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.
You do not specify if the 8 mm is the circumference, diameter or radius. Please clarify.
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.
