Diamond Certification


Before purchasing a diamond, you should expect to review a copy of its certificate as proof that it has undergone an unbiased, professional examination.

What is a Certification ?

            A diamond certificate, also called a diamond grading report, diamond dossier , or diamond quality document, is a report created by a team of gemologists. The diamond is evaluated, measured, and scrutinized using trained eyes, a jeweler’s loupe, a microscope, and other industry tools. A completed certificate includes an analysis of the diamond’s dimensions, clarity, color, polish, symmetry, and other characteristics. Many round diamonds will also include a cut grade on the report.

CVD Diamond Diamonds are Certified
            Every loose diamond sold by CVD Diamond has been analyzed and graded by either the Gemological Institute of America (GIA) or the American Gem Society Laboratories (AGSL). These two laboratories are among the most respected laboratories in the diamond industry, and are known for their consistency and unbiased diamond grading systems. Diamonds that are accompanied by these grading reports are the most highly valued in the industry.
            In addition to being graded by either the GIA or the AGSL, all CVD Diamond Signature Collection diamonds are certified by GCAL. This additional certification provides a second independent and authoritative analysis of your diamond. GCAL also verifies that your diamond meets all of the demanding quality requirements of the CVD Diamond Signature Collection.

What is the difference between the AGSL and the GIA certificates?
            The Gemological Institute of America (GIA) and the American Gem Society Laboratories (AGSL) are among the most respected laboratories in the diamond industry. Both laboratories are highly respected due to their consistency and their conservative grading standards.
