Selenite is most closely associated with the crown chakra, which represents wisdom and spirituality, as well as the third eye chakra. They are believed to be a stone of protection that wards the mind.
Selenite is a high-energy crystal that vibrates at a high frequency which is why it is an energy purifier and I recommend having one in each room. Selenite has the power to cleanse & charge other crystals as well which is why I have a Smoky Quartz beside my Selenite. One attracts all the energy that isn't welcome and the Selenite disposes of it by clearing the Quartz. Simply lay your crystals on or near your Selenite for a few hours at a time.
Selenite is not a birthstone, but is associated with Cancer.
