Rainbow Fluorite is a particularly colourful variety of Fluorite displaying bands or zones in shades that may include purple, green, blue, yellow, and clear. Traditionally associated with clarity, balance, focus, creativity, and personal growth, Rainbow Fluorite is often appreciated as a stone representing harmony between different aspects of life. Because of its range of colours, it is traditionally associated with multiple chakras, depending on the individual colouring of each piece. Its naturally vivid bands make every specimen unique and add a playful, magical quality to any crystal collection.
