Unique Gemstone of Saphire
In earlier times, some people believed that the firmament was an enormous blue sapphire in which the Earth was embedded. Could there be a more apt image to describe the beauty of an immaculate sapphire? And yet this gem comes not in one but in all the blue shades of that firmament, from the deep blue of the evening sky to the shining mid-blue of a lovely summer's day which casts its spell over us. However, this magnificent gemstone also comes in many other colours: not only in the transparent greyish-blue of a distant horizon but also in the gloriously colourful play of light in a sunset – in yellow, pink, orange and purple. Sapphires really are gems of the sky, although they are found in the hard ground of our 'blue planet'.
Blue is the main colour of the sapphire. Blue is also the Sophirefavourite colour of some 50 per cent of all people, men and women alike. We associate this colour, strongly linked to the sapphire as it is, with feelings of sympathy and harmony, friendship and loyalty: feelings which belong to qualities that prove their worth in the long term – feelings in which it is not so much effervescent passion that is to the fore, but rather composure, mutual understanding and indestructible trust. Thus the blue of the sapphire has become a colour which fits in with everything that is constant and reliable. That is one of the reasons why women in many countries wish for a sapphire ring on their engagement. The sapphire symbolises loyalty, but at the same time it gives expression to people's love and longing. Perhaps the most famous example of this blue is to be found in music, in George Gershwin's "Rhapsody in Blue". And the blue of the sapphire even appears where nothing at all counts except clear-sightedness and concentrated mental effort. The first computer which succeeded in defeating a world chess champion bore the remarkable name 'Deep Blue'.
What makes the sapphire so fancy? Image : wikipedia.org Sapphires, call them gemstones of the sky though we may, lie well hidden in just a few places, and first have to be brought to light Sophirethrough hard work. Sapphires are found in India, Burma, Ceylon, Thailand, Vietnam, Australia, Brazil and Africa. From the gemstone mines, the raw crystals are first taken to the cutting-centres where they are turned into sparkling gemstones by skilled hands. When cutting a sapphire, indeed, the cutter has to muster all his skill, for these gemstones are not only hard. Depending on the angle from which you look at them they also have different colours and intensities of colour. So it is the job of the cutter to orientate the raw crystals in such a way that the colour is brought out to its best advantage. Depending on where they were found, the colour intensity and hue of the cut stones vary, which means, later on, that the wearer is rather spoilt for choice. Should she perhaps go for a mid-blue stone which will remind her even on rainy days of that shining summer sky? Or should she prefer a lighter blue because it will continue to sparkle vivaciously when evening falls? The bright light of day makes most sapphires shine more vividly than the more subdued artificial light of evening. So in fact it is not, as is often claimed, the darkest tone that is the most coveted colour of the blue sapphire, but an intense, rich, full blue which still looks blue in poor artificial light.
Specialists and connoisseurs regard the Kashmir colour with its velvety shine as the most beautiful and most valuable blue. These magnificent gemstones from Kashmir, found in 1880 after a landslide at an altitude of 16,000 feet and mined intensively over a period of eight years, were to have a lasting influence on people's idea of the colour of a first-class sapphire. Typical of the Kashmir colour is a pure, intense blue with a very subtle violet undertone, which is intensified yet more by a fine, silky shine. It is said that this hue does not change in artificial light. But the Burmese colour is also regarded as particularly valuable. It ranges from a rich, full royal blue to a deep cornflower blue.
The oldest sapphire finds are in Ceylon, or Sri Lanka as it is known today. Meanwhile, experts in Tanzania have also found initial evidence of two large-scale gemstone deposits in the form of some good, if not very large sapphire crystals coloured blue, green, yellow and orange. And the third country to register new finds recently was Brazil, where sapphires ranging from blue to purple and pink have been discovered. So lovers of the sapphire need not worry: there will, in future, be enough of these 'heavenly' gems with the fine colour spectrum. Top-quality sapphires, however, remain extremely rare in all the gemstone mines of the world.
