This is a B-grade XXL sized Rainbow Obsidian tumbled stone from Mexico.
Obsidian is a naturally occurring volcanic glass formed as an extrusive igneous rock. It is produced when felsic lava extruded from a volcano cools rapidly with minimum crystal growth. Rainbow Obsidian occurs when natural gasses are trapped inside the rapidly cooling high viscosity lava and cause a beautiful rainbow play of colors.
Obsidian is commonly found within the margins of rhyolitic lava flows known as obsidian flows, where the chemical composition induces a high viscosity and polymerization degree of the lava. Obsidian is hard and brittle; it therefore fractures with very sharp edges, which were used in the past in cutting and piercing tools, and has been used experimentally as surgical scalpel blades.
The first archaeological evidence known of usage were made from within Kariandusi (Kenya) and other sites of the Acheulian age (beginning 1.5 million years previously) dated 700,000 BC, although the number of objects found at these sites were very low relative to the Neolithic.

Black Obsidian powerfully eliminates negative energies in oneself and one’s environment. It is like a psychic vacuum cleaner, cleansing the auric field of disharmony, negative attachments, astral “junk,” as well as one’s own anger, greed, fear, resentment, etc.
It is a strong grounding stone, stimulating the root chakra to make its connection with the Earthstar chakra below the feet, and deep into the core of the Earth. It is useful for all types of scrying, including spirit communication. It is also a strong stone of spiritual protection. In addition, it helps bring one’s own Shadow material out of exile, allowing it to be transmuted through the heart. It aids in recalling the exiled bits from the unconscious, even from past lives.
This is a great aid to healing the body and the soul.
