This specimen is a very hefty cluster of intergrown, thick crystals of myriad habits, and on top sits this perfect, isolated "button" of a crystal! The crystal is SHARPLY tetrahexahedral with a dodecahedral modification, and measures almost 2 cm across. It just sits there looking at you, very bizarre to see at the top of this cluster! Ex. Weesleyan College and Neal Yedlin Collections. Comes with custom lucite display base.
