These are all natural gemstones and each one takes on a part of the body for spiritual and physical healing. This also clears and cleanses all areas, brain and body.
One does the arms, breasts, legs, various organs, etc. You just wear the piece when it is needed and can be used at any time. For each issue you should wear the piece for one day. To activate the piece you only need to warm it up in your hands because that is how it feels what to do. Once you do that you just wear it and it will fit anyone.
