"Shades of the Aurora Borealis". Rainbow Obsidian pendant with chain.
This large (2" x 1 1/4") Rainbow obsidian pendant shows flashes of green, purple and pink as it plays with the light. Obsidian is more a volcanic glass than a stone. It occurs as lava cools too quickly for the minerals to re-crystallize. The overall drop of the piece is 3", wrapped in Sterling Silver and hangs on a silver chain.
