We use earth gifts for healing when doing Reiki or sending distant healing. These 3 are on a healing alter. There are so many more and books on the subject can assist you in learning more if you are interested.
This pic shows two rocks both of which fluoresce bright green due to uranyl (UO2). The upper rock (3" wide) is meta-autunite from the Daybreak Mine in Spokane, Washington and the lower rock is a geode containing chalcedony that I got this summer as a doorprize at a meeting of the Fluorescent Mineral Society. Shown in SW light. Meta-autunite obtained from Minershop.com. Chalcedony obtained from FMS.
