Fluorite is a calcium fluoride mineral that commonly forms in cubic crystals, often with vibrant color zoning. The El Filo vein fluorites are particularly known for their beautiful purple hues, and often display stepped growth structures. Fluorite is relatively soft, with a hardness of 4 on the Mohs scale, and is often found in association with quartz and calcite​.
 
Fluorite is associated with its ability to clear negative energy and provide mental clarity. It's often used to aid in enhancing decision-making, focus, and balancing the mind. Purple fluorite, like that from the El Filo vein, is especially linked to spiritual growth, enhancing connection to higher realms of consciousness, and supporting intuition and psychic abilities. It’s also associated with the third eye chakra, helping to sharpen intuition and spiritual insight.
