Marquise Diamond Guide

Please see the ideal table, depth and length to width ratio combinations for marquise cuts. An important consideration when selecting a marquise cut is the colour. Marquise tend to show colour more than round diamonds because they have less depth in the tips. When considering other factors, be sure that the diamond looks symmetrical. The two pointed ends should align with each other. If possible opt for a diamond with excellent or very good symmetry. In terms of clarity, avoid a diamond that has visible inclusions in the central portion.
