Snowflake Obsidian

This is snowflake obsidian. Obsidian isn't actually a crystal or a mineral; because it doesn't have an internal lattice structure, it's actually classified as a mineraloid. It is an igneous rock formed from the rapid cooling of lava. In other words, it's volcanic class. The snowflake pattern comes from partial crystallization of the glass that forms a mineral called cristobalite, which actually does meet the definition of a crystal/mineral (the black part is the mineraloid part). Snowflake obsidian has healing properties. It is an excellent tool for working with both the root and crown chakras. In fact, it connects root to crown and allows energy to flow between them through all your chakras.
