You may have heard of diamond grading agencies like GIA and AGS and many have wondered how the grading process is done. If you are trying to know more about the diamond grading process, this post can be useful to you. Grading a diamond is a very complex and intricate process. Anonymity is very much important during the entire diamond grading duration.
Once a diamond arrives at the laboratory for grading, each diamond is put in a transparent storage case. If there are any references accompanying the diamond regarding its owner, it will be immediately concealed or removed. The diamond will then be assigned a barcode that can be used to track the stone during the grading process. Lab-grown diamonds are also graded the same way as natural diamonds.
Why Are Diamonds Graded?
Diamonds are precious stones that have been mined for many centuries. However, without proper grading, the value and quality of these stones are subjective. This is why diamond grades were determined by independent laboratories and jewelers to ensure that diamonds are being judged based on the same grading scale. This will help both the jeweler and the buyer understand what the value of the stone should be.
What Are Various Diamond Grading Factors?
The cut grade of a diamond is based on facet position, symmetry, shine and polish, and many other external properties of the stone. Jewelers will have to spend a large amount of time examining the stones if each of the properties has to be individually graded. But, the cut grade of a diamond combines these properties and evaluates them as a single category. Experts in diamonds and other valuable stones say that this grade should be the chief concern of buyers while shopping for natural or lab-grown diamonds. A diamond that is well-cut, tinted or slightly blemished looks far better than a diamond that is clear, but cut terribly.
The grading scale of GIA measures the 4 C’s of diamond grading, which are color, clarity, cut and carat. The GIA diamond grading scale includes flawless classification and extends to inclusion levels down to “included.” In the “included” diamond grade, the blemishes present in the stone will stand out in the 10X magnification. Depending on the grading level of the stone, the imperfections present in the stone can have an impact on the opaqueness and shine of the diamond.
Why Should You Buy A Graded Diamond?
Though it is not necessary to buy diamonds as per a diamond grading chart, doing so can help save much stress while shopping. GIA grading reports will let you understand if a jeweler is overcharging or offering you a fair price for the stone. Moreover, grading reports will help ensure that the diamond you buy will have resale value if you ever decide to sell it.
