If the American Gem Society Laboratory were to measure the Brian Gavin Signature Cushion Cut Diamond from edge - to - edge, like
a traditional square cut diamond with pointed corners, the outside diameter measurements would result in an inaccurate representation of the surface area of the diamond.
For instance, the measurements of the 1.662 carat, F - color, VVS - 2 clarity, Brian Gavin Signature Cushion
Cut Diamond used throughout this example, measures 7.91 x 6.62 x 4.83 millimeters, which would result in a length to width ratio of 1.00:1.19 if the measurement represented a
traditional fancy shape diamond, this gives the illusion that this diamond is slightly rectangular, however as you can see from the photographs, this diamond faces up pretty
square.
If the American Gem Society Laboratory (AGSL) elected to measure the Brian Gavin Signature Cushion
Cut Diamond using the same edge - to - edge method which is used for traditional square corner brilliant cut diamonds, such as a princess cut diamond, it would reflect the inner diameter of the diamond only, and thus this would be an incorrect measurement because the outer boundary of the diamond would not be accurately represent
