Fluorite is a highly protective and stabilizing stone, useful for grounding and harmonizing spiritual energy. When working with the upper Chakras, Fluorite increases intuitive abilities, links the human mind to universal consciousness, and develops connection to Spirit. Fluorite further anchors intuitive insights into the physical plane, allowing mental and physical coordination.
Fluorite heightens mental abilities, assisting in rapid organization and processing of information, and can bring mental clarity and stability to an otherwise chaotic situation.
