The polished palmstone is the perfect form for laying on the body or to hold in the hands to extract & transmute toxic energy held in the body or energy field. An excellent use is to have a large Indigo Gabbro Palmstone under each of your bare feet while working at a desk, or relaxing, watching TV etc. Do wash the stone after each use, even though this is the most self-clearing of all stones we have tested. Can also be placed on EMF sources or their power cords, or on Geopathic Earth Lines, for transmuting and protection. Note that the Large and Extra Large Palmstones are hard to find and in Limited Supply.
