The Quality of a Diamond: Cut, Colour, Clarity, Carat-weight

This is the size of the diamond measured in carats. One carat is divided into 100 "points", so that a diamond of 75 points weights 0.75 carats. Size is the most obvious factor in determining the value of a diamond. But two diamonds of equal size can have very unequal values, depending on their cut, clarity and colour. And diamonds of high quality can be found in all size ranges.
