Faceted

Facets are flat faces on geometric shapes. The organization of naturally occurring facets was key to early developments in crystallography, since they reflect the underlying symmetry of the crystal structure. Gemstones commonly have facets cut into them in order to improve their appearance.

Of the many hundreds of facet arrangements that have been used, the most famous is probably the round brilliant cut, used for diamond and many colored gemstones. This arrangement of 57 facets was calculated by Marcel Tolkowsky in 1919. Slight improvements have been made since then, including the addition of a 58th facet (a culet) on the bottom of the stone. Since this is calculated to show maximum brilliance, round diamonds are rarely cut in any other arrangement, although recently the Princess cut is becoming popular. Other cuts, including "rose" cuts, are most typically found in antique jewelry. See diamond cuts for an in-depth discussion and diagrams of various shapes and ways of cutting faceted stones.

The art of cutting a gem with facets is a very precise activity. The aim with a faceted cut is to produce an article that sparkles with internally reflected light, and that shows off the "fire" of the stone. Accordingly, only transparent or translucent stones are usually faceted.

The angles between each facet are precisely calculated. As the aim is to maximise the effect of the internal reflections, these angles depend on the refractive index of the material. This means that although the name and general shape of a particular cut may be the same between different materials, the actual angles will be slightly different, for the maximum effect.

Thus, although cubic zirconia and rock crystal may look similar to diamond, and all can be cut in a round brilliant cut, the angles must be different to produce the same optical effects. Additionally, as diamond has a refractive index significantly higher than the other natural transparent stones, it can have a much greater sparkle than other materials.

While some facets can be cut by cleavage, specialised machines are used for cutting arbitrary facets. These consist of two main features:

a flat abrasive, usually diamond dust of precise size bonded onto a metal disk (called 'laps') or carried by an oily fluid on a smooth metal or ceramic disk, and
a system for holding a stone onto the disk at a precise angle and position.
This usually requires the stone to be attached to a holder or dop, which is then placed in an indexed vice. This allows progressively finer abrasives to be used without disrupting the orientation of the stone. The final abrasive must be smaller than the wavelength of light, so that the scratches it creates are invisible. Modern machines tend to have indexed gears for moving the stone, so that rotating the stone to cut the next facet can be more precisely controlled.

An older machine called the jamb peg faceting machine used wooden dop sticks of precise length. By placing one end into one of many precisely located holes in the jamb peg, the other end, with the stone, could be precisely placed onto the lap. These machines took considerable skill to use effectively.

Much less commonly, faceters use cylindrical machines, which leave concave facets. This technique is most noticeably used around the gem's girdle.

Tourmalines are precious stones displaying a unique splendour of colours. According to an ancient Egyptian legend this is the result of the fact that on the long way from the Earths heart up towards the sun, Tourmaline travelled along a rainbow. And on its way it collected all the colours of the rainbow. This is why nowadays it is called the "Rainbow gemstone".


However, the name "Tourmaline" has been derived from the Singhalese expression "tura mali", which translates as "stone of mixed colours". The very name already refers to the unique spectrum of colours displayed by this gemstone, which is second to none in the realm of precious stones. Tourmalines are red and green, range from blue to yellow. Often they show two or more colours and are cherished for this parti- or multi-coloured appearance. There are Tourmalines which change their colour from daylight to artificial light, others display chattoyance. No Tourmaline exactly resembles another one: this gemstone shows many faces and is thus excellently suited to match all moods and tempers. It does not come as a surprise, then, that ever since ancient days it has been attributed with magical powers. Tourmaline is supposed to be an especially powerful influence on love and friendship, lending them permanence and stability.


In order to understand this multitude of colours you will have to polish up your knowledge of gemmology: Tourmalines are mixed of complex aluminium-borosilicate varying in their composition. The slightest changes in composition will result in completely different colours. In fact, showing one colour only are quite rare; generally one and the same crystal displays several shades and colours. Not only the wide range of colours characterises this gemstone, it also shows a remarkable dichroism. Depending on the angle of view the colour will be different or at least show different intensity. The deepest colour always appears along the main axis, a fact that the gemstone cutter has to keep in mind when cutting the stone. This gemstone is excellently suited for wearing and is uncomplicated to care for, since all Tourmalines show a hardness of 7 to 7.5 on the Mohs scale. Thus Tourmaline is an interesting gemstone in many aspects indeed.


The different shades of colour have been assigned different names in the trade. For example, deep red Tourmaline is named "Rubellite", provided it shows the same fine -red shade in daylight and in artificial light. Should the colour change when the source of light changes, the stone will be called a "Pink Tourmaline". Blue Tourmalines are called "Indigolith", "Dravite" is a golden-brown to dark brown Tourmaline, and black Tourmalines are known as "Schorl". The latter stone is mainly used for engravings and in esotericism, where it is highly cherished because it is reputed to ward off harmful radiation from its wearer.

