This is a huge Taaffeite crystal for the species measuring two and half inches in maximum dimension! Taafetite is an incredibly rare species that almost never turn up for sale. This big yellowish green, translucent crystal is nearly complete and has a mass of 86 grams which is among the largest that we're aware of! It is moderately well formed with several crystal faces and a few sharp edges; it is contacted at the base and on one side. It also fluoresces yellow in both short and long wave UV. As reported by Wikipedia and by anecdote: "Taaffeite is a mineral, named after its discoverer Richard Taaffe who found the first sample, a cut and polished gem, in October 1945 in a jeweler's shop in Dublin, Ireland. As such, it is the only gemstone to have been initially identified from a faceted stone." The currently accepted IMA name is Magnesiotaaffeite and this super rare gem species is a magnesium-aluminum-beryllium oxide! This monster crystal for the species is one of the real prizes hiding in the 1000 piece Larson Burma collection, assembled over dozens of trips and 3 decades of travel to Myanmar prior to 2008. While not the most gemmy, this is translucent and may be the largest complete known crystal of the rare species.
