Emerald Cut Diamond Guide

The emerald diamond has a rectangular shape with length to width ratio varying from 1.5 to 1 or 1.7 to 1. Typically, the number of facets in emerald diamond may vary from 50 – 58 facets. The exact number of facets in the emerald diamond depends on the number of rows on the diamond crown and the diamond’s pavilion. Emerald cut diamonds have the edges trimmed and the facets are usually parallel to the diamond girdle.

The emerald diamond is a brilliant diamond but when compared to other diamond cuts like the round or princess cuts, the emerald is less brilliant than them but it has a subtle spark that the other diamonds lack. This is why the emphasis of the emerald diamond is not on the diamond’s brilliance but on the diamond clarity. When the emerald diamond is viewed from the top, it displays an “on and off” pattern that is commonly seen in diamonds with small facets. The “hall of mirrors effect” is a pattern that is commonly seen in emerald diamond because it is a step cut diamond.

The elongated shape of the emerald diamond makes it appear bigger and longer than other diamonds of the same size. It also creates an illusion on the fingers of whoever wears them, making the fingers thinner and longer.

The table of the emerald diamond ranges from 61-68% and the ideal depth is between 60-65%. A little amount of the original stone is lost when cutting the diamond and this influences the diamond price in the market.

The emerald diamond is known to be an unforgiving diamond cut that exposes whatever color or inclusions that is in the diamond. The emerald diamond therefore requires a high level of perfection both for the cut and color of the diamond because impurities in the diamond can be easily noticed. The attractiveness of this diamond is very much related to the quality of the diamond color and clarity. The most important thing when buying an emerald diamond is to ensure that the diamond is eye clean. If there is a little impurity in it, it is best that you avoid it. 

According to the GIA, there is no grading for the cut of the emerald diamond. So if you come across a cut grade for emerald diamond, it is not from GIA (the most trusted body), so you have to be careful and pay more attention.
