Certification

Certification is a strictly administered process for evaluating and grading diamonds. It is a professional, expert examination to determine the four C’s and further detailed characteristics of a diamond. Diamond certification is written evidence of a diamond’s attributes. When you purchase a diamond with professional certification you are assured of its quality and excellence.

Diamond certificates are issued by independent gemological laboratories. Four of the best laboratories are The Gemological Institute of America (GIA), The American Gem Society Laboratories (AGSL), The Diamond High Council (Hoge Raad voor Diamant/HRD) and The International Gemological Institute (IGI). All four organizations are internationally recognized for their superior professional expertise; therefore certification from AGSL, GIA, HRD or IGI is noteworthy.

Are there different types of certificates and reports?

Each laboratory issues differing reports according to the shape and size of the diamond. Every certificate contains information about the diamond’s characteristics. This includes carat weight, cut, colour and clarity. The certificate is also likely to include information on proportion, cut, polish, girdle, florescence and significant measurements.

Is a certificate really necessary?

Yes-certification is the best resource for an unbiased evaluation of your diamond. It must be from a recognised independent authority.

When buying a diamond always ask for a copy of the certificate or grading report. If this information cannot be given to you then you should seriously consider purchasing your diamond elsewhere.
