Fluorite

The information found for each crystal is a generalization. Each crystal has it’s own vibration, or “personality”, and will work with you in the way that’s most needed at the time – the more you work with your crystal, the more it will intuitively communicate and work with you. Please remember to cleanse your crystals regularly to prevent breakage, in the way that is most beneficial for your crystal.
"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. Fluorite absorbs negative energies from the environment and is effective at Auric and Chakra cleansing. Fluorite can also shield the user from psychic manipulation. Fluorite should be cleared often.