Pink Tourmaline
The color pink is associated with love and other matters of the heart, and pink tourmaline is the quintessential heart-chakra stone. It is a representative of the feminine, or yin energies. It is unsurpassed as a gemstone aid in healing old emotional wounds, particularly those of childhood. It emanates a soft, soothing energy that engenders feelings of comfort, safety and nurturance. In meditation, one should hold or place a pink tourmaline upon the heart chakra, visualizing a pink light radiating from the stone and ultimately encompassing the body in a pink cloud or bubble. This will infuse the entire emotional body with love and can restore a sense of wholeness.

Pink Tourmaline can be used to repair 'holes' in the auric field created by negative attachments or past abuse. Wearing or carrying a pink tourmaline crystal or gem through the day can assist one in releasing stress, worries, depression and anxiety. These crystals can help the emotionally 'numb' recover their passion and zest for life. They strengthen the link between the heart and crown chakras, opening the pathway for infusion of the heart with the highest Divine energies. They can help the timid find the courage to love, and they can increase the trait of gentleness in most individuals. Wearing Pink Tourmaline turns one into a beacon of its loving and healing energies, making it more difficult for others to project negativity in one's direction and often influencing them towards greater kindness and tolerance.

Pink Tourmaline supports emotional healing and the activation of the heart chakra. It stimulates feelings of joy, happiness and  relaxation. Due to its high lithium content, it is a powerful calming stone that can calm the emotions and the physical body. It is a partner to Black Tourmaline in relieving stress and diffusing worry or obsessive behavior. In meditation, Pink Tourmaline can aid in clearing and purifying the emotional body. It helps identify emotional patterns no longer aligned with one's spiritual growth and can assist in changing these patterns to reflect higher approaches to relationship and communication.

Pink Tourmaline is an excellent stone for children-particularly the spiritually sensitive 'Indigos'-because it provides a centering, calming energy that can assist them in considering consequence and karma before taking action.


SPIRITUAL   Pink Tourmaline activates the high-heart center and one's ability to surrender to Love. It helps one find strength in vulnerability and feel joy in all one's learning experiences.

EMOTIONAL   Pink Tourmaline is a powerful emotional imbalance and cleanser. It is one of the strongest stones for alleviating stress and the emotional imbalances that can stem from that state. It is a powerful stone for children, especially when hyperactivity or difficulty sleeping is an issue.

PHYSICAL   Pink Tourmaline helps calm and soothe the heart, assisting with angina, irregular heartbeat and recovery from heart attack. It is useful in balancing brain biochemistry to help promote a balanced mental state.


Very popular is "Verdelith", the green Tourmaline, however, if its fine -like green is caused by traces of chromium, the stone is named "Chromium-Tourmaline". But the outstanding highlight among Tourmalines is of course Paraiba Tourmaline, a gemstone showing a vivid deep blue to bluish green, found for the first time in1987 in the mines of the Brazilian state of Paraiba. In good qualities these stones are much coveted treasures. Since yellow Tourmalines from Malawi of brilliant colour have been offered on the market, the formerly missing colour yellow has been added in excellent quality to the apparently unlimited range of colours shown by the "Rainbow Gemstone".


These are by no means all the names Tourmaline has achieved: there still have to be mentioned bi-coloured and multi-coloured Tourmalines Very popular are also slices cut as cross-sections through Tourmalines, as these will render the full splendour of colours embedded in a specific Tourmaline. For example, such slices taken from Tourmalines with red heart and green border are called a "Watermelon-Tourmaline"; slices with a clear heart and a black border are called "Moors head Tourmaline".

Tourmalines are mined everywhere in the world. There are important occurrences in Brazil, in Sri Lanka and South and Southwest Africa. Other occurrences are situated in Nigeria, Zimbabwe, Kenya, Tanzania, Mozambique and Madagascar, Pakistan and Afghanistan. Tourmalines are also found in the USA, first of all in Maine and Utah. But although there are rich occurrences of Tourmalines all over the world, good qualities and fine colours are only rarely offered on the market. Therefore, then, the price range achieved by Tourmaline almost matches its wide range of colours.



Emerald

Emeralds are fascinating gemstones. They show the most beautiful, deepest and most brilliant green imaginable: Emerald green. Inclusions are allowed, and nevertheless, in top qualities fine Emerald are even more valuable than diamonds.


