An example would be on large emerald cut diamond which has small inclusion under the table and positioned close to pavilion facet, will reflect multiple times around the stone, giving this type of inclusion the name reflector. Reputable vendors must disclose this filling and reputable filling companies use filling agents which show flash of color, commonly orange or pink, when viewed closely. For this reason reflectors have greater impact on the clarity grade.

Diamond clarity is quality of diamonds relating to the existence and visual appearance of internal characteristics of diamond called inclusions, and surface defects called blemishes. An inclusion under the corner of the table.

There is significant price discount for fracturefilled diamonds. Only about 20 of all diamonds mined have clarity rating high enough for the diamond to be considered appropriate for use as gemstone the other 80 are relegated to industrial use. The GIA will not grade fracturefilled diamonds, in part because the treatment is not as permanent as the diamond itself. The VS category is divided into two grades SI1 denotes higher clarity grade than SI2. In they released their new system which assessed three aspects of diamonds make, color and clarity.

An inclusion under the corner of the table. Slightly Included category SI diamonds have noticeable inclusions that are difficult to somewhat easy for trained grader to see when viewed under 10x magnification.

These inclusions often be more easily seen from the pavilion side, and the crown side, examining the diamond through each facet for inclusions. The number, size, color, relative location, orientation, and visibility of inclusions can all affect the relative clarity of diamond. They took terminology used in the industry at the time and refined the definitions to produce clarity scale by which diamonds could consistently be graded. The grader views the diamond for the first time through the table, studying the culet area of the stone for inclusions.

But GIAs passion, integrity, and commitment to research remain the same. GIA has also developed software that provides method of estimating cut grade and database that is embedded into number of leading diamond measuring devices so that this estimation can be automated. In the 1950s, GIA created the International Diamond Grading System, and established the standards that revolutionized the diamond industry. Our research has shown that many different proportions can produce attractive diamonds.

GIAs mission of ensuring the public trust in gems and jewelry is reflected in this international research undertaking. As result, manufacturers can plan and, in effect, predict cut grades, buyers can compare cut qualities, and retailers can communicate the effects of cut on round brilliant diamonds. After more than years of research and discovery, GIA has developed scientific way to assess and predict the cut quality in round brilliant cut diamonds. Sincerely, Thomas When think back to that era of innovation, it is truly aweinspiring.
