Diamond Shape Diamonds come in a wonderful array of shapes. No one shape is better than another, so choose the shape that you like best.
Cleaving Cleaving involves the removal of impurities or irregularities in the rough diamond. Using a second diamond or a laser, a groove is carved into the diamond along a plane of weakness. A steel blade is placed in the groove and a sharp blow is delivered which splits the stone. Cleaving requires particular skill; if pressure is applied to the wrong area or in the wrong direction, the diamond may shatter. Not all rough diamonds require cleaving or sawing - some diamond rough is well formed and is in ready-to-cut form.
Emerald cut Emerald cuts are sleek and elegant. The Emerald cut is rectangular with cut corners. It is a step cut - its facets being broad with flat planes resembling the steps of a stair. Higher quality Emerald cuts are preferred because its cut makes inclusions and lower color grades more noticeable than with other cuts. Length to width ratio An emerald cut with a length to width ratio of approximately 1.35:1 is generally the most prized. However, in recent years, square emerald cuts have become extremely popular.
Length to width ratio A princess cut with a length to width ratio of less than or equal to 1.05:1 will appear square to the observer. While a squarer diamond is the preference of many, some people prefer a slightly rectangular-shaped princess diamond.
Oval cut The Oval cut is elliptical in shape and is a variation of the round brilliant cut diamond. The oval shaped diamond gives a flattering illusion of length to the finger and hand, and is popular among women with small hands or short fingers. It can also accentuate long, slender fingers. Length to width ratio Length to width ratio An oval cut with a length to width ratio of approximately 1.40 - 1.60 (the average of 1.50 is shown in blue) is the preference of most diamond buyers. For those who prefer a rounder look, choose a ratio closer to 1.15:1. For those who prefer a more elongated shape, look for a ratio of 1.70:1