The name Emerald was derived from French "esmeraude" which in turn goes back via Latin to the Greek root "smaragdos", meaning simply "green gemstone". There are uncountable adventure stories involving this splendid gemstone. Even the ancient Incas and Aztecs in South America, where the best Emeralds are still being found today, worshipped it as a holy stone. However, probably the most ancient occurrences which were known are located near the Red Sea. These gemstone mines were already exploited by Egyptian Pharaohs between 3000 and 1500 B.C., gained fame under he name of "Cleopatra's Mines", but had already run out when they were rediscovered.

Many centuries ago in the Veda, the ancient sacred writings of Hinduism, there was written down information on the valuable green gemstones and their healing power: "Emeralds promise good luck", or "The Emerald enhances your well-being". It does not come as a surprise, then, that the treasure chests of Indian Maharajas and Maharanis contained most wonderful Emeralds. One of the largest Emeralds in the world is the "Mogul Emerald". It goes back to the year 1695, weighs 217.80 carats and is about 10 cm high. One side is inscribed with prayers, on the other side there are engraved opulent flower ornaments. The legendary Emerald was auctioned off at Christie's of London for 2.2 million US dollars to an anonymous buyer.

Emeralds have been coveted ever since ancient times. Some of the most famous Emeralds can therefore be admired in museums and collections. For example, The New York Museum of Natural History not only shows a cup from pure Emerald which was owned by Emperor Jehingar, but also a Colombian Emerald crystal weighing 632 carats. The collection owned by the Bank of Bogota contains no less than five valuable Emerald weighing between 220 and 1796 carats. Also in the Irani State Treasure there are guarded some wonderful Emeralds, among them the tiara of ex-Empress Farah.

Green of Life and of Light

Emerald green is the colour of life and of eternally returning spring. For centuries, however, it has also been the colour of beauty and of eternal love. Even in ancient Rome green was the colour dedicated to Venus, goddess of love and beauty. Today there are still many cultures and religions where green holds a special position. For example, green is the holy colour of Islam. All states of the Arabian league sport green banners symbolising the unity of their religion. But also within the Catholic church green holds an important status, as among the liturgy colours green is considered the most natural and elementary one.

Splendid Emerald green is a colour communicating harmony, love of nature and a primeval joy of life. You cannot ever get too much of this unique colour, as Pliny already pointed out "Green is pleasant to the eye without tiring it.". Green is characterised as fresh and full of life, never as monotonous. And as this colour keeps on changing gradually between bright daylight and artificial lamplight, Emerald green in all its hues and shades will preserve its vivid energy.


Fingerprints of Nature

The vivid brilliance of its colour makes Emerald a unique gemstone indeed. But really good qualities are rare, as inclusions will often spoil the impression - traces of an active history of origin characterising the gemstone. Fine inclusions, after all, do not diminish the value; on the contrary. An Emerald of deep, vivid green with inclusions will be valued higher than an inclusion-free stone of paler colour. Almost endearingly, experts call the many crystal inclusions or fissures which are so typical for this gemstone a "jardin". The tender green plant-like structures in the Emerald garden are considered as identifying characteristics of a naturally grown Emerald.

Where do they come from and why are they acceptable? In order to answer this question we must look back in history over 65 million years to the times when Emeralds were created. From a chemical-mineralogical point of view, Emeralds are beryllium aluminium silicates achieving the good hardness of 7.5 to 8. Like blue , pale pink Morganite, golden Heliodor and pale green Beryl, Emerald is also a member the Beryl gemstone family. Pure Beryl is colourless. Colours only exist when traces of certain elements are added in the process. For Emerald, traces of chrome are mainly responsible for the fascinating colour. These elements usually occur concentrated in the Earth crust at completely different locations from beryllium, and therefore Emeralds should not exist at all. However, in the course of extreme tectonic processes these contrary elements were brought together and created one of our most beautiful in the process of crystallising under enormous heat and high pressure. Due to the tensions involved in the geological conditions there occurred several smaller or larger disturbances during creation. And a view inside the heart of an Emerald, with a magnifying glass or a microscope, will tell us something about the wild and vivid process of creating this unique jewel: there may be smaller or larger fissures recognisable, perhaps there will be a miniature crystal or a small bubble within, and a variety of structures may be discerned. Some of these phenomena had the time to heal out in the growth phase and show the serrated three-phase-inclusions, which are so typical for Colombian emeralds: cavities filled with liquid, often containing also a small gas bubble and tiny.

