Comment: Sparkly, drusy calcite on floater portion of large purple fluorite cube. The largest cube portion is 9 cm across. The back side has healed and is covered with tiny crystals of fluorite. The piece is transparent with a strong backlighting, but it is so big it is tough to photograph. A few minor dings, but this is a large specimen from a great defunct locality. (Picture does not do this justice, coating is sparkly silver)

Minerals: Calcite (CaCO₃) Fluorite (CaF₂)
