A good quality diamond bear four characters: carat, clarity, color and cut.
February 18, 2006 (Press Release) --
Color: Though most people believe that diamonds are colorless, diamonds, in fact, come in every color of the rainbow. The colored diamonds, known as fancy diamonds, are even more valuable than traditional white diamonds and can be red, pink, blue, green, orange, and brilliant yellow (not to be confused with slightly yellow, which is considered to be a poor quality white diamond).
Fancy diamonds aside, white diamonds are graded on a chart and colorless diamonds are considered the highest quality. The quality ranges from colorless (letters D, E and F), to almost colorless/brown/gray (letters G, H, I and J), to faint yellow (letters K, L and M) all the way to the letter Z, which signifies a light yellow diamond.
Because colorless diamonds are considered the most prized, diamond quality in the higher letters (D, E, F) are the better choice.
Cut: The fourth "C", cut, is the only "C" on which humans have any control. For the other three "C's", carat weight, clarity and color, mother nature deals her hand and we get what she gives us.
Cut can play an important role in diamond quality, because a poorly cut diamond can ruin the value of a stone, and in today's world where profit is the name of the game, master diamond cutters with years of experience are in charge of diamond cutting for any reputable company.
Cut refers to the geometric shape and proportions to which a diamond is pared. In the 1930's a Russian mathematician named Marcel Tolkowsky, derived a formula for which the calculations of the proportions of a diamond's facets (in a round diamond) that would bring an ideal balance between brilliance and dispersion. Since then, his formula is the calculation by which all diamonds are measured.
Though the exact calculation and geometric design are much too complicated to explain, it is important to know that a round cut diamond has 57 or 58 facets (flat planes or surfaces on a diamond that must be cut in exact relation to the others to create the most fire and brilliance). Each facet must be cut an polished to the exact specifications in relation to the other facets on the stone. If facets do not match exactly, the stone it cut poorly the diamond quality decreases.
When looking for a good quality diamond, it is most important to try to find a good balance between all four characteristics. Two diamonds of the same size (carat weight), may vary greatly in value if the other three diamond quality measurements are poor. Remember, don't be fooled by the sparkling diamond and good salesperson at the store - do your research and ask a lot of questions before buying anything.
