- Cabinet, 15.9 x 15.9 x 13.4 cm
- Santa Eulalia District, Mun. de Aquiles Serdan, Chihuahua, Mexico
A BIG specimen of a type of calcite that came out a long, long time ago from Santa Eulalia and has hence been unavailable - until a recent find. These calcites are instantly recognizable by their strange form: an earlier generation of dark, opaque, hematite-included scalenohedral crystals seeming to emerge from within a later generation of translucent crystals of a lighter color.
