Worry Stones are a perfect solution for those looking to burn off nervous energy and ground themselves in times of stress and anxiety or just when you need something to fidget with. Each stone is beautifully polished and comes in a variety of different crystals, including black onyx, rose quartz, amethyst, fancy agate, and clear quartz. When you order, you'll receive a random stone, selected just for you. Keep it in your pocket or purse for an instant source of comfort and calm whenever you need it.  Simply rub your thumb over the smooth surface while taking deep breaths to feel the grounding effects.
