Pietersite is said to enhance vision and astral travel, dispell illusions and promote loyalty to self. Because its swirling colors resemble a storm, pietersite is known as tempest stone. Pietersite is said to center on the spiritual being with the ability to ground an individual to the etheric body--the first or lowest layer in the "human energy field" or aura. Pietersite discharges negative energies and emotional turmoil while cleansing the aura, restoring it to calm. Pietersite is thought to work with the body during meditation, rapidly moving into a higher state of awareness. Pietersite is believed to be a stone of vision and can be used for a vision quest or shaman journey. According to metaphysical beliefs, pietersite promotes a concerted activation of the sacral and solar plexus chakras, as well as the third eye, creating a powerful increase in the energy of will and in one's intuitive capabilities. Pietersite is an extremely supportive and strengthening stone that increases self-esteem. Great for jewelry, medicine or amulet bags, or carry with you. Picked at random, each stone is a minimum of 18mm. 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 per 2, 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.
