Description
Rainbow obsidian is one of the milder varieties, yet possesses powerful protective properties. It absorbs negative energy from the aura and removes stress from the body. It replenishes the heart's energy and cuts ties of old love. Through it, you become aware of your spiritual nature. The color of obsidian varies considerably, depending on the impurities it contains. It is usually dark green to deep black, although granite with a similar composition is a light-colored material. This is usually caused by very finely divided hematite or magnetite. Snowflake obsidian contains inclusions of spherically grown structures, usually of feldspar or cristobalite, called spherulites. These are formed by spherical crystal growth from a single central nucleus. Obsidian is a metastable material that, over time, reverts to its crystalline, more stable form. Volcanic glass is therefore unknown from the Paleozoic and Precambrian eras. In the Stone Age, obsidian was a coveted raw material because it formed razor-sharp cutting edges. It was used for knives and weapons.[citation needed] Today, it is a popular material for art and is also used as a semiprecious stone in jewelry. It is then cut as if it were a crystal.
