Black Obsidian Sphere 20mm

These snowflake obsidian spheres measure 20mm in size. 

Obsidian is a naturally-occurring volcanic glass that can be deep-black to blackish-green in color. In the past, it was used to manufacture cutting and piercing tools, and it was once used experimentally as surgical scalpel blades. Obsidian is thought to aid in balancing energy in the physical body. 

Each piece is similar, though no item at Crystal Joys is exactly the same as every item uses a unique stone that is non-fabricated.  Every item at Crystal Joys is truly "one of a kind". Slight variations in color, size and bead shape exist.
