Fluorite can come in a wide variety of colours, and is sometimes known as the most colourful crystal in the world. The different colours come from various impurities, exposure to radiation and a few other chemical composition variations.
Fluorite is a stone often used for protection, helps cleanse yourself of negativity and stress, and can help you focus your mind. It also is a great aid when you're working on balancing yourself.
Do not get your fluorite stones wet.
