Lithomancy

Lithomancy is divination by stones. In its most common modern form, a small set of stones or crystals, each associated with a theme (love, work, luck, communication), is cast and read according to where the stones land and how close they fall to one another. It can also involve gazing at the reflections in a polished stone or drawing a stone at random. It is distinct from crystal healing, which credits stones with healing properties, a claim no study has borne out.
