How are Sapphires measured ?
Carat weight is the unit of measurement for all gemstones. It is unit of weight – but not size.
Two sapphires which have the same carat weight may not look the same size depending on the variations in each stone’s proportions, in particular the size of the underside or pavilion of the stone.
Richland Gemstones measures our loose sapphires’ length, width, and depth in millimeters. Trillions are measured from point to point.
