Small Cabinet, 9.3 x 7.34 x 3.6 cm
For some time, "Endlichite" was considered a species, but is now classified as an Arsenic-bearing variety of Vanadinite. This lovely specimen hosts hundreds of classic, silvery, almost metallic looking, thin prismatic crystals of "Endlichite" on rhombohedral Calcite matrix. The "Endlichite" crystals have a light curve to them, which is very distinctive for this mine. A very graceful specimen, and virtually damage free on the display side. Ex. Brian Kosnar Collection.
