Rainbow obsidian engraved flower entirely hand engraved.

Rainbow obsidian is one of the milder types, but with powerful protective properties. It absorbs negative energy from the aura and removes stress from the body. It replenishes the energy of the heart and cuts bonds of old love. You get to know your spiritual nature through it. The color of obsidian varies quite dramatically depending on the contaminants it contains. The color is usually dark green to deep black, although granite with a similar composition is a light-colored material. This is usually caused by particularly finely divided hematite or magnetite. Snowflake obsidian contains inclusions of spherically grown structures, mostly of feldspar or cristobalite, called spherulites. They arise from spherical crystal growth from a single central growth core. Obsidian is a metastable material that reverts to its crystalline, more stable form over the long term. Volcanic glass is therefore not known from the Paleozoic and Precambrian. In the Stone Age, obsidian was a coveted raw material because it forms razor-sharp cutting edges. It was used for knives and weapons.[source?] Nowadays it is a popular material for art objects and is also used as a semi-precious stone in jewelry. It is then cut as if it were a crystal.
