Calcite and scheelite specimen for sale         

Calcite with Scheelite and Fluorite
Hunan province, China

Beautiful cabinet-size display specimen of many sparkling calcite crystals. It is hard to appreciate them unless the specimen is seen in real life where it can be rotated in the light.

 The fluorite crystals are visible with a hand lens.  They do not appear to fluoresce.
