The GIA developed its scale. There have been pre-existing diamond scale systems like ABC or roman numbered systems. These systems were faulty, making it imperative that the GIA use a unique design to classify diamonds. A brand new, better, and nuanced approach.
The weight value is rounded up if the thousandth of a carat is 9; all other values for the third digit are rounded down. The carat value on a diamond certificate is given to 2 decimal places. On METTLER TOLEDO diamond scales and carat scales, the extra gram scale provides weights to 4 decimal places, offering the next degree of accuracy. This possibility is vital to the cutters attempting to maximize the absolute number of carats they'll achieve from a rough diamond. Additionally, a diamond wholesaler uses many balances and scales, and it's essential to possess consistent performance across all.
