Calcite, Fluorite
Cabinet, 10.8 x 5.6 x 3.4 cm
Santa Eulalia District, Mun. de Aquiles Serdan, Chihuahua, Mexico
You may be familiar with these spiky calcites from Santa Eulalia; but here, they are in a rare association with sharp cubes of colorless fluorite, as well as a later generation of tiny, sparkly, gemmy little calcites. Ex. Stoudt Collection.
