The 4 Cs of Diamonds
Clarity | Diamond clarity is affected by the existence of inclusions and blemishes on a diamond. Inclusions are those internal characteristics that include crystals, clouds and feathers, while blemishes are surface irregularities. An inclusion may be foreign matter or another diamond crystal. While most inclusions will not affect a diamond's fundamental structure, tiny imperfections may appear whitish or cloudy. Clouds can affect a diamond's ability to reflect light. Cracks near the surface may weaken a diamond's resistance to fracture. Minor blemishes and inclusions may be useful in identifying natural diamonds. often acting as nature's fingerprint. As synthetic diamond technology becomes more and more advanced, it may be hard to determine whether a diamond's origin is natural or synthetic. However, inclusions and blemishes can serve as proof to its natural origin.
Cut | When it comes to the four Cs, cut is the most important since it determines a diamond's symmetry, proportions and facets. While many believe it is the weight of a diamond that matters most, it is the cut of a diamond that affects its brilliance, sparkle and durability. Since a diamonds' cut affects the overall quality, diamond cutters often consider shape and size when deciding on a cut. The three most important parts of a diamond are the table, crown and pavilion. The table is the measurement across the top of a diamond. The crown is the height of the top portion of the diamond from the girdle (where the pavilion and crown meet). The pavilion is the depth of the diamond from the bottom portion of the stone. The measurements in the table, crown and pavilion affect not only its sparkle, but how flaws are displayed.
Carat | Carat refers to the weight of the diamond. One carat is the equivalent of 0.2 grams. A carat is divided into 100 points. A 50-point diamond weight 0.50 carats.
