The Encyclopedia of Crystals
Organized by crystal color, HallÆs (The Crystal Bible) comprehensive guide provides valuable information on nearly 1000 existing and newly discovered stones, their fluorescent properties, and their mineral content. In the instructive foreword, she describes the eight fundamental crystal structures, historical uses, and elemental formation. She also gives directions for activating crystalsÆ cleansing and healing properties and discusses their relationship to chakras. Five hundred gorgeous, sensuously colored photographs accompany the entries. Because the book addresses subjects relevant to both scientific interest and alternative therapy, it is highly recommended for collections focusing on geology or holistic therapies.-Library Journal  April 2007
