As with any valuable and expensive item, it is very important to know exactly know what a diamond is worth. The value of a particular jewel is incredibly important to know, especially in the case that one needed to sell it. Several important factors that affect the diamond valuation; these factors are its cut, its color, its clarity and weight in carats.
A diamond’s cut is just as it sounds: the way that it has been cut to showcase its natural qualities. Some common cuts are princess, round, marquise, oval, pearl, emerald, heart, radiant and Asscher. The best way to determine how precisely a diamond has been cut is to cast a light through it. In determining the color, it is important to remember that diamonds come in many different colors and that the colorless variety is the most valuable kind. The standard measurement system for an uncolored diamond’s color using a letter-based scale in terms of how colored or “uncolored” the stone is.
After simulating day light upon the jewel, a diamond is rated from “D” to “Z”, the scale used for relatively uncolored diamonds, with D being the least colored, closest to clear and Z being the most colored, somewhat close to a shade of yellow. For diamonds considered more colored, however, there is a different scale. Clarity is a measure of the flaws, or lack thereof, in a particular stone. It is determined by using a specified magnifying lens, known as a loupe, under normal light conditions by an experienced grader. If there are no discernable flaws at this level of magnification, a diamond is considered internally flawless.
The lowest grade, known as pique, is determined by the fact that an experienced grader can see a flaw in the diamond without use of a loupe. Carat determines the size and weight of a diamond, and the higher the carat, generally, the more valuable it is. For every carat a diamond measures, it is considered to be the equivalent of two grams (Making two carats four grams, and so on.). It is also important to consider that a large diamond with low quality is not worth nearly as much as a small, flawless diamond.
