Emerald Cut Diamonds

The Emerald cut diamond is an embodiment of beauty and in every sense feminine and unique. It ensues an aura of royalty and gracefulness that is, perhaps, not found in any other diamond cut. It is rectangular in shape, enhanced with step cut, truncated corners and flat and large facets. When viewed from the top, the stone resembles stair steps and delivers a hall-of-mirrors effect that comes with the interchange of dark and light planes. Though the rows of facets can vary in number for both the crown and pavilion, the emerald cut is generally comprised of 57 facets with 25 on the crown and 32 on the pavilion. In comparison to the brilliant cut, the emerald cut diamond has less fire and brilliance. But a striking factor of this cut is that the very shape reveals the clarity or in other words, one can see the imperfections and flaws if any, very clearly. Hence, when you go for an emerald cut, it is recommended to select the highest feasible grade.

An emerald diamond should ideally have a minimum ratio of 1.3 and a maximum of 1.6, though the classic emerald cut diamond has a length to width ratio of 1.50. The elongated shape of the diamond makes the wearer’s finger appear much longer. What’s more, an emerald cut diamond appears larger because an average 1 carat emerald cut will have 5% greater surface area when compared to a 1 carat round cut diamond. Though they are rare, comprising of just 3% of all the diamonds in the world, they are also less expensive because of their less demand. They have a very subtle sparkle, which is different from the sparkle of all the other diamond cuts.

 History of Emerald Cut Diamond:

The origin of the emerald cut diamond is not clearly known, but traces of its specifications can be found in the single table cuts and in the multi-faceted table cuts belonging to the Art Deco period of the early 20th century. Different names were used by diamond cutters to identify the same shape. However, there are ample evidences to prove that originally the cut was created especially for cutting emerald. Later diamond cutters realized the importance of applying this cut to diamonds as well.

Color and Clarity

The evaluation of color and clarity is necessary. Someone may prefer a warm color of G-H diamond  over a much cooler hue of a D-F diamond. Similarly, while one person doesn’t mind some flaws in the diamond as long as they are invisible, another person would prefer to go for a flawless one.
