The 4 C’s
Cut – How a diamond handles light. It is the cut that enables a diamond to make the best use of light. When a diamond is cut to good proportions, light is reflected from one facet to another and then disperses through the top of the stone. The precision with which a diamond is cut is the most critical factor in releasing its “fire” and “brilliance.”
Color – Although most gem-quality diamonds, when seen alone, appear colorless to the untrained eye, there are subtle differences in shade that become apparent to a trained professional. To determine a diamond’s true color, the diamond is viewed from the side under balanced white light. It is compared to diamonds in a “Master Set” whose colors have been predetermined by the Gemological Institute of America (GIA). A color grade is then assigned according to the diamond’s deviation from the truly colorless diamond.
Clarity – Diamond clarity is determined by the absence of inclusions (crystals, feathers, lines, etc.). The fewer the inclusions, the rarer the diamond, and the greater the value. Flawless and internally flawless diamonds are exceedingly rare.
Carat Weight – As with all precious gems, the weight of a diamonds is expressed in carats. One carat equals one-fifth of a gram, or 1/142 of an ounce. One carat is also divided into 100 “points,” so a diamond weighing ¾ carat may be described as weighing 75 points, or .75 carats. As diamonds increase in value, their prices per carat usually increase geometrically, not arithmetically. Thus a two-carat diamond of the same quality will be more than double the price of a one-carat diamond.
