Emerald Color
With emeralds, even more so than other colored gems, it is the color that is the chief determinant of value. By definition, emeralds are a medium to darker green to blue-green and sometimes slightly yellowish-green beryl. Emeralds owe their fine green color to traces of chromium and/or vanadium impurities. The most popular and valuable color is a slightly bluish green in a medium dark tone with strong to vivid saturation, however, too much blue can decrease the value.
The term "Colombian emeralds" is often used to describe vivid, slightly bluish-green stones of a medium to medium dark color, regardless of their geographic origin. Emeralds of a lighter color are sometimes called "Brazilian emeralds", even if they were mined in Africa.
Emerald Clarity and Luster
Emeralds have a vitreous (glass-like) luster when cut and polished. Although their clarity can occur from translucent to opaque, transparent specimens are most desirable and are much more valuable. Clarity is important, but inclusions are tolerated more in emeralds than virtually any other gem. Unlike other beryl gems, emeralds often contain inclusions and other flaws. These flaws are not looked upon as negative attributes for emeralds, as they would be for other gemstones. Indeed, these flaws are considered part of the character of the stone and are used to assure the purchaser of a natural stone.
Emerald clarity is graded by eye, unlike diamond, where 10x loupe magnification is used to grade clarity. If an emerald has no inclusions that are visible to the naked eye, it is considered flawless. "Eye-clean" stones will command the highest prices, especially those with ideal color grade.
Emerald Cut and Shape
Emeralds are most often cut in a special cut designed just for this gem; "the emerald cutt". The emerald cut is a step cut or trap-cut featuring a rectangular or square shape with truncated corners. This cutting style maximizes the beauty and color of the stone, whilst protecting it from mechanical strain and internal stress. Emeralds are also cut into a variety of other traditional shapes such as pear, oval and round. Lower grade materials are often cut en cabochon or into beads. Highly transparent and clear materials are sometimes cut in brilliant-style.
