Diamond Cut Statistics

As per the statistics, less than 3.5% of the diamonds sold globally are emerald cut. These diamonds are cut in a unique manner, which is also called step cut. While most of the diamond shapes have small and brilliant facets, emerald cut diamonds have long and narrow facets. The faceting pattern of the diamond results in flashes of light, which is also termed as the hall of mirror effect. The hall of mirror effect creates flashes of light and dark planes inside the step or facet.

Color Recommendations

The color grade is the term used to refer to the amount of color or lack of color that the emerald cut diamond shows. Usually, the emerald cut diamonds reveal color much easily when compared to the other diamond cuts and shapes, as the step cuts do not hide the color of the diamond as much as the brilliant cuts. This is not a big thing to worry about. However, you need to consider getting one color grade higher than what you would buy in a different diamond shape, say round cut.

The good news is that the smaller emerald cut diamonds are capable of hiding the color better than the larger ones. Therefore, depending on the size of the diamond that you are planning to buy, you may not have to buy a colorless (D – F) diamond, even if you were looking for a colorless diamond. The below chart can help you decide the color range of the emerald cut diamond that you need to buy based on grading like colorless diamonds, limited color diamonds, and warmer diamonds.

This ratio is obtained by dividing the length of the diamond by its width and can help understand how wide or skinny the diamond is. The larger the length to width ratio of the diamond, the diamond will be much longer than its width, meaning that the diamond will look more rectangular. If the length to width ratio is smaller, then the length of the diamond will not be much larger than its width, meaning that the diamond will look squarer. As per the experts, it is better to go for diamonds with length to width ratio between 1.30 and 1.40.
