Legendary healer Diane Stein shares her extensive knowledge of gemstones in this concise agate-to-zircon reference. Each listing includes the stone's common name, its corresponding color and chakra, and a concise resume of its healing properties. Stein suggests ways to use stones to support physical and psychic well-being, by simply carrying one in a hand or pocket, wearing it as jewelry, or engaging in more advanced practices like the "laying on of stones." She also presents a glossary of terms designed for beginning students of metaphysical healing practices, and teaches how to clear, dedicate, and maintain crystals to maximize their beneficial effects.
