Obsidian is a crystal for protection and spiritual purification. Obsidian is a powerful material for reflection, as it amplifies psychic abilities. Obsidian is a great stone to use when deep in meditation, as it will allow you to see things more clearly. It can be helpful when reflecting on your own actions, as well as reflecting on a situation.
More about the crystal:
Obsidian is not a crystal, and instead is considered a natural, volcanic glass. Obsidian is formed from lava rock, and as it cools, gas bubbles can rise in the material. These bubbles can create patterns and colors within the obsidian. This is how golden, silver, and rainbow obsidian form.
