Pocket Book of Stones: Who They Are and What They Teach by Robert Simmons

Robert Simmons’s revised pocket reference covers 390 crystals, gems and minerals in an A-to-Z format. Color photographs accompany mineral information, keywords and elemental and chakra correspondences.

Entries also explain the spiritual qualities Simmons associates with each stone and suggest combinations for personal practice. It suits newcomers and readers who want a compact reference; these metaphysical interpretations are not medical treatment advice.
