Each gem, mineral, crystal, and stone discussed in this volume has its own unique properties. Look at it this way: We have a vast healing and life-enhancing trove of beautiful and sacred stones from which to choose, and each stone has its own inherent, divine qualities. Each one is unique for the energy it emits and how it interacts with our subtle energy field, or aura. In the same way that no two fingerprints or snowflakes are alike, each crystal is completely individual, never to be repeated again in nature. Man-made crystals are exactly alike, thus reducing their appeal and healing qualities, at least in my mind.
Crystals found in nature are imbued with special qualities from the minerals and rocks surrounding them. Geologists are fond of explaining the varying colors of crystals as chemical impurities, and while that may well be so, I prefer to liken the development of crystalline color to the making of a fine wine, wherein the soil and even the neighboring trees, plants, sun, and rain affect the grapes and the resulting nectar. So, gems have notes, like a perfume or a wine or even music. Truly gifted gemologists can distinguish these delicate differences, especially the vibratory sounds.
