Perovskite (classic material) (ex Kay Robertson Collection)

Item Description

There are dozens of localities for Perovskite in Italy, and this particular specimen is from the lesser known Rocca Castellaccio locality. This miniature specimen features a 6 mm, sharp, well-formed, orange-brown colored pseudo-cubic (orthorhombic) crystal of Perovskite sitting on white Calcite with minor greenish colored Clinochlore on host rock matrix. The Perovskite is in good shape, though it's not 100% complete. An additional crystal of Perovskite can be seen on the side of the piece. A lot of Perovskite crystals are a dark grey or black hue, so to have a crystal with a lighter color and a bit of internal translucency is certainly desirable. Ex Kay Robertson Collection (#9257). Kay was a prominent California collector, who specialized in European classics. She nearly lived 100 years from April 1920 - March 2020.
