The marquise diamond has a distinguished past in the world of aristocracy; it first made an appearance at the behest of a king to express his love for his mistress and to argue that the grace and form of her lips deserved to be captured in a diamond. How lovely! Given that it is long, narrow, and has pointed ends, the marquise diamond is the perfect shape for making your finger appear slimmer and more slender. This diamond’s long body gives it the appearance of being larger than it actually is; it makes it appear as though it has an equal carat weight to a round diamond, which has a greater carat weight.
