A single strange crystal of this material turned up with a friend at the Munich show, where I bought it just to have such a bizarre thing. A preliminary analysis by Dr. Federico Pezzotta showed it to be tourmaline, as advertised - and probably a Uvite Tourmaline crystal though this was not determined at the time. However, it is a very weird tourmaline, that looks more like an apatite and has the slickest, glassiest luster you can imagine. It is transparent in zones, and just sparkles. The crystal is fat and complete, 16 grams. I have never seen another like it. The attribution of location was from the source at Munich show (Dr. Pezzotta, who had gotten it from one of his own academic sources). Found in 2010. Joe Budd photos
