Marquise Cut Diamonds

Marquise-cut diamonds

The marquise-cut diamond is a stunning, timeless choice for engagement rings and other fine jewellery. Its long, elegant shape is similar to that of an oval-cut diamond but with pointed ends. The marquise-cut diamond is also known as the "navette" cut, which is French for "little boat."

This cut was popularised during the 18th century by King Louis XV of France, who commissioned a jeweller to create a diamond cut in the shape of his mistress's lips. The marquise-cut diamond has since become a classic engagement ring choice and is also beautiful in other types of jewellery.

When shopping for a marquise-cut diamond, it is crucial to keep in mind the "bow-tie" effect. This is when the diamond appears to have a dark area in the centre, in the shape of a bow tie. This is caused by an optical illusion and is not a defect in the diamond. Marquise-cut diamonds are often used as centre stones in engagement rings and other jewellery pieces because of their brilliant sparkle and elegant appearance.

When shopping for a marquise-cut diamond, it is essential to pay attention to the quality of the cut. The cut of a marquise-cut diamond affects its symmetry, brightness, fire, and overall sparkle. A well-cut marquise-cut diamond will have excellent symmetry and be very bright and full of fire but will cost much more.

The length-to-width ratio of a marquise-cut diamond is also important to consider. This ratio is used to determine the ideal proportions of a marquise-cut diamond. The length-to-width ratio of a well-proportioned marquise-cut diamond should be between 1.75 and 2.25.

When choosing a marquise-cut diamond, it is also essential to pay attention to the quality of the diamond's clarity. Marquise-cut diamonds are often cut to maximise their brilliance, which can sometimes result in a sacrifice of clarity. However, there are still many beautiful marquise-cut diamonds available with excellent clarity and for a great price.
