Here’s what to know about the benefits of rainbow fluorite and how to tap into them, according to experts. Varieties of fluorite, including rainbow, can be found all over the world, from Russia to China to South Africa, as well as in parts of the United States. According to Yulia Van Doren, author of Crystals: The Modern Guide to Crystal Healing and founder of Goldirocks, people have been working with the colorful stone for centuries. (It’s even thought to have been given the nickname “Genius Stone” by medieval alchemists.) Fluorite is thought to be a particularly good crystal for assisting with focus, clear thinking, and creative inspiration. “Its swirling bands of greens, purples, and blues have a calming effect on both mind and body,” Van Doren adds. She considers it a great earth ally to keep on hand when you’re working, studying, or just hoping to have a chill but productive day. Askinosie adds that this crystal can also be used to hold intentions like inner harmony, peace, and serenity. Hold the stone in your hand as you prepare for the task. As you do, visualize yourself getting through it with confidence and ease, and direct some of that positive energy into your rainbow fluorite. Then, take the stone into the presentation or conversation as a pre-charged good luck charm. Hold it in your hand or put it over your chest as you do some deep breathing to unwind before bed, she recommends. “Put it somewhere it will be able to soak in sunlight and moonlight for a full 24-hour cycle,” she says, noting that an indoor windowsill would be a good place to store it when it’s not in use. After a long time in direct sun, be aware that this stone will start to slowly fade. “If you wish to keep one on your windowsill, I would say go for it, because this crystal’s bands of colors are really shown off best in sunlight,” Van Doren says. “Just know that after a year or two, its colors will be a bit lighter.” Askinosie agrees that sunlight can help keep your stone clean. She adds that you can also put some fresh water on a soft cloth and use that to wipe off your crystal from time to time. Keep in mind, however, that fluorite and its different varieties are porous, so they should not be left to sit in water.
