Chrysoberyl (un-twinned crystal) (ex Rich Kosnar Collection)

Item Description

Here we have a lovely, gem quality, greenish-gold colored crystal of Chrysoberyl from the Colatina locality at Espírito Santo, Brazil. In reflected light, the crystal almost appears as though it were opaque, but with backlighting, you can see the beautiful internal optic quality. this is indeed a single (un-twinned) crystal, which is a notablet rarity, as the vast majority of the chrysoberyls from Espírito Santo show some kind of twinning habit. A really attractive toenail specimen of this classic material with an uncommon crystal habit and color (most Chrysoberyls from this area show some kind of green hue, but this one is notably on the golden side of the spectrum. The piece dates back to the early 1970s and comes from the collection of well known mineral dealer and collector Richard A. Kosnar, who personally acquired it in Brazil. Valued at $1,250.
