A properly cut diamond reflects the maximum light back to the eye. Differences between a well-cut stone and a poorly cut stone with the same weight and grade can mean a price difference of hundreds or thousands of dollars.

Diamonds are weighed in metric carats; one carat is equivalent to 200 milligrams. One cart is divided 100 “points,” so that a diamond of 25 points is described as a quarter of a carat or .25 carats. Shown are some examples of the approximate size of diamonds of varying carat weights.

Diamonds are found with a range of colors, from colorless to faint yellow or brown, continuing to pink, blue, green and other colors, known as “fancies.” The differences between one grade and another are subtle, as can be seen by the number of grades within one category. However, slight color differences in diamonds of comparable weight and clarity can make a huge price difference.

Diamond clarity is determined by taking into account the number, size, placement, color and nature of any internal “inclusions” and external “blemishes.” When inclusions do not interfere materially with the passage of light through the stone, they do not affect its beauty. However, the fewer the inclusions, the more valuable the diamond.
