Clear Quartz Crystal is a power stone that harmonizes and balances. It augments energy by absorbing, amplifying, and balancing, storing, retrieving, focusing, transmitting and channelling universal energy and is excellent for unblocking it. A powerfully protective stone, it also purifies on all levels; spiritual, emotional, mental, and physical. Because it directs and amplifies energy it is exceptionally beneficial for manifesting, meditation, and channelling. (Source: lillypadvillage.com)
 
Worry stones are smooth, polished gemstones, usually in the shape of an oval with a thumb-sized indentation, used for relaxation or anxiety relief. They are used by holding the stone between the index finger and thumb and gently moving one's thumb back and forth across the stone.
