Calcite on Fluorite

Prismatic “poker chip” calcites to 2cm populate a knob of bi-colored fluorite. A two sided specimen as the dominant fluorite side shows smaller more elongated prisms while the calcite side has the larger sandwich type short prism crystals. The poker chip at the very top has a cleave. From my personal collection, I acquired it in 2001 when mine localities from China simply were not stated.

Locality: Hunan Province China

Composition: Calcium Carbonate and Calcium Fluoride
