Going way back miners at the classic Bisbee locality preserved specimens of the huge variety of calcite found within the mines, as they had no commercial value, but the miners recognized their beauty and variety. This specimen came out of the collection of Dave Stoudt, who had quite a broad array of Bisbee calcites in his collection. This is a stalactitic form of sharp rhombs, with a color tint from inclusions of hematite.
