Certificates Diamond Certificates

A diamond certificate, or more accurately called a diamond grading report, is a document created by a team of gemologists that reports the quality evaluation of a diamond.

Diamond grading is a subjective blend of science and opinion. For example, two professionally trained graders can assign the same diamond different color and clarity grades. It is also important to note that all “certificates” are not equal. There are more than a dozen grading labs around the world and all labs have different grading standards. However, while these labs issue these reports, they do not cut or polish the diamonds. Mother Nature determines the quality. Cut is the only quality factor that humans have control over.

At Bailey’s we often buy diamonds without even looking at the report attached because we are GIA-educated gemologists. This means that we know how to grade a diamond and know the correct price regardless of the report. But we also want you to know that we price our diamonds in line with GIA grade pricing. You can be confident that a diamond bought at Bailey’s has the fairest price and is of the highest quality.
