Earth Mined Natural Diamonds
Diamonds have always fascinated men and women from all ages and all walks of life, because of its hardness, brilliance, history, glamour overtones and legends. Diamonds became the symbol of our ideals we value most. For centuries diamonds have appeared in royal treasuries and adventurers have journeyed thousands of miles to search for them. Diamonds are more than jewels; they are a part of our pre-history.
Formation of diamonds
At depth below approximately 120 and 200 kilometers below the earth's surface where extreme temperatures exist, carbon atoms are attracted together in an orderly pattern. This area is called The Diamond Stability field. During the earth's history natural diamonds were delivered to the surface by a special kind of volcanic eruption. The most recent of these eruptions was about 45 million years ago.
Fluorescence in a diamond
Fluorescence is the effect that is seen in some gem-quality diamonds when they are exposed to long-wave ultraviolet light (such as the lighting frequently seen in dance clubs). Under most lighting conditions, this fluorescence is not detectable by eye. However, if a diamond is naturally fluorescent, it will emit a soft colour glow when held under an ultraviolet lamp or "black light". Fluorescence is not dangerous to the diamond or to the wearer; it is a unique and fascinating quality that occurs naturally in a number of gems and minerals and some diamonds do not fluoresce at all.
