Obsidian is a natural volcanic glass formed from molten lava that has cooled very rapidly. Obsidian is an igneous rock that forms when molten rock material cools so rapidly that atoms are unable to arrange themselves into a crystalline structure. It is an amorphous material known as a "mineraloid." The result is a volcanic glass with a smooth uniform texture that breaks with a conchoidal fracture. It is a grounding stone that provides an instant connection from the Root Chakra deep into the core of the Earth. Obsidian helps to clean and remove negative energies and assists in releasing emotions that cause negative energy such as anger, fear, jealousy and greed.
