Garnets


Aren't garnets those wonderful deep-red gemstones you often find in antique jewellery? Well yes, to a certain extent, a deep, warm red indeed being the colour most frequently found in garnets. Sadly, however, far too few people are aware that the world of the garnets is far more colourful than that. Spectacular finds, especially in Africa, have enhanced the traditional image of the garnet with a surprising number of hues - even if red does continue to be its principal colour. Thanks to their rich colour spectrum, garnets today can quite happily keep pace with changes of style and the colour trends of fashion. And thanks to the new finds, there is a reliable supply of them too. So in fact this gemstone group in particular is one which gives new impetus to the world of jewellery today.By the term 'garnet', the specialist understands a group of more than ten different gemstones of similar chemical composition. It is true to say that red is the colour most often encountered, but the garnet also exists in various shades of green, a tender to intense yellow, a fiery orange and some fine earth-coloured nuances. The only colour it cannot offer is blue. Garnets are much sought-after and much worked gemstones - the more so because today it is not only the classical gemstone colours red and green which are so highly esteemed, but also the fine hues in between. Furthermore, the world of the garnets is also rich in rarities such as star garnets and stones whose colour changes depending on whether they are seen in daylight or artificial light.And what else is there that distinguishes this gemstone group from the others? Well, first of all there is its good hardness of 7 to 7.5 on the Mohs scale. With a few minor exceptions it applies to all the members of the garnet group, and it is the reason for the excellent wearing qualities of these gemstones. Garnets are relatively insensitive and uncomplicated to work with. The only thing they really don't like is being knocked about or subjected to improper heat treatment. A further plus is their high refractive index, the cause of the garnet's great brilliance. The shape of the raw crystals is also interesting. Garnet means something like 'the grainy one', coming from the Latin 'granum', for grain. This makes reference not only to the typical roundish shape of the crystals, but also to the colour of the red garnet, which often puts one in mind of the seeds of a ripe pomegranate. In the Middle Ages, the red garnet was also called the 'carbuncle stone'. And even today, fantasy names like Arizona ruby, Arizona spinel, Montana ruby or New Mexico ruby are still rife in the trade.

Sapphire


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 favourite 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'.

Ruby


Which colour would you spontaneously associate with love and vivacity, passion and power? It's obvious, isn't it? Red. Red is the colour of love. It radiates warmth and a strong sense of vitality. And red is also the colour of the ruby, the king of the gemstones. In the fascinating world of gemstones, the ruby is the undisputed ruler.For thousands of years, the ruby has been considered one of the most valuable gemstones on Earth. It has everything a precious stone should have: magnificent colour, excellent hardness and outstanding brilliance. In addition to that, it is an extremely rare gemstone, especially in its finer qualities.For a long time India was regarded as the ruby's classical country of origin. In the major works of Indian literature, a rich store of knowledge about gemstones has been handed down over a period of more than two thousand years. The term 'corundum', which we use today, is derived from the Sanskrit word 'kuruvinda'. The Sanskrit word for ruby is 'ratnaraj', which means something like 'king of the gemstones'. And it was a royal welcome indeed which used to be prepared for it. Whenever a particularly beautiful ruby crystal was found, the ruler sent high dignitaries out to meet the precious gemstone and welcome it in appropriate style. Today, rubies still decorate the insignia of many royal households. But are they really all genuine rubies? Read on to find out more!

The mining operation for gems has been virtually the same since the days of the Alexander the Great or perhaps the Pharaohs times except for the modern addition of the water pumps for dewatering of the pits. The supports for the excavations are still mostly the logs. Labour is provided as a share to the earnings as well as the equipment, materials as well as the daily expenses such as food too are contributed as a share.

GEM Mining

Mining for ruby and sapphire began in Macon County in 1870. Called corundum, the minerals were mined commercially for abrasives and gave work to many men. Corundum and other minerals, mica and kaolin, were hauled to the railroad by horse and wagon and shipped out of Macon County in large quantities. Tiffany's showed an interest in the area in the 1890's but two other companies, American Prospecting & Mining Co. and US Ruby Mining Co., began work hoping to find the source of the rubies found in the corundum mines. Both companies ended the search in the early part of the 20th century leaving the area open to rockhounds and gem enthusiasts. The source hasn't been found - yet.
