GEMSTONE CHARTS |
| |
Since the primeval age of history precious stones have always been associated with man. Primitive people appreciated their value as jewelry, and knew perfectly well how to make full use of their special qualities. Precious stones were belived to possess some mysterious, magical properties, and a special healing power. Stones were thought to be connected with the stars and were believed to be able to influence human fate. Therefore everybody should carry his so-called "birth-stone" with him (the stone for the month in which he was born), as this was supposed to safeguard his health, happiness and property. At first precious stones were used in their natural form. Only later people began to polish them to stress their color and lustre. The art of treating precious stones was best understood by the Indians and Egyptians. The optical properties of transparent stones was enhanced by a symmetrical cut of small, smooth surfaces called facets. |
