TriFlow Mahogany Obsidian Slab! Lapidary Stone Slab! Thunder Egg Please note that measurementsTri Flow Obsidian comes from Glass Butte Oregon, and is a gorgeous form of mahogany obsidian that often has multiple grains and currents of flow! Tri Flow can make some designer grade cabochons, as the obsidian between is often pure and almost completely see through when held to light or cut thin enough, and the waves of pattern are often in layers! The color generally comes from Magnetite that was present in the lava flow! Tri Flow Obsidian is
