Geology / History

Obsidian is an igneous rock that forms when molten rock material cools so rapidly that atoms are unable to arrange themselves into a crystalline structure. The result is a volcanic glass with a smooth uniform texture that breaks with a conchoidal fracture.

As a glass Obsidian is chemically unstable. With the passage of time, some Obsidian begins to crystallize. This process does not happen at a uniform rate throughout the rock. Instead it begins at various locations within the rock. At these locations the crystallization process forms radial clusters of white to white/grey Cristobalite crystal Spherulites within the Obsidian. When cut & polished these specimens show a distinct snowflake like pattern caused by the Spherulites.
