These "pocket tranquilizers" use a form of reflexology, or nerve pressure. Rubbing the smooth surface of the stone puts pressure on nerves within your thumb that release endorphins, your brain's natural relaxants. You also benefit from the properties of the stone itself.
Information about using worry stones and the properties of Clear Quartz is included with purchase, as well as information about how to use stones.
I purchased two of these lovely quartz crystals. One for hubby and one for myself. They feel 'good' to hold and add comfort to a troubled spirit. The power of clear quartz can never be understated. It is always a joy for me to browse and purchase product from this lovely shop.
Thank you my friend :) Diane
