Marquise Cut Diamond

A diamond cut that can make you stand out for its sheer exquisiteness is marquise. Just like the shape of an ellipse or a football, the marquise cut diamond is elongated, has curved shape and two pointed ends. The elongated shape flatter a wearer’s finger making it appear longer and slimmer. In addition, they can make the diamond size appear bigger. Marquise cut diamonds are blessed with one of the largest crown surface areas, which also combines to give a notion of greater size. The shape complements a solitaire setting and even a side setting. The unique shape will surely demand the attention of the people around.

The marquise cut diamond of length to width ratio of 1.75-2.15 is widely considered the most ideal and classic marquise cut. However, individuals may have their own preference and may wish to go for a narrower or a fatter version.Generally, excellent or very good symmetry is highly recommended because even a slight non-alignment at the two end points will give it an offbeat look when finally set.This will ruin the overall look of the jewelry. Since the two pointed ends are nearer to the brink of the rough stone, flaws and inclusions might be hoarded there. Covering the pointed ends with prongs will conceal the flaws present while also rendering the stone the support needed in a setting. It is to be noted that the pointed edges are very much prone to chipping.

Marquise cut diamonds have varying degree of bow-tie effect that ranges from near indistinguishable to severe. A bow-tie is basically a dark area in the center of the stone that usually occurs when the light is not allowed to bounce back in the middle. It is only via physical inspection that the severity of the bow-tie effect can be ascertained as no diamond certificate or dimensions can show you the result.

History of Marquise Cut Diamond

Its history dates back to the 18th century. The most widely accepted story centers around the legend of the French King Louis XV who ordered his court jeweler to produce a diamond in the shape that resembles the smile of his mistress Jean Antoinetter Poisson, the Marquise de Pompadour. The term marquise has links with the heredity rank between a duke and an earl, exemplifying the fact that there may be a certain degree of genuineness in the legend.
