Emerald Guide
Emerald is the bluish to green to green variety of beryl family of minerals. Color is the biggest factor in establishing the value and quality in natural emeralds. Emeralds come in a range of green shade. from light to dark with tints of other colors ranging from yellow to blue. The most desirable emerald colors are bluish green to pure green with vivid color saturation and the tone that is not too light or too dark. The color is evenly distributed. If the hue is too yellowish or too bluish, the stone is of a different variety of beryl.
Emeralds by nature contain inclusions that are visible to the unaided eye. The trade generally accepts eye-visible inclusions but when the inclusions have a negative effect on transparency and clarity, or compromise the durability of a stone, they can lessen the value. Eye-clean emeralds are especially valuable because they’re so rare. However, any emerald without inclusion or appears flawless could be suspected to be synthetic or simulant.
