Begin with four, not forty
Choose one stone for calm, one for focus, one for warmth and one that simply catches your eye. A small collection is easier to learn, care for and actually use.
Notice the material first
Color, hardness, polish and natural inclusions tell you more than a long list of promises. Keep a simple note of where the stone came from and how it should be cleaned.
Build a two-minute ritual
Place one stone near your notebook, take a slow breath and name the quality you want to bring to the next task. The object is a cue for attention, not a medical treatment.
