Tri-Flow Obsidian Rough Chunk! Cretaceous I did make the mistakeTri Flow Obsidian comes from Glass Butte Oregon, and is a gorgeous form of mahogany obsidian that often has multiple grains and currents of flow!

The color generally comes from Magnetite that was present in the lava flow! Tri Flow Obsidian is
