Tri-Flow Obsidian Rough Chunk! Amethyst Lace and can work into someTri 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!
