Carat Weight And Size
How are sapphires measured?
Gemstones vary in density, so a sapphire and a diamond of the same carat weight are visually different sizes. Because sapphires tend to be heavier, a one carat sapphire is generally slightly smaller in size than a one carat diamond For ease of selection and setting, size is a more useful measurement, which we list in millimeters. Our standard size for a round sapphire is 6 mm, which is approximately one carat.
Brilliant Earth carries a variety of shapes and sizes beyond our standard so if you are looking for something more unique, please contact us.

Sapphires are generally measured by size rather than carat weight.
