A worry stone, or calming stone, is a little trinket used to ground yourself. You can meditate with it, play with it like a fidget or stim toy. It can be a calming presence, especially in times of anxiety, depression, overstimulation or stress.

Worry stones have been used throughout history in different parts of the world. The Ancient Greeks pulled them from the sea and used them for calming themselves. Indigenous peoples held them and passed them on from generation to generation.
