association -approved name for taaffeite as a mineral is magnesiotaaffeite-2N'2S.
