LEARN ABOUT SOME PRECIOUS STONES
Which color would you spontaneously associate with love and vivacity, passion and power? It’s obvious, isn’t it? Red. Red is the color of love. It radiates warmth and a strong sense of vitality. And red is also the color 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 color, 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!
Ruby is the red variety of the mineral corundum, one of the hardest minerals on Earth, of which the sapphire is also a variety. Pure corundum is colorless. Slight traces of elements such as chrome, iron, titanium or vanadium are responsible for the color. These gemstones have excellent hardness. On the Mohs scale their score of 9 is second only to that of the diamond. Only red corundum is entitled to be called ruby, all other colors being classified as sapphires. The close relationship between the ruby and the sapphire has only been known since the beginning of the 19th century. Up to that time, red garnets or spinels were also thought to be rubies. (That, indeed, is why the ‘Black Ruby’ and the ‘Timur Ruby’, two of the British Crown Jewels, were so named, when they are not actually rubies at all, but spinels.)
Ruby, this magnificent red variety from the multi-colored corundum family, consists of aluminum oxide and chrome as well as very fine traces of other elements – depending on which deposit it was from. In really fine colors and good clarity, however, this gemstone occurs only very rarely in the world’s mines. Somewhat paradoxically, it is actually the coloring element chrome which is responsible for this scarcity. True enough, millions of years ago, when the gemstones were being created deep inside the core of the Earth, chrome was the element which gave the ruby its wonderful color. But at the same time it was also responsible for causing a multitude of fissures and cracks inside the crystals. Thus only very few ruby crystals were given the good conditions in which they could grow undisturbed to considerable sizes and crystallize to form perfect gemstones. For this reason, rubies of more than 3 carats in size are very rare. So it is no wonder that rubies with hardly any inclusions are so valuable that in good colors and larger sizes they achieve top prices at auctions, surpassing even those paid for diamonds in the same category.
Some rubies display a wonderful silky shine, the so-called ‘silk’ of the ruby. This phenomenon is caused by very fine needles of rutile. And now and then one of the rare star rubies is found. Here too, the mineral rutile is involved: having formed a star-shaped deposit within the ruby, it causes a captivating light effect known by the experts as asterism. If rubies of this kind are cut as half-dome shaped cabochons, the result is a six-spoked star which seems to glide magically across the surface of the stone when the latter is moved. Star rubies are precious rarities. Their value depends on the beauty and attractiveness of the color and, though only to a lesser extent, on their transparency. Fine star rubies, however, should always display rays which are fully formed all the way to the imaginary horizontal line which runs through the middle of the stone, and the star itself should be situated right in the center.
Red for ruby. Ruby-red. The most important thing about this precious stone is its color. It was not for no reason that the name ‘ruby’ was derived from the Latin word ‘rubens’, meaning ‘red’. The red of the ruby is incomparable: warm and fiery. Two magical elements are associated with the symbolism of this color: fire and blood, implying warmth and life for mankind. So ruby-red is not just any old color, no, it is absolutely undiluted, hot, passionate, powerful color. Like no other gemstone, the ruby is the perfect way to express powerful feelings. Instead of symbolizing a calm, controlled affection, a ring set with a precious ruby bears witness to that passionate, unbridled love that people can feel for each other.
Which is the most beautiful ruby-red? Good question. The red of a ruby may involve very different nuances depending on its origin. The range of those nuances is quite wide, and could perhaps be compared to hotel categories, from luxury accommodation down to a plain inn or hostel. For example, if the gemstone experts refer to a ‘Burmese ruby’, they are talking about the top luxury category. However, it does not necessarily follow that the stone is of Burmese origin. It is basically an indication of the fact that the color of the ruby in question is that typically shown by stones from the famous deposits in Burma (now Myanmar): a rich, full red with a slightly bluish hue. The color is sometimes referred to as ‘pigeon-blood-red’, but the term ‘Burmese color’ is a more fitting description. A connoisseur will immediately associate this color with the legendary ‘Mogok Stone Tract’ and the gemstone centre of Mogok in the North of Myanmar. Here, the country’s famous ruby deposits lie in a mountain valley surrounded by high peaks. Painstakingly, gemstones of an irresistible luminosity are brought to light in the ‘valley of the rubies’. Unfortunately, really fine qualities are quite rare even here. The color of a Burmese ruby is regarded as exceptionally vivid. It is said to display its unique brilliance in any light, be it natural or artificial.
