Practically, not all diamonds need to be graded in the laboratory. Laboratory reports on small or inexpensive diamonds provide slight benefit to the consumer while adding significantly to the cost. Although having a certified diamond can give you the assurance that the diamond is real, that security can be achieved by dealing with an experienced jeweler or by having an appraisal done by a reputable jewelry professional.

Certified Diamonds are those polished diamonds that have undergone the process of evaluating a diamond quality by a trusted gemological laboratory such as the GIA (Gemological Institute of America) or the AGSL (American Gem Society Laboratories). At the end of the evaluation, a lab report would be issued, which is commonly referred to as “certificate.” The major gemological laboratories act as an independent authority on the identity and quality of diamonds and are not directly involved in the transaction. Non-certified diamonds will always be more common in the marketplace and are merely those diamonds that have not deal with a formal laboratory grading.

Considering the fact that almost any diamond can undergo an evaluation, the mere fact that it is a certified diamond does not certainly mean it is has anything specifically special. The grading information included in the report will just be the evidence of a diamond is classified as gem grade, commercial grade, or a grade below.

Certification is important especially if you are a buyer by reason of providing an independent evaluation of a diamond’s quality. A diamond certificate will make you feel contented and gives a feeling of security of retrieving your money’s worth. On the part of the jeweler, these certificates get rid of the mystery behind the grading of uncertified stones.

On the other hand, if a diamond is non-certified it does not always mean that is of low quality or somehow unappealing. A lot of reasons why a good commercial grade diamond, in spite of its significant size and value, may not be accompanied by a grading report. Diamond dealers and jewelers usually go without the expense of a lab grading report for them to sell the diamond a bit more affordable. It is mostly applied with those common commercial quality diamonds in small to medium sizes. High-quality diamonds in bigger sizes are normally sent to the lab before their availability in the market. Nowadays, customers mostly prefer shopping for a certified diamond, for the reason that you can never be assured of what you are buying if it is without a certificate.

Without a certificate, your only source of information of its quality is the seller, and obviously, the seller’s assessment is probably not going to be fair. The seller may also exaggerate the quality of the non-certified diamond and get overpaid of a stone that can be in a lower price range if it were certified.

The advancement of e-commerce has productively increased the part of the certified diamonds in the current market. It is somewhat difficult today to sell a diamond that is not accompanied by a grading certificate. Likewise, it is also nearly impossible to sell a non-certified through online shops.

To conclude, please be advised that regardless of the diamond type you may be considering, you must only deal with a reputable diamond professional.
