Perfect Clarity and Style of the Emerald Cut Diamond
The Emerald-Cut diamond is so named because this cut was, originally, used only on emeralds.
It is called a step-cut, which is the cut most commonly used on square or rectangular diamonds. Due to its larger, open table, this shape highlights the clarity of a diamond.
If you choose an emerald-cut with a lower clarity grade, such as SI, be sure to review the clarity plot on the diamond certificate.
Also, emerald-cut diamonds can vary greatly in how rectangular they are.
To get a traditional emerald cut the length needs to be more than the width.
Polish and symmetry are two important aspects of the cut.
The polish grade describes the smoothness of the diamond’s facets, and the symmetry grade refers to alignment of the facets.
With poor polish, the surface of a facet can be dulled, and may create blurred or dulled sparkle. It may constantly look like it needs to be cleaned.
With poor symmetry, light can be misdirected as it enters and exits the diamond.
