Emerald is the green assortment of the mineral beryl. The amazing green color of emerald is unique in the gem dominion. Emerald's dear green color is due to small quantities of chromium and boosted by traces of iron. Unlike any other beryl’s, emeralds frequently contain inclusions and other flaws. These flaws aren't looked on as negative aspects for emerald like they'd be for other gemstones. Indeed, these issues are considered part of the personality of the stone and are used to reassure the buyer of a natural stone. However, splinters and inclusions are so typical in emeralds that their toughness is influenced - emeralds have a tendency to break easier than other beryl’s.
Virtually all emerald gemstones have been treated to enhance their appearance. Traditionally , gems were "oiled" which filled up the cracks and veils with a clear oil, effectively hiding the failing. Sadly , oils have a tendency to evaporate over time so that oil-treated emeralds have a tendency to look worse over a period of time. Fortunately, the treatment might be repeated to good effect. Recently, the cracks are stuffed with an everlasting epoxy so evaporation of oil isn't a problem. Actually, you should be expecting an emerald to be dealt with. Note that oil treatments are regarded as satisfactory in the gem trade, unless colored oils are used to change the color. For fine gemstones, treatments are required to be divulged by the U.S. Federal Trade Commission.
