The "normal" Smoky is an impressive 3.8 cm, translucent, sitting beautifully on a large Feldspar crystal. What makes this truly unique are the rest of the Smokies. They are in two sets of 2 cm crystals, one set 6 cm long, the other 2 cm. The crystals are incredibly intergrown, resembling a spine. I am not sure if these are a series of Japan Law twins, intergrown Gwindels, or what. On top of that, literally, you have Hyalite Opal adding incredible accent to the piece. Ex. Charlie Key.
