Snowflake Obsidian

Snowflake Obsidian, also known as Flowering Obsidian and Spherulitic Obsidian, is natural volcanic glass containing white 'snowflake' crystal patterns of the mineral cristobalite, due to partial crystallization of the glass.

Since Obsidian is a natural glass these tumbles may have razor-sharp edges that can easily cut skin and flesh if broken. Handle with care. Do not grind dry since long-term exposure to finely ground powder may lead to silicosis.
