It is said that danburite is a very high vibrational stone that activates and aligns one's heart and crown chakras together. This unique channel allows one the ability to process any emotions with a clear and conscious mind, while also raising one's decision making ability. It is also a believed to be a natural magnifier and intensifier, as well as an intellectual activator, bringing both stimulus and responsiveness to the user. Great for jewelry, medicine or amulet bags, or carry with you. Picked at random, each stone is a minimum of 15mm or larger. I bought out a metaphysical store many years ago, and these were part of the many treasures included. I was not given a location where they were found, and I cannot obtain more. Sold individually, undrilled. NOTE: If you are buying more than one item or lot, I will figure out actual shipping based on weight and refund you any difference.
