When looking for lab grown diamonds, you might often come across IGI-certified diamonds rather than GIA. Even though GIA certifies lab grown diamonds, the process is still new and you can find only a few GIA-certified synthetic stones.

IGI certification of lab-created diamonds is common and you can use these certificates for evaluating the value of your stones. Similar to a GIA certificate, the IGI diamond certificate will also have a separate grade for each quality parameter including the cut, clarity, and color. The gemological experts will closely analyze each diamond using advanced tools and equipment to find out the grades. Hence, you can use these quality certificates to determine whether the amount you spend on your lab-grown diamonds is worth it.

Lab-Grown Diamond Certification: Things To Watch For

There are some important factors that you should notice when analyzing quality certificates for diamonds. The grading certificates can greatly vary between diamonds and in some cases, diamonds with the same grading reports can have slight variations in their appearance. Hence, when getting a diamond, you have to compare the stone along with the grades given in the reports.

You can also compare diamonds with the same grading reports to find out whether they carry any differences. This can help to find out the best diamonds that can be affordable for you.

When reviewing a grading certificate, you should consider the following factors:

Detailed Grading Is Important

The grading report for your lab-created diamond should have detailed information regarding the quality parameters. The grades given for each attribute like color, clarity, and cut should be noted separately. Additionally, the precise carat weight of the diamond should be included in the certificate.

All these factors are important for determining the price and value of your diamonds.

Diamond Grading Can Be Subjective

Sometimes, there can be slight changes in the grades given for a diamond based on the gemological lab you choose. For example, a diamond that is given a color grade “H” by one lab might be graded as “I” by another lab. This is perfectly acceptable as long as the results are consistent.

Compare Diamonds With The Same Certificates

Diamonds with the same certificates might have slight differences in their brilliance, appearance, and other features. So before choosing diamond rings, make sure to compare them side-by-side to find out the best option for you.

When getting lab-grown diamonds, it is better to ensure that they have IGI, GIA, or other internationally recognized lab certificates. Otherwise, it might not be possible for you to determine the right value of your stones.
