This nice specimen of kyanite is in the shape of a large "V". The crystals are long, gernally light blue and translucent, but the best crystal (at the inside of the "V") is impressively blue and transparent. The blue of the kyanite contrasts nicely with the colorless to white host rock (it looks like quartz), most of which has been removed. There is also several crystals of a black mineral with a high luster and some red flashes that uggest to me that it is likely sphalerite.
