Length to Width Ratio
Length to Width Ratio is an important factor in choosing your diamond and is often overlooked. Differing length to width ratios can make a princess cut stone appear rectangular or square and make a marquise shaped stone either appear long and thin or shorter and wider. While ultimately the length to width ratio of a stone is a matter of aesthetic preference, there are a set values that are considered ideal for each of the various fancy shapes. These values are chosen based on the preferred overall characteristics of each fancy shape.
How do I calculate Length to Width Ratio?
Calculating the length to width ratio is fairly simple. Simply divide the measurement (generally in millimeters) of the length of the stone by the width measurement. These measurements will appear in the top left portion of your diamond's grading report. They are listed as length by width by depth. So, if a 1.00 carat princess cut diamond had the measurements 5.86mm x 5.67mm x 3.89mm, you would take the length (5.86mm) and divide it by the width (5.67mm). The depth, while factoring highly into the Cut Grade of the diamond, is not important in finding your length to width ratio. After dividing the two, you get a factor of 1.03. This is your ratio and can be thought of as representing the length of the diamond if the width was represented by 1. This is considered an excellent length to width ratio for a princess cut stone and will appear square.
What is the "Bowtie Effect"?
The "bowtie" of a diamond refers to a dark spot in the shape of a bowtie that is present in fancy shaped stones. This effect is caused by light leaking out of the bottom of the stone rather than being reflected back to the top due to the unique shape of the stone and faceting of the stone. Round stones, with their complete symmetry, do not have a bowtie and therefore do not require a length to width ratio.
