This listing is for ONE crystal of your choice.
Black obsidian is a volcanic glass that is formed when lava rapidly cools with minimal crystal interference. This would look perfect on your altar, wrapped in to a pendant, or as a decor piece on your mantle or shelf.
Metaphysically, it is a powerful protective stone. It helps shield you from negativity and disharmony and cuts ties with negative people. This stone is also said to help clear psychic blockages and may even stimulate your psychic abilities. Because of its often shiny surface, it has been used as a scrying mirror by some people.
*Moons are cross listed.
