Obsidian works extremely fast and with great power. 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. Towers are wonderful to use as a centerpiece for your crystal grid or altar. It helps enhance reflection to expose blockages and relieve tension. Obsidian is a strongly protective stone and strengthens you in times of need.
