This listing is for a single Snowflake Obsidian flat stone, also known as a pocket stone.
Please note that each piece is unique and may differ slightly in shape, pattern or color from the examples pictured.
Snowflake obsidian is a type of black obsidian with white or grayish spots. These spots are called spherulites, and they are composed of needle-shaped cristobalite, a type of quartz.
Obsidian itself is a naturally occurring volcanic glass formed as an extrusive igneous rock. It is produced when felsic lava extruded from a volcano cools rapidly with minimum crystal growth.
