Mina Aurora, Charcas, San Luis Potosi, Mexico
Small, white colored, dogtooth Calcite crystals cover much of a cluster of Datolite crystals and the Chalcopyrite and Pyrite crystals which rest on the surface of the Datolite. The Calcite fluoresces a pink/orange color under SW UV. The Datolite crystals are a light green color. Where not covered with Calcite, the surface of the Datolite crystals can be seen to be very smooth with a high luster.
Flaws: A few of the Calcite crystals are damaged. Some of the Chalcopyrite crystals are incomplete
