Sapphire, the celestial gemstone, has been treasured for thousands of years. In ancient Greece and Rome, kings and queens believed that blue sapphires possessed the power to make peace between enemies and attract heavenly blessings. Ancient healers used the blue sapphire to lead them to prophecy and command the spirits. Commoners used sapphire in antidotes for poison and poisonous bites, to clear the mind and the skin, and cure fevers and colds. Sapphires were also used to fight the plague. Sapphire has long symbolized truth, sincerity, and faithfulness.
The most important influence on a blue sapphire’s value is its colour, which can appear in a variety of hues, tones, and degrees of saturation. The saturation should be as strong as possible without darkening the tone too much. The most valuable blue sapphire colours are velvety, violetish blue to blue with medium to mediumdark tone and strong to vivid saturation. Sapphires can be found in colours ranging from firey reddish-orange sunset, to the delicate violet of twilight.
DURABILITY, TREATMENT AND CARE
Sapphires can scratch almost anything, and no natural gemstone other than diamond can scratch them. In fact, non-gem-quality corundum, is often used to cut and polish other coloured stones. Treatment of sapphires is not only common practice but is thought of as an art form in itself. Sapphire is commonly heat treated to improve colour and sometimes clarity. Warm, soapy water is safe for cleaning.
