Obsidian is a naturally occurring volcanic glass formed in swiftly cooling lava that has a high silica content. It is not considered a true mineral, as it does not have a consistent chemical content and it does not form crystals. Obsidian is commonly found within the margins of the lava flows known as obsidian flows. It has a glassy texture and a glass like luster. The color in Obsidian varies, depending on impurities in the parent lava formation. The various shades of Obsidian include black, rainbow, snowflake, gold, and mahogany. Obsidian is hard and brittle and was commonly used for tools.
Snowflake Obsidian is a natural volcanic glass containing the mineral Cristobalite in the form of white "snowflake" crystal patterns. Snowflake obsidian forms in areas of past or present volcanic activity. These areas lie along the tectonic plate boundaries. It is found in many areas of the world where volcanic activity has taken place, including West Coast of the United States. It is also found in Italy, Brazil, Scotland, and Argentina.
