Snowflake obsidian [snoh-fleyk|uhb-sid-ee-uhn]
Obsidian is naturally occurring glass produced by a volcano, and is naturally black due to its iron and magnesium content. The white spots that make the obsidian "snowflake obsidian" are caused by clustered crystals of cristobalite, a morphed form of quartz cause by the high temperature of a volcano.
