Rainbow Obsidian`

This is a AAA Grade Rainbow Obsidian from California.  You've seen those amazing Rainbow Obsidian carvings, spheres, cabochons, knives, arrowheads, and jewelry pieces on the market, most of which have been produced from lesser quality material than this.  Here is your chance to get your hands on some serious, high-quality, rough material. This piece has a purple/green sheen. Notoriously hard to photograph. (3.5"x2"/4.2 oz./8mm thk) perfect cutter
