Golden sheen obsidian is volcanic glass, naturally formed when volcanic lava cools quickly. Air bubbles are periodically trapped inside the layers during the cooling process, creating a highly desired shimmer effect--the golden sheen. This grade A obsidian has a velvety luster and "cat's eye" effect.
