Clarity

A diamond’s clarity refers to the absence of inclusions and blemishes. Natural diamonds are the result of carbon exposed to very high heat and pressure deep down in the earth. This process can result in a variety of internal “inclusions’ and external “blemishes” on the stones.  

Evaluating diamond clarity involves determining the number, size and position of the inclusions and blemishes, as well as how they affect the stone's overall appearance. No diamond is perfectly pure, but the fewer the imperfections, the higher the value.  

There are several grades of clarity. At the top of the scale, the “flawless” diamond has no visible inclusions and blemishes. At the bottom, the “included” diamond has obvious inclusions under magnification that may affect the diamond’s brilliance.

Since many inclusions and blemishes are too tiny to be seen by the naked eye, it is important to have a trained diamond professional assess a diamond’s clarity when shopping for a diamond.
