This is a 1.1-kilo single, euhedral crystal of the rare species Petalite! Shockingly, it is even a floater, complete all around (though several faces are less well developed, all are present). I have never imagined such a large Petalite and surviving un-etched by later dissolution in the pocket as so many are. This is the largest complete crystal, in fact, that I know of - aside from the fact that it is of high quality. The whole crystal is translucent when backlit. It is a MAJOR display-quality rarity worthy of a major museum or private collection, representing a shocking order of magnitude size difference compared to what you would expect for a sharp Petalite normally (crystals 100-150 grams are normally considered large from other locales). This was mined, apparently, around October of 2008. It is hard to photograph because it has such soft reflectivity, and is so large. It is quite a bit better, in person.
