These crystals are recognised by a having a wedge shaped appearance, rather like a chisel. They do not terminate in a point, but in a horizontal line. These crystals may be used for scanning the body prior to bodywork, or for scanning anything you wish to have more information about. With the crystal in your receiving hand, pass it a few inches above what is being scanned, leaving the mind open to receive visual or other impressions. It may also be used as a tool help to smooth out energy knots or dissolve blockages in the auric field, using it in gentle sweeps through the energy field.
