This diamond may weigh between 1.75 (7.8MM) and 2.00 carats (8.2MM). The millimeter measurement is the diameter of the girdle, and depending on the cut, this diamond may weigh more or less than indicated, above.
The mm size of a diamond stone relative to its weight in carats is directly related to the cut and the excellence of the cut. For example, a round brilliant stone measuring 8 mm in diameter at the girdle weighs about two carats. A different cut will have a different weight in carats.
Carat weight is a measurement of a diamond or gemstone's weight, not its physical dimensions like length or width. Therefore, the carat weight of an 8mm cushion cut stone cannot be determined without knowing the specific density of the material.