Obeying the laws of logic, such a history of creation makes it virtually impossible for larger to grow without imperfections. Therefore, then, it is a rare event indeed when a larger emerald of good colour and good transparency is found. And this is why such fine Emeralds are so valuable. But the very fact that Emeralds have a vivid past mean that we like to see traces of this in the stone - provided there is only a fine "jardin" apparent in the stone, and not a wildly overgrown and untamed jungle of a garden, which negatively effects colour and transparency.

The World of Fine Emeralds

Colombia is still the main country of occurrence for fine Emeralds. About 150 mining sites are known there, but not all of these are currently being exploited. The most famous names in this context are Muzo and Chivor, where even in pre-Colombian times the Incas mined Emeralds. The economically most important mine is Coscuez. Estimates ascribe about three quarters of the current Colombian emerald production to the about 60 locations belonging to the Coscuez mine. Colombian Emeralds are set apart from Emeralds of other origin by their especially fine and brilliant green which is not influenced by any bluish tinge. Depending on the place of occurrence, the colour of Emerald may vary. This fascinatingly beautiful colour is highly coveted in the international Emerald trade, so that even visible inclusions which can be discerned with the mere eye are acceptable. But Colombia has more to offer: from Colombian Emerald mines occasionally there come Emerald rarities on the market, like "Trapiche-emeralds" displaying a six-ray-star , or like the extremely rare Emerald Cat's Eye.

Although undoubtedly the best and finest qualities of emeralds are from Colombia, it would be wrong to suppose that the "birthplace" of a stone automatically guarantees immaculate quality. Fine emeralds are also found in other countries such as the Zambia, Brazil, Zimbabwe, Madagascar, Pakistan, India, Afghanistan or Russia. Mainly Zambia, Zimbabwe and Brazil have gained an international reputation for fine Emeralds. From Zambia there are exported excellent Emerald in a beautiful, deep emerald green showing good transparency. Their colour is usually darker than that of Colombian stones and often has a fine bluish undertone. From Zimbabwe's famous Sandawana mines there come usually smaller, but very fine Emeralds in a vivid and deep green, often with a slight yellowish-green shade. Brazil's gemstone mine Nova Era at present even challenges the famous Colombian Emerald mines: their production of Emeralds in beautiful shades of green compete in their attractive beauty with the gemstones offered by the neighbouring country. Because of the occurrences found in Africa and Brazil, Emeralds are fortunately available in larger amounts today than in earlier times - much to the pleasure of their fans.


A Capricious Gemstone

The good hardness may well protect Emeralds from scratches to some extent, but its brittle structure and the many fissures can make cutting, setting and cleaning the stone somewhat problematic. Cutting Emeralds always means a new challenge even for experienced cutters, on the one hand because of the high value of the rough crystal involved, on the other hand because of the frequent inclusions. But this does not diminish their fascination with the unique gemstone. They have developed a special cut, especially for Emeralds: the so-called emerald-cut. The clear design of the rectangular or square cut with its bevelled edges underlines the beauty of the valuable gemstone perfectly, while at the same time offering protection from mechanical strain. Emeralds, however, are also cut in many other, usually classical shapes. But if the raw material is veined by a multitude of inclusions, it is often cut as softly rounded cabochon or as Emerald pearls, which are especially popular in India.

Many Emeralds today are treated with oils or natural resins. This is customary in the trade, but it has the effect that the green jewels react often quite sensitively to in-expert treatment. For example, they must not be cleaned ultrasonically. The substances used by the cutter in the process of cutting or applied subsequently seal the fine openings on the surface of the gemstone and these would be removed in the course of such a cleaning procedure - resulting in a rather matted gemstone. Therefore Emerald rings should always be removed before the hands are immersed in any kind of detergent.

A Question of Trust

As Emerald is not only one of the most beautiful gemstones, but also one of the most valuable ones, there are unfortunately a multitude of syntheses and imitations. How can you feel safe that you do not fall for one of these impostors? The best strategy here is to buy your gemstone from an expert of your trust. Especially larger emeralds should only be purchased with an accompanying certificate provided by a renowned gemmological institute, where modern methods of analysis will be employed to assess a stone and separate natural from synthetic Emeralds, and where you will be informed about any treatments the stone was subjected to that you should know about.

And now a last piece of advice for buying Emeralds: other than diamonds, which show their sparkling brilliance even in sizes below one carat, a coloured gemstone should be preferred in larger sizes. There does exist beautiful jewellery set with smaller coloured stones as decorative accents, but Emeralds like other coloured gemstones will best display their brilliance in larger dimensions. How big your perfect Emerald should be - this depends on your personal preferences and also on your purse. Really big Emeralds of good quality are rare. In these cases the price for an Emerald of top quality will be higher than the price for an equally large diamond of the same weight. After all - Emerald is a gemstone with a unique fascination.
