The length-to-width ratio is calculated by dividing the length of the marquise by the width. (Example) Oval length equals 6 millimeters; oval width equals 4 millimeters; 6 millimeters divided by 4 millimeters equals a length-to-width ratio of 1.5 to 1. Diamonds are rarely cut to a perfect 1.5 to 1 ratio.
Note that side 'a' has a length of 25.1, and its opposite angle A is 67Â°. The sine of 67Â° is 0.921, so the ratio of 25.1 to 0.921 is 27.27. If you repeat this for the other three sides, you will find they have the same ratio, designated here by the letter s.
