The Marquise or ‘Boat Shaped’ Diamond
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.
