Thumb 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 the thumb back and forth across the stone. This action of moving the thumb back and forth across the stone can reduce stress, and aid relaxation and meditation.
The smoothness of the stone is most often created naturally by running water.
