Very nice Quartz or Black Obsidian Crystal pendant that has corresponding chakra gems. Both balance the chakras.
Black Obsidian is a grounding stone that provides an instant connection from the Root Chakra deep into the core of the Earth. Black Obsidian will help to clean and remove negative energies in a sacred space or environment. It also assists in releasing those emotions/reactions that cause negative energy such as anger, jealousy, greed, resentment, etc. Once these energies are removed/released, Black Obsidian will help to keep the space protected.
