About emerald cut diamond measurements

These are approximate face-up dimensions for well-cut emerald cut diamonds with standard proportions. Actual size depends on cut depth, girdle thickness, and length-to-width ratio choices.

Always check the specific mm measurements on the grading report before buying. A stone that's technically 1 carat but cut deep will look noticeably smaller than one cut to proper proportions.
