They will then write a thorough description of the diamond’s culet, along with its girdle thickness. The diamond is then set down and picked up with the tweezers in a table-to-culet hold. The first clarity factor which is assessed is a clarity characteristic's size. Perhaps you, like most people, are still unsure of The 4 C’s are cut, clarity, color, and carat weight. Since the late 90’s, they’ve operated as a non-profit organization.

An inclusion under the table and positioned close to a pavilion facet will reflect multiple times around the stone, giving this type of inclusion the name "reflector".

The grader uses darkfield lighting to reveal characteristics, and alternates to reflected, overhead lighting to ascertain whether a characteristic lies within the stone, on the stones surface, or both. The highest and most up to date technology is used for this step. Diamonds with higher clarity grades are more valued, with the exceedingly rare "Flawless" graded diamond fetching the highest price.

Less significant inclusions are ignored for the purposes of setting the grade; however, they may still be plotted onto a diamond plot chart.Accurate clarity grading as with other grading steps must be done with the diamond "loose", i.e. Shopping for the precious gems, however, can be overwhelming. Internal characteristics automatically exclude the diamond from the An internal characteristic of a diamond may be classified as a(n): bruise, cavity, chip, cleavage, cloud, crystal, feather, grain center, indented natural, internal graining, knot, laser drill hole, needle, pinpoint, or twinning wisp.An external characteristic of a diamond may be classified as a(n): abrasion, natural, nick, pit, polish lines, polish mark, scratch, surface graining, or extra facet.The nature will also determine whether an inclusion poses a risk to the stone. The grader views the diamond for the first time through the table, studying the culet area of the stone for inclusions. Therefore, a half-carat stone is 0.5 carats or 50 points. If “pique” meant two different things to two individuals, people might get the wrong impression of what they were buying, and disappointed customers make for bad business. In this position, the diamond can be studied from the pavilion side, and the crown side, examining the diamond through each facet for inclusions. The diamonds must fall into the GIA D-Z color range. This diamond will glisten and be more dazzling than any other step or mixed cut diamonds.While all 4 C’s are important to know in order to compare and contrast diamond value, they are not created equally.

Easy, huh? The AGS 0–10 grading scale is easy to understand: the highest possible grade is zero, and the lowest is 10. These elements can and often do alter the color of the diamond. The decision is then made on the grade of the diamond.The clarity grading system developed by the GIA has been used throughout the industry as well as by other diamond grading agencies including the Clarity grading by WJC standards is by examination using a 10x The American Gem Society grades clarity on a number scale between 0 and 10.
If a GIA report has the words "clarity enhanced" or "fracture filled", it is surely a counterfeit report. The light source and the background can have a major impact on how the color appears. Jewelry speaks its own language, which is understood worldwide.
Such diamonds are sometimes called "GIA, as a matter of policy, does not grade clarity-enhanced diamonds but it will grade laser-drilled diamonds since it considers the enhancement to be permanent in nature. However, large clouds can affect a diamond's ability to transmit and scatter light. The next factor to consider would be the carat size, as heavier diamonds are more valuable. This device dictates their exact measurements, proportions, and all facet angles. Once the entire diamond grading process is finished, the GIA will issue the diamond a certification. Larger characteristics are typically more noticeable under magnification, thereby placing the diamond into a lower clarity grade.The second clarity factor which is assessed is the number of clarity characteristics. Did you know that every single diamond in the GIA is tracked electronically? The most obvious benefit of buying certified diamonds and other gemstones is the insurance that you’re getting what you pay for, and that it is of the utmost quality and beauty. It’s essentially clear, and thus higher in value.
