What Is Diamond Certification?

Diamond Certification / Diamond grading report is a report that certifies the diamond as genuine and describes it with the information about the color grade, flaw grade, weight, cutting and proportioning etc. Most diamonds above 0.3 CTS are usually evaluated by lab entities. Some of the most reputable Diamond Laboratories are GIA, IGI, and HRD.  As certificates play a main role in determining the value of diamonds, it is important to know more about the different grading systems.

Nishal Gems are sent to a third party laboratory for a comprehensive evaluation; a process known as diamond certification. A reputable lab is one staffed by professional gemologists who specialize in diamond grading. Each diamond certificate issued is uniquely numbered, and corresponds to one individual diamond. From that point forward, the diamond and certificate (laminated to prevent tampering or damage) will travel together from seller to buyer.

Laboratory certification provides an impartial judgment of the characteristics and quality of each diamond. This certification (called a grading report, or dossier by IGI) gives the purchaser added confidence that the diamond received is as described by the seller. The diamond certificate is also valuable for insurance purposes, as it provides a professional, independent evaluation of the diamond.

A laboratory certification is not an appraisal. An appraisal seeks to establish the value of an item, mainly for insurance purposes. A diamond certificate does not evaluate a diamond's market value, only its characteristics and quality. That said, diamond certification from a reputable laboratory is invaluable in generating an accurate appraisal.
