Description characteristic of the mineral.
Bright-green variety of beryl. Bright-green quite transparent variety of beryl, which be found rarely and valued ever-higher (can outvalue diamond). It stone precious not only at price but also on the properties. One of dearest Beryls is an emerald of intense-green, that Beryl, painted a chrome. It differs from an ordinary green beryl that green Beryl - pale, his colouring is created the admixtures of ferrous iron or vanadium, but not chrome. Hardness Mohs of beryl varies from 7,5 to 8, thus emerald some more soft, than other varieties. Shallow inclusion no appearance is not diminish the cost of stone. The green Beryl emerald of rich deep green colour even with including is valued more than the cleanest emerald (Beryl) of inconspicuous-green color. The synthetic emeralds of hydatogenesis usually contain shallow liquid or gaseous inclusion. Natural emeralds often have inclusion plates and microlamella of mica and crystals of Pyrite (an even shivy mica natural emerald is far dearer than the ideal synthetic analogue).
Emerald - wonderful and favourite at all times jeweller stone. Emeralds were known as early as Ancient Egypt and Babylon. During many centuries the deposits of emeralds were developed in Colombia. Europeans knew about the remarkable stone of South America in XVI century in connection with the conquering hikes of Spanish conquistadors. Presently about 180 deposits of emerald are known in Colombia. The emeralds of Colombia are given by a from 55% to 90% world booty. Considerable on scales deposits of Brazil, which give the about fourth of world booty of emeralds presently. The deposits of emeralds in India were known from old times, but to beginning of XX century they lost the former value. The booty of emerald is conducted and in Pakistan and other regions of earth.
The sizes of crystals of emerald are different: crystals of jeweller quality more frequent than all shallow. Intensity of colouring of emeralds is different. On jeweller business emeralds are used from weak green to the thick juicy emerald color. At identical the degree of transparency, imperfectness (presence of cracks and including) and size cost of stone the higher, than more intensive his colouring, thus there is a payup stone of different tints of color of substantial. Intensity of colouring is related to maintenance of admixture of chrome. The emeralds of different deposits differ the different tints of green color. So, for the Colombian emeralds a bluish tint is characteristic, for Ural and north-american - easy rather yellow or bluish. Possibly, some influence on the tints of green color of emerald can render the admixture of vanadium.
Often there is the zonal colouring in emeralds. There are crystals with the poorly painted peripheral and intensively painted green central part and vice versa. Other type of zonality is a change intensity of colouring along the long ax of crystal, a few remittent bars of different intensity are thus visible. Sometimes crystals are painted unevenly. Colouring of emerald is steady and does not change under act of light and heat. However at heating to 700-800oC crystals a few grow pale. All of large crystals, as a rule, are turbid and opaque. They contain inclusion of shallow scales of mica or needles of jetstone. At the best the sharp eye of specialist can find out in them centimetre areas, suitable for cutting. Mica is an admixture, distinguishing an emerald from other stone.
His property gives liveliness and game an emerald a few to change the tint of color at the turn of stone. You will look across a crystal is he yellowish-green, warm, fresh, will turn and will look along an ax - the characteristic appeared emerald in blue. All of beryls possess, but it is almost unnoticeable at pale-colored crystals, and at emeralds often shows up expressly.
For treatment of transparent emeralds use the followings types of cutting: step, rectangular emerald (square), rarer diamond. Stone the semilucent are processed in form cabochons. It is necessary to notice, what only very insignificant part of emeralds is processed in those countries, where they are obtained. In jeweller wares dear emeralds often combine with colourless diamonds, to underline the road of intense-green stone.
As imitations apply the minerals of green color, less dear and more widespread - Corundum, dioptase, Chromediopside, Tourmaline, Grossuliare, chrysolite, hiddenite, jade, jadeite, Zircon, Fluorite, chrysoprase. In Burma and CIS present wonderful emerald-green color of Chromediopside, which for us is often given out for an emerald. Dear Uvarovite (large crystals), Demantoide and Ural Alexandrite it is also possible to entangle with an emerald, but at price they comparable. Emerald-green Garnet Uvarovite from very pony-size of crystals extremely rarely be found in the cut kind.
The cases of pseudo-refining pseudo-upclassing of rough ground, broken rock emeralds and Beryls are known by saturating with their butter with dyes. Such stone can be exposed, loading them in water, containing the solvent of fat (for example, domestic detergent or liquid for fat doing dishes in cold water). Recommend also slightly to warm up stone, deleting butter from cracks, but in home terms it doing is extremely undesirable (more safely to wash suspicious stone in domestic solution).

SYNTHETIC EMERALD. In the last decades, besides plenty of hydrothermal rubies and Sapphires, most synthetic emeralds also got a hydrothermal method. For such emeralds tubular inclusion, brownish inclusion oxides of ferrous iron is characteristic. In ordinary jeweller shops, distinguishing natural emeralds from synthetic is possible coming from that most natural emeralds in our jeweller wares unperfect, have cracks and visible an eye internal defects, uneven colouring, placed opaque. On labels the synthetic origin of emeralds is not specified. Too inconspicuous painted stone can come to light a not emerald, but ordinary beryl.
It is better to pass perfect rifle-green and ideally transparent identical in color emeralds on an analysis independent specialists, because probability is too high to purchase very high-quality synthetic materials, given out for natural stone (especially in the imported gold wares). Synthetic emeralds have the very characteristic saturated sky-green color which gives out their origin partly, although much the same some Colombian emeralds have a tint. The synthetic emeralds of hydatogenesis usually contain shallow liquid or gaseous inclusion. Natural emeralds often have inclusion plates and microlamella of mica and crystals of Pyrite (an even shivy mica natural emerald is far dearer than the ideal synthetic analogue). At a choice, that to purchase: green synthetic Zircon or synthetic emerald a preference needs to be on possibility given an emerald, because he is far more beautiful and more lasting.
There is another variety of emerald which is in the intermediate stage between synthetic and ennobled. They are unjeweller beryls, not presenting in the feedstock of jeweller value, but covered the layer of grow lengthen of synthetic emerald in thick from 0,3 mm and more. Color of such stone of inconspicuous-green. At the use of popular today hydrothermal method the layer of emerald in 0,8 mm thick grows for days. The structure of stone is imperfect, cracks and structure of stone as though are underline. Stone are opaque or check with x-rays (Roentgen), characterized crackedformes lines in a superficial layer, which look at immersion in a liquid as thin intensive-green rim. Silverwares, studded such ennobled beryls, appear in jeweller shops. In shops the dearest giant dome-shaped silver ring, strewed these ennobled beryls, is costed by about 200 US dollar, small rings with a few stone cost to 50 US dollar.
