Description
Sometimes called "cave calcite," this aragonite comes from the Potosi Mine in the Santa Eulalia Mining District, Chihuahua, Mexico. The silver, lead, zinc and copper ores in this mine are associated with thick-bedded limestones overlain by a series of rhyolite flows and tuffs.
Cave calcite forms underground due to groundwater deposition. While it often forms stalactites and stalagmites it can also form unique, branching, tree-like structures. These beautiful formations are sometimes known as 'floss ferri' (flowers of iron) and frostwork.
This Cave calcite or Aragonite specimen is in remarkable condition exhibiting the classic tree-branch like crystal structures covered in sparking crystals.
