Pezzottaite: The mineral pezzottaite information and pictures

About

Pezzottaite is a mineral that is very similar to Beryl, but it contains lithium as well as the rare element cesium replacing some beryllium in its chemical structure. It is therefore scientifically classified as a separate mineral species from Beryl.

When first found, it was though to be a variety of Beryl, but it wasn't until 2003 that the IMA regarded Pezzottaite as a unique mineral species. It is named after Italian geologist Dr. Federico Pezzotta of Milan.

Noteworthy Localities

Pezzottaite is a relatively recent mineral in terms of its discovery. The most significant locality for Pezzottaite, where this mineral was first described, is the Sakavalana Mine, Ambatovita, Fianarantsoa Province, Madagascar. Additional localities are reported to have yielded Pezzottaite since 2006, including the Deva Mine in Konar, and the Parun Pegmatite Field, both in Nuristan, Afghanistan. Another discovery of Pezzottaite from Burma made its way to the market in 2006, with specimens coming from the Paleini Mine, Khetchel Village, Momeik, in the Mogok area.