The journey to the world’s most important ruby deposits takes us further on to the small town of Mong Hsu in the North-East of Myanmar, where the most important ruby deposits of the nineties lie. Originally, it was believed that these rubies would hardly prove suitable for use in jewelry, since untreated Mong Hsu ruby crystals actually display two colors: a purple to black core and a bright red periphery. Only when it had been discovered that the dark core could be turned into deep red by means of heat treatment did rubies from Mong Hsu begin to find their way on to the jewelry market. Today, the Mong Hsu gemstone mines are still among the most important ruby suppliers. In the main, they offer heat-treated rubies in commercial qualities and sizes between 0.5 and 3 carats.
Ruby deposits also exist in neighboring Vietnam, near the Chinese border. Rubies of Vietnamese origin generally display a slightly purplish hue. Rubies from Thailand, another classical supplier, however, often have a darker red which tends towards brown. This ‘Siamese color’ – an elegantly muted deep red – is considered second in beauty only to the Burmese color, and is especially popular in the USA. Ceylon rubies, which have now become very rare, are mainly light red, like ripe raspberries.
Other ruby deposits are located in Northern Pakistan in the Hunza Valley, Kashmir, Tadzhikistan, Laos, Nepal, and Afghanistan. But rubies are also produced in India, where deposits with relatively large crystals were discovered in the federal states of Mysore and Orissa. These crystals have many inclusions, but they are, nevertheless, eminently suited to being cut as beads or cabochons.
Lately, people have begun to talk about East Africa as a source of rubies. Straight after their discovery in the 1960s, rubies from Kenya and Tanzania surprised the experts by their beautiful, strong color, which may vary from light to dark red. But in the African mines too, fine and clear rubies of good color, purity and size are very rare. Usually the qualities mined are of a merely average quality.
As we have said, color is a ruby’s most important feature. Its transparency is only of secondary importance. So inclusions do not impair the quality of a ruby unless they decrease the transparency of the stone or are located right in the centre of its table. On the contrary: inclusions within a ruby could be said to be its ‘fingerprint’, a statement of its individuality and, at the same time, proof of its genuineness and natural origin. The cut is essential: only a perfect cut will underline the beauty of this valuable and precious stone in a way befitting the ‘king of the gemstones’. However, a really perfect ruby is as rare as perfect love. If you do come across it, it will cost a small fortune. But when you have found ‘your’ ruby, don’t hesitate: hang on to it!
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 colors: not only in the transparent grayish-blue of a distant horizon but also in the gloriously colorful 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 color of the sapphire. Blue is also the Sophirefavourite color of some 50 per cent of all people, men and women alike. We associate this color, 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’.
SophireIts beauty, its magnificent colours, its transparency, but also its constancy and durability are qualities associated with this gemstone by gemstone lovers and specialists alike. (This does not only apply to the blue sapphire, but more of that later on). The sapphire belongs to the corundum group, the members of which are characterised by their excellent hardness (9 on the Mohs scale). Indeed their hardness is exceeded only by that of the diamond – and the diamond is the hardest mineral on Earth! Thanks to that hardness, sapphires are easy to look after, requiring no more than the usual care on the part of the wearer.
The gemstones in the corundum group consist of pure aluminum oxide which crystallized into wonderful gemstones a long time ago as a result of pressure and heat at a great depth. The presence of small amounts of other elements, especially iron and chrome, are responsible for the coloring, turning a crystal that was basically white into a blue, red, yellow, pink or greenish sapphire. However, this does not mean that every corundum is also a sapphire. For centuries there were differences of opinion among the specialists as to which stones deserved to be called sapphires. Finally, it was agreed that the ruby-red ones, colored by chrome, should be called ‘rubies’ and all those which were not ruby-red ‘sapphires’.
