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 unetched 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 wha tyou 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.
