Diamond Education: The Marquise Cut Diamond
The Marquise-Cut Diamond is a boat-shaped brilliant stone. The shape of a
marquise diamond can maximize carat weight, giving you a much larger-looking
diamond. The length of the marquise makes fingers appear long and slender.
However, because of the elongated shape, color and clarity imperfections are
more obvious than they are in a traditional Round Brilliant. As with many 'fancy
cut' diamonds you will want to look at the width/length ratio.
Polish and symmetry are two important aspects of the cut. The polish grade
describes the smoothness of the diamond's facets, and the symmetry grade refers
to alignment of the facets. With poor polish, the surface of a facet can be
dulled, and may create blurred or dulled sparkle. It may constantly look like it
needs to be cleaned. With poor symmetry, light can be misdirected as it enters
and exits the diamond.
