In 1953, they released their new system which assessed three aspects of diamonds make, color and clarity.

Blemishes Ĭlarity grading Gemological Institute of America grading system History

When diamonds are graded, they are magnified at 10× power. For natural diamonds, the 'internal characteristics' in the diamond are growth crystals that give the diamond its character and unique fingerprint. The diamond industry uses the term 'internal characteristics' instead of 'inclusions'. Features resulting from diamond enhancement procedures, such as laser lines, are also considered inclusions or blemishes. There are several types of inclusions and blemishes, which affect a diamond's clarity to varying degrees. In addition, as synthetic diamond technology improves and distinguishing between natural and synthetic diamonds becomes more difficult, inclusions or blemishes can be used as proof of natural origin. Minor inclusions or blemishes are useful, as they can be used as unique identifying marks analogous to fingerprints. Large cracks close to or breaking the surface may reduce a diamond's resistance to fracture.ĭiamonds with higher clarity grades are more valued, with the exceedingly rare 'Flawless' graded diamond fetching the highest price. However, large clouds can affect a diamond's ability to transmit and scatter light. Most inclusions present in gem-quality diamonds do not affect the diamonds' performance or structural integrity and are not visible to the naked eyes. A clarity grade is assigned based on the overall appearance of the stone under ten times magnification, which is the standard magnification for loupes used in the gem world. The number, size, color, relative location, orientation, and visibility of inclusions can all affect the relative clarity of a diamond. They may be crystals of a foreign material or even another diamond crystal, or may have produced structural imperfections, such as tiny cracks that make a diamond appear whitish or cloudy. Inclusions are solids, liquids, or gases that were trapped in a mineral as it formed. Clarity is one of the four Cs of diamond grading, the others being carat, color, and cut.
