Mineral: Fluorite
Locality: Peñas Blancas Mine, Municipio San Pablo de Borbur, Western Emerald Belt, Boyacá Department, Colombia
Description: Colorless frosted cubic fluorite crystals with prominent green color centers within the corners. As this is an emerald mine, I assume the green color is caused by chromium. 4.6 x 4.8 cm.
