African Emerald is like all coloured gemstone. We can say that there is four type of gems find Color, Cut, Clarity and Crystal. Emerald (Be3Al2Si6O18) is the grass-green type of Beryl. The formation of emerald involves a natural process known as exometamorphism.
Normally, in the grading of colored gemstones, color is by far the most important criterion. However, in the grading of emerald, crystal is considered a close second. Both are necessary conditions. A fine emerald must possess not only a pure verdant green hue as described below, but also a high degree of transparency to be considered a top gem.
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.
green of the emerald is a colour which conveys harmony, love of Nature and elemental joie de vivre. The human eye can never see enough of this unique colour. Pliny commented that green gladdened the eye without tiring it.
Property of Emerald, the refractive indices and SG vary perceptibly according to the locality where it is mined, due to variations in chemical composition. The inclusions, also, are often distinctive for each locality, and Gemologists will do well to familiarize themselves with these things if they wish to distinguish between the Emeralds of one mine from another.
Color is divided into three components: Hue, Saturation and Tone. The hue must be bright. Gray is the normal saturation modifier or mask found in Emerald. A grayish green hue is a dull green.
Brazil has been supplying Emeralds to the world market since the 1980s. Typical Brazilian emeralds are Lighter and Yellowish. Emeralds from Zimbabwe are smaller is size and lighter in shade. However the term 'African emerald' is a misnomer. It simply denotes Green Fluorite.
The presence of chromium in emerald is the absorption spectrum it displays, which is distinctive enough to enable the stone to be distinguished from any other gem species.
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 crystallised out to make one of our most beautiful gemstones.
The Swat emeralds show light red to red through the Chelsea color filter and completely absorb short-wave ultra-violet radiation.
This gives the rock its gemlike green color. Varying amount of iron also alters the color of the rock. It has a hardness of 7.5-8 and a refractive index of 1.57-1.59. However it is not a gem recommended for 'everyday' use since it falls in the category of soft stone.
A chemical analysis shows that chromium (which is the cause of the green of emerald) and iron are prominent constituents in Swat emeralds. The presence of relatively high iron content means that the emeralds from Swat do not show so red a fluresence as some other emeralds as iron acts as a fluresence quencher.
The cut of the stone is also significant. Emerald can have round, pear, oval shapes the emerald cut, that is, octagonal shape is most preferred. Inclusions are almost an accepted fact in emeralds.
Deposits of the stone are also found in other parts of the world such as in Zambia, Zimbabwe, Madagascar and Nigeria. However Columbia and Brazil are the leading producers of emerald today. The mines of Egypt, which supplied emeralds to Cleopatra, are not much into production today. Among the foremost consumers of emerald are USA and Japan who buy 75% of the world's cut emerald.

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.
So how can you protect yourself from these 'fakes'? best way is to buy from a specialist in whom you have confidence. Emerald should only be purchased with a report from a reputable gemmological institute. You can differentiate reliably between natural and synthetic emeralds.
