This is a very attractive specimen of glassy green window panes of torbernite crystals surrounding a few small smoky quartz crystals. I don\'t think the quartz has any chance except to be smoky, as torbernite is somewhat radioactive and this is one way clear quartz winds up smoky. At any rate, this is a very attractive piece, without damage, that probably came out more than 30 years ago. It is 5.5 x 4 x 2.6 cm. Stunning!
