The sky is just a gigantic blue Sapphire stone into which the earth is embedded – this belief was cherished in ancient times. And, in fact, does there exist a better image to describe the beauty of an immaculate Sapphire of purest blue? This gemstone exists in all the shades of blue skies, from the deep blue of evening skies to the bright and deep blue of a clear and beautiful summer sky which charms all people. The splendid gemstone, however, also comes in many other colors, not only in the transparent grayish misty blue of far horizons, but also displaying the bright fireworks of sunset colors – yellow, pink, orange and purple. So Sapphires are really and truly heavenly stones, although they are being found in the hard soil of our so-called "blue planet”. Blue is Sapphire’s main color. Blue is also the favorite color of about 50 per cent of the population, men and women alike. This color, which is strongly associated with sapphire, is also linked to emotions such as sympathy and harmony, friendship and loyalty. These emotions belong to features which are permanent and reliable – emotions where overwhelming and fiery passion is not the main element, but rather composure, mutual understanding and unshakeable trust. Sapphire blue has thus become a color related to anything permanent and reliable, and this is one of the reasons why women in many countries settle on Sapphire for their engagement rings. Sapphire symbolizes loyalty and faithfulness, while at the same time expressing love and yearning. The throne of celestial judgment is supposed to rest on sapphire. According to the Book of Revelation, it is the second stone in the foundation of the New Jerusalem. One ancient writer noted that "the figure of a ram or bearded man engraved on a sapphire has the power to cure a person from many ailments and free him from poison or demons." At the time it was believed to remove all impurities and foreign matter from the eyes. It is said that Charles IV used an oval sapphire for this purpose. Since the sapphire was supposed to produce such beneficent magic, evil could not prevail in its presence. The very proximity of the stone would kill reptiles as well as venomous insects. The sapphire was long honored as a talisman against evil spirits. When King Solomon adopted the sapphire for his seal, the stone became even more of a symbol of wisdom and clear thinking. This latter quality is the one it still represents today as the birthstone of September.
