- Calcite, Hematite
- Cabinet, 11.3 x 7.0 x 4.2 cm
- Santa Eulalia District, Mun. de Aquiles Serdan, Chihuahua, Mexico
We have lately been featuring some very unusual specimens from the old Santa Eulalia mining area, and this is no exception: a branching, floater cluster of translucent calcite crystals richly included with hematite, which gives them their color. The calcites are complex compound crystals, growing out from a central area in roughly a V pattern.
