The emerald cut was originally developed in the 16th century for emeralds to prevent the rough stone from chipping during the cutting process. This step-cut style highlights the gem's color while simultaneously protecting the stone.
Diamond cutters subsequently adopted the emerald cut; colored diamonds, in particular, are well-suited to this style due to their color characteristics. The cut's stepped structure creates unique optical effects.
Because emerald-cut diamonds feature a large table, inclusions are relatively more visible; consequently, high clarity is required, with common choices ranging from VS2 and above or the VS grade. Regarding color, common choices are H-color or better, or G-color and above. In terms of proportions, a depth percentage between 60% and 65% and a length-to-width ratio of approximately 1.5:1 are typical specifications.
