The marquise cut diamond has one of the largest crown surface areas of any diamond shape, making a 3 carat marquise appear significantly larger than a round or cushion of the same weight. Originally commissioned by King Louis XV of France to resemble the lips of his mistress, the marquise remains one of the most romantic and striking diamond cuts in fine jewellery. IGI certified by Inasha Diamonds — real, ethical, and hallmark certified.
