Fun Facts : Emeralds, like all colored gemstones, are graded using four basic parameters–the four Cs of Connoisseurship: Color, Clarity, Cut and Carat weight. Before the 20th century, jewelers used the term water, as in "a gem of the finest water", to express the combination of two qualities: color and clarity. Normally, in the grading of colored gemstones, color is by far the most important criterion.
