For restless hands and a busy mind. An amethyst thumb stone, about 35 × 45 mm.
Something for your thumb when your thoughts won't stop.
Thumb stones, also called worry stones, have a shallow dip for your thumb to rub back and forth, and people have kept smooth stones this way for a very long time. This one is amethyst, the crystal-tradition stone of calm, purple with white bands.
The story
One gem legend says Saint Valentine wore an amethyst ring engraved with Cupid. The story gives the purple stone a place in the lore of affection, alongside the quieter meanings crystal lovers often give it today.
Carrying it your way
Keep it on your desk or in a pocket. On a call that's going in circles, rub the groove slowly a few times; it gives your hands something to do besides checking your phone.
