Lithomancy.

The divination method using stones popular in the British Isles and Europe. Each stone supposedly has a significance of its own, and the divination is accomplished by tossing the stones and interpreting the arrangement in which they fall.

Thirteen stones are used. They are selected from their natural environment during favorable astrological configurations, and with the aid of intuitional guidance. Ideally, the stones should be smooth and nearly uniform in size and shape. They may range from pebbles found on a beach to semiprecious stones such as agates or various crystals.

Seven stones represent astrological signs: the sun, moon, Mars, Venus, Mercury, Jupiter and Saturn. The remaining six stones represent the home, love, life, magic, luck and news.

Divinatory stones may be kept in a "charm" bag
