Sphalerite (twinned?)

Item Description

Bizarre, most unusual hoppered cluster of metallic silver-black Sphalerite....that when hit with very strong light, shows green highlights on the edges. The outer rim of the specimen appears to be the faces of two large crystals, and the sunken interior (on both ends) morphs into individual crystals. The faces of these crystals are sharp and lustrous, and nestled among them is one classic, gemmy yellow-green Sphalerite. Quite an aesthetic, and in it's own way, extraordinary, miniature. It LOOKS like a Chinese bournonite!
