Description All of our Minerals & Crystals are 100% Genuine Specimens & come with a Certificate of Authenticity! Worry stones are smooth, polished gemstones, usually in the shape of an oval with a thumb-sized indentation, used for relaxation or anxiety relief. The smoothness of the stone is most often created naturally by running water. The size of a worry stone is often about half the size of a silver dollar coin in the United States. 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. This action of moving one’s thumb back and forth across the stone can reduce stress. Worry stones may also be called palm stones, thumb stones, fidget stones, soothing stones, or sensory stones. Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate. Calcite is a common constituent of sedimentary rocks, limestone in particular, much of which is formed from the shells of dead marine organisms. Approximately 10% of sedimentary rock is limestone.