If there is talk of the sapphire, most gemstone aficionados think immediately of a velvety blue. It’s a versatile color that becomes many wearers. A blue sapphire fits in best with a well balanced lifestyle in which reliability and temperament run together and there is always a readiness to encounter things new – as with the woman who wears it. The fact that this magnificent gemstone also comes in a large number of other colors was known for a long time almost only to insiders. In the trade, sapphires which are not blue are referred to as ‘fancies’. In order to make it easier to differentiate between them, they are referred to not only by their gemstone name but also by a description of their color. In other words, fancy sapphires are described as yellow, purple, pink, green or white sapphires. Fancy sapphires are pure individualism and are just made for lovers of individualistic colored stone jewelry. They are currently available in a positively enchanting variety of designs – as ring stones, necklace pendants or ear jewelry, as solitaires, strung elegantly together or as sparkling pavée.
However, the sapphire has yet more surprises in store. For example there is an orange variety with a fine pink undertone which bears the poetic name ‘padparadscha’, which means something like ‘lotus flower’. The star sapphires are another rarity, half-dome-cut sapphires with a starlike light effect which seems to glide across the surface of the stone when it is moved. There are said to have been gemstone lovers who fell in love with these sapphire rarities for all time. And indeed the permanence of relationships is one of the features that are said to belong to this gemstone.
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 through 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-centers 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 colors and intensities of color. So it is the job of the cutter to orientate the raw crystals in such a way that the color is brought out to its best advantage.
Depending on where they were found, the color 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 color of the blue sapphire, but an intense, rich, full blue which still looks blue in poor artificial light.
Specialists and connoisseurs regard the Kashmir color 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 color of a first-class sapphire. Typical of the Kashmir color 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 color 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. There, people were already digging for gemstones in ancient times. The specialist recognizes Ceylon sapphires by the luminosity of their light to mid-blue colors. Having said that, most blue sapphires come either from Australia or from Thailand.
Their value depends on their size, color and transparency. With stones of very fine quality, these are, however, not the only main criteria, the origin of the gem also playing a major role. Neither is the color itself necessarily a function of the geographical origin of a sapphire, which explains the great differences in price between the various qualities. The most valuable are genuine Kashmir stones. Burmese sapphires are valued almost as highly, and then come the sapphires from Ceylon. The possibility of the gemstone’s having undergone some treatment or other is also a factor in determining the price, since gemstones which can be guaranteed untreated are becoming more and more sought-after in this age of gemstone cosmetics. And if the stone selected then also happens to be a genuine, certificated Kashmir or Burmese, the price will probably reflect the enthusiasm of the true gemstone lover.
It is not often that daring pioneers discover gemstones on a scale such as was the case on Madagascar a few years ago, when a gemstone deposit covering an area of several miles was found in the south-east of the island. Since then, not only have there been enough blue sapphires in the trade, but also some splendid pink and yellow sapphires of great beauty and transparency. 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 colored 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 color spectrum. Top-quality sapphires, however, remain extremely rare in all the gemstone mines of the world.
Emeralds are fascinating gemstones. They have the most beautiful, most intense and most radiant green that can possibly be imagined: emerald green. Inclusions are tolerated. In top quality, fine emeralds are even more valuable than diamonds.
The name emerald comes from the Greek ‘smaragdos’ via the Old French ‘esmeralde’, and really just means ‘green gemstone’. Innumerable fantastic stories have grown up around this magnificent gem. The Incas and Aztecs of South America, where the best emeralds are still found today, regarded the emerald as a holy gemstone. However, probably the oldest known finds were once made near the Red Sea in Egypt. Having said that, these gemstone mines, already exploited by Egyptian pharaohs between 3000 and 1500 B.C. and later referred to as ‘Cleopatra’s Mines’, had already been exhausted by the time they were rediscovered in the early 19th century.
Written many centuries ago, the Vedas, the holy scriptures of the Indians, say of the precious green gems and their healing properties: ‘Emeralds promise good luck …’; and ‘The emerald enhances the well-being …’. So it was no wonder that the treasure chests of Indian maharajas and maharanis contained wonderful emeralds. One of the world’s largest is the so-called ‘Mogul Emerald’. It dates from 1695, emerald weighs 217.80 carats, and is some 10cm tall. One side of it is inscribed with prayer texts, and engraved on the other there are magnificent floral ornaments. This legendary emerald was auctioned by Christie’s of London to an unidentified buyer for 2.2m US Dollars on September 28th 2001.
