Diamond- Carat Weight

Of the 4Cs, carat weight is the simplest factor used to determine the value of a diamond. As with all precious gems, the weight of a diamond is expressed in carats. One carat equals one-fifth of a gram or 1/142 of an ounce. One carat is divided into 100 points, so a diamond weighing 3/4 carat has 75 points or.75 carats.

As diamonds increase in value, their price per carat usually increases geometrically, not mathematically. Thus, a two-carat diamond will be more than double the price of a one-carat diamond of the same quality.

Diamonds are accurately weighed when they are loose, or free from any mounting. Our diamonds are weighed loose on a calibrated scale.
