One copper electroformed Golden Sheen Obsidian Etched Yin Yang Cat complete on an 18” soldered gunmetal chain. Photos do not do these stones justice. The permanent etched Yin Yang cats are phenomenal. Obsidian is a naturally occurring volcanic glass formed in swiftly cooling lava that has a high silica content. The reflective nature of Obsidian makes it one of the first stones used in self-reflective meditation, internal growth and self understanding. Its color is a striking combination of gold and black, making it extremely unique and beautiful. Stones measure 1.0”. Size, shape, color and pattern may vary as no two stones are alike.
