The so called Luna, half moon, or sickle of the moon, also waning and waxing moon, is a sign of fertility, related to life and death, and thus a popular symbol in many religions. It pinpoints changing seasons, ebb and tide (and related inundations as harbingers of fertility), and the feminine menstrual cycle. Kyanite is one of the two minerals on the planet that neither accumulates nor retains negative energy, and therefore never needs cleansing. These symbolic rings are selling well in Metaphysical, Spiritual, and Lifestyle stores in North America and Europe. Kyanite's energy is unlimited in application, making it an excellent stone for metaphysical purposes, and it may be used for cleansing and clearing other crystals.. . .
