A thumb stone (also known as a worry stone) are smooth, polished gemstones, usually in the shape of an oval with athumb-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.
