Peanut Obsidian Slab 19

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.  Origin:  Mexico Dimensions:  5" x 4.5" and approximately 9.3 mm thick.  Weight = 248 grams.  Shown wet.  Not polished.  Flaws are shown as white lines in the final picture frame.
