At the time once more observing the require for a universal process, the GIA produced the diamond color grading scale, utilizing the letters D-Z, which is most widely acknowledged right now. Diamond are graded under extremely precise viewing situations and usually in comparison to diamond of a recognized coloration grade to ensure quite few discrepancies in just a colour quality. A diamond absent of color is quality ‘D’ and the a lot more coloration that is existing in the diamond, the even more along the alphabet it can be quality travels.

Blemishes are external flaws found on the surface area of a diamond, and include things like chips, nicks, and scratches, most of which take place all through the cutting process. Inclusions are inner flaws these types of as bubbles, cracks, or other minerals inside of the center of the diamond.
GIA made a common diamond clarity grading scale consisting of 11 grades. Diamond are graded less than 10x magnification, so most of the flaws that affect the clarity grade are scarcely noticeable to the naked eye. In addition to the quantity, dimension, and severity of the inclusions, the situation and coloration of the the inclusion are also viewed as when grading the clarity of a diamond. Since no two diamond are alike, the attributes of a diamond and it’s inclusions make it solely distinctive, and are often used, like fingerprints, to establish particular person diamond.
The most rare clarity grades are F or FL (flawless) and IF (internally flawless), diamond of these grades are much much more precious since they do not manifest as normally in character. The next finest clarity grades are VVS (pretty, really slightly included) and VS (pretty a little incorporated). These diamond are additional popular and sought immediately after due to the fact they are extra reasonably priced than flawless diamond nonetheless still have pretty small inclusions, most of which can only be witnessed under magnification by a expert grader.
