Emerald like all Gemstones, is valued according to its Color, Cut, Clarity and Crystal. Emerald is the grass-green type of Beryl.
Normally, in the grading of 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 vibrant green hue, but also a high degree of transparency to be considered a top Gemstone.
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 Gemstone recommended for 'everyday' rough use since it falls in the category of soft stone.
A chemical analysis of an Emerald 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 fluorescence as some other Emeralds as iron acts as a fluorescence quencher.
The cut of the stone is also significant. Emerald can have round, pear, oval shapes and the famous Emerald cut i.e., Octagonal Cut is most preferred. Inclusions are almost an accepted fact in emeralds. A skillful gem cutter is able to hide the inclusions while cutting a Gemstone and bring out its colour and glitter.
San Francisco chemist Carroll Chatham, are manufactured by a number of producers and by several different processes. The process used by Gilson, lennix, chathan, inamori and zerfass is the flus fusion method, involving crystallization of the beryl constituents from a melt in some suitable solvent such as lead molybdate. And then stone shows refractive indices birefringence, and SG markedly lower than those for natural emeralds and to have a stronger red appearance.
