Carat is a measurement of weight that is used for diamonds. A 1.00ct diamond weighs 200 milligrams. An easy way
to decipher the weight is to break it up into 100 points per carat (like there are 100 pennies to a dollar). So
a .90ct diamond is 90 points, or a 1.20ct is 1 carat and 20 points. Remember that carat weight does not
determine the apparent size, as this can be altered by other factors of the cut. So not all 1.00ct round
diamonds appear the same.
