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.
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.