Emeralds have been held in high esteem since ancient times. For that reason, some of the most famous emeralds are to be seen in museums and collections. The New York Museum of Natural History, for example, has an exhibit in which a cup made of pure emerald which belonged to the Emperor Jehangir is shown next to the ‘Patricia’, one of the largest Colombian emerald crystals, which weighs 632 carats. The collection of the Bank of Bogota includes five valuable emerald crystals with weights of between 220 and 1796 carats, and splendid emeralds also form part of the Iranian National Treasury, adorning, for example, the diadem of the former Empress Farah. The Turkish sultans also loved emeralds. In Istanbul’s Topkapi Palace there are exhibits with items of jewelry, writing-implements and daggers, each lavishly adorned with emeralds and other gems.
The green of the emerald is the color of life and of the springtime, which comes round again and again. But it has also, for centuries, been the color of beauty and of constant love. In ancient Rome, green was the color of Venus, the goddess of beauty and love. And today, this color still occupies a special position in many cultures and religions. Green, for example, is the holy color of Islam. Many of the states of the Arab League have green in their flags as a symbol of the unity of their faith. Yet this color has a high status in the Catholic Church too, where green is regarded as the most natural and the most elemental of the liturgical colors.
The magnificent green of the emerald is a color which conveys harmony, love of Nature and elemental joie de vivre. The human eye can never see enough of this unique color. Pliny commented that green gladdened the eye without tiring it. Green is perceived as fresh and vivid, never as monotonous. And in view of the fact that this color always changes somewhat between the bright light of day and the artificial light of a lamp, emerald green retains its lively vigor in all its nuances.
The lively luminosity of its color makes the emerald a unique gemstone. However, really good quality is fairly rare, with inclusions often marring the evenness of the color signs of the turbulent genesis which has characterized this gemstone. Fine inclusions, however, do not by any means diminish the high regard in which it is held. On the contrary: even with inclusions, an emerald in a deep, lively green still has a much higher value than an almost flawless emerald whose color is paler. Affectionately, and rather poetically, the specialists call the numerous crystal inclusions, cracks or fissures which are typical of this gemstone ‘jardin’. They regard the tender little green plants in the emerald garden as features of the identity of a gem which has grown naturally.
So where do they come from and how is it that they exist at all? In order to answer these questions, we need to look far, far back into the time of the emerald’s origin. Emeralds from Zimbabwe are among the oldest gemstones anywhere in the world. They were already growing 2600 million years ago, whilst some specimens from Pakistan, for example, are a mere 9 million years young. From a chemical-mineralogical point of view, emeralds are beryllium-aluminum-silicates with a good hardness of 7.5 to 8, and belong, like the light blue aquamarine, the tender pink morganite, the golden heliodor and the pale green beryl, to the large gemstone family of the beryls. Pure beryl is colorless. The colors do not occur until traces of some other element are added. In the case of the emerald, it is mainly traces of chromium and vanadium which are responsible for the fascinating color. Normally, these elements are concentrated in quite different parts of the Earth’s crust to beryllium, so the emerald should, strictly speaking, perhaps not exist at all. But during intensive tectonic processes such as orogenesis, metamorphism, emergences and erosion of the land, these contrasting elements found each other and crystallized out to make one of our most beautiful gemstones. The tension involved in the geological conditions conducive to the above processes produced some minor flaws, and some major ones. A glance through the magnifying-glass or microscope into the interior of an emerald tells us something about the eventful genesis of this unique gem: here we see small or large fissures; here the sparkle of a mini-crystal or a small bubble; here shapes of all kinds. While the crystals were still growing, some of these manifestations had the chance to ‘heal’, and thus the jagged three-phase inclusions typical of Colombian emeralds were formed: cavities filled with fluid, which often also contain a small bubble of gas and some tiny crystals.
Logically enough, a genesis as turbulent as that of the emerald impedes the undisturbed formation of large, flawless crystals. For this reason, it is only seldom that a large emerald with good color and good transparency is found. That is why fine emeralds are so valuable. But for the very reason that the emerald has such a stormy past, it is surely entitled to show it – that is, as long as only a fine jardin is to be seen, and not a rank garden which spoils both color and transparency.
