Description

Mexican Peanut obsidian was discovered in the 1960s near Alamos, Sonora, Mexico. In recent years it’s become exceedingly scarce as it has been a lapidary favorite for years. Peanut Obsidian is a variety of Perlite and a naturally occurring amorphous volcanic glass. The chatoyant radiating red-orange spheres which make this stone so unique are actually feldspar crystals that have been stained red over time by a coating of Hematite. This material will make stunning finished cabochons.
