Obsidian, a dark volcanic glass. It forms when lava cools quickly. It has been used for tool making since 21,000 B.C American Indians used it for arrowheads, and the Aztecs used it for sacrificial knives and mirrors. Today, it is used for dating; the stone weathers slowly at a uniform rate, and the thickness of the weathered layer is measured microscopically and gauged against known standards to give a date in years.
Snowflake obsidian has the property of bringing things to the surface. The things brought to the surface could be positive or negative, love, anger, secrets; but with snowflake obsidian, these things are brought to the surface more gently that they might be otherwise. Snowflake obsidian can provide balance during times of change. It aids in seeing patterns in life and recreating them in a more beneficial way. It is a stone of serenity and purity, and can shield against negativity. It is associated with the root chakra and is said to be beneficial for the veins, skeleton, and smooth skin. Note that healing crystal meanings are spiritual supports to healing and are not prescriptions or healthcare information. Snowflake obsidian is used for protection from physical and emotional harm.