Colombia continues to be at the top of the list in terms of the countries in which fine emeralds are found. It has about 150 known deposits, though not all of these are currently being exploited. The best known names are Muzo and Chivor, where emeralds were mined by the Incas in pre-Columbian times. In economic terms, the most important mine is at Coscuez, where some 60 faces are being worked. According to estimates, approximately three quarters of Colombia’s emerald production now comes from the Coscuez Mine. Colombian emeralds differ from emeralds from other deposits in that they have an especially fine, shining emerald green unimpaired by any kind of bluish tint. The colour may vary slightly from find to find. This fascinatingly beautiful color is so highly esteemed in the international emerald trade that even obvious inclusions are regarded as acceptable. But Colombia has yet more to offer: now and then the Colombian emerald mines throw up rarities such as Trapiche emeralds with their six rays emanating from the center which resemble the spokes of a millwheel.
Even if many of the best emeralds are undisputedly of Colombian origin, the ‘birthplace’ of a stone is never an absolute guarantee of its immaculate quality. Fine emeralds are also found in other countries, such as Zambia, Brazil, Zimbabwe, Madagascar, Pakistan, India, Afghanistan and Russia. Zambia, Zimbabwe and Brazil in particular have a good reputation for fine emeralds in the international trade. Excellent emerald crystals in a beautiful, deep emerald green and with good transparency come from Zambia. Their color is mostly darker than that of Colombian emeralds and often has a fine, slightly bluish undertone. Emeralds which are mostly smaller, but very fine, in a vivacious, intense green come from Zimbabwe’s famous Sandawana Mine, and they often have a delicate yellowish-green nuance. And the famous emerald mines of Colombia currently face competition from right next door: Brazil’s gemstone mine Nova Era also produces emeralds in beautiful green tones, and if they are less attractive than those of their famous neighbor it is only by a small margin. Brazil also supplies rare emerald cat’s eyes and extremely rare emeralds with a six-spoked star. Thanks to the finds in Africa and Brazil, there are more emeralds on the market now than there used to be – to the delight of emerald enthusiasts – .
While its good hardness protects the emerald to a large extent from scratches, its brittleness and its many fissures can make cutting, setting and cleaning rather difficult. Even for a skilled gem cutter, cutting emeralds presents a special challenge, firstly because of the high value of the raw crystals, and secondly because of the frequent inclusions. However, this does not detract from the cutters’ love of this unique gem. Indeed, they have developed a special cut just for this gem: the emerald cut. The clear design of this rectangular or square cut with its beveled corners brings out the beauty of this valuable gemstone to the full, at the same time protecting it from mechanical strain.
Emeralds are also cut in many other, mainly classical shapes, but if the raw material contains a large number of inclusions, it may often be cut into a gently rounded cabochon, or into one of the emerald beads which are so popular in India.
Today, many emeralds are enhanced with colorless oils or resins. This is a general trade practice, but it does have the consequence that these green treasures react very sensitively to inappropriate treatment. For example, they cannot be cleaned in an ultrasonic bath. The substances that may have been used by the cutter during his work, or applied subsequently, seal the fine pores in the surface of the gem. Removing them will end up giving the stone a matt appearance. For this reason, emerald rings should always be taken off before the wearer puts his or her hands in water containing cleansing agent.
Unfortunately, because the emerald is not only one of the most beautiful gemstones, but also one of the most valuable, there are innumerable synthetics and imitations. So how can you protect yourself from these ‘fakes’? Well, the best way is to buy from a specialist in whom you have confidence. Large emeralds in particular should only be purchased with a report from a reputable gemological institute. Such an institute will be able, thanks to the most modern examination techniques, to differentiate reliably between natural and synthetic emeralds, and will inform you as to whether the stone has undergone any treatment of the kind a purchaser has the right to know about.
And one more piece of advice on the purchase of an emerald: whilst diamonds generously scintillate their fire in sizes below 1 carat, you should go for larger dimensions when acquiring a colored gemstone. True, there are some lovely pieces of jewelry with small colored gems to set decorative accents, but emeralds, like other colored gemstones, do not really begin to show that beautiful glow below a certain size. How large ‘your’ emerald ends up will depend on your personal taste, and on your budget. Really large specimens of top quality are rare. This means that the price of a top-quality emerald may be higher than that of a diamond of the same weight. The fascination exuded by a fine emerald is simply unique.
