Snowflake Obsidian is natural volcanic Obsidian which contains a mineral called Cristobalite that displays as the white "snowflake" like patterns we see here! Above the 13x18mm Snowflake Obsidian ovals we see hand carved 12mm Onyx Flowers with sterling sliver bead centers. The entire earring measures 2" long and has a latching back. They were designed by Marianna and Richard and handcrafted by the Artisans of Bali!
