Rutilated Quartz is an illuminator for the soul, promoting spiritual growth. It cleanses and energises the aura. Draws off negative energy and disease, letting go of the past. Rutilated Quartz gives protection against the ill thoughts of others. Great for jewelry, medicine or amulet bags, or carry with you. Picked at random, each stone is a minimum of 23mm or larger. I bought out a metaphysical store many years ago (hence the VERY low price!), 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.
