Certification is not to be confused with appraisals. Any jeweler can appraise the diamond using the metrics set forth for the 4Cs and his/her own experience. Certification is a report issued by an accredited independent gemological laboratory after the diamond has been put through extensive scrutiny. Certified Gemologists analyze every aspect (color, clarity, cut, carat weight, dimensions, fluorescence, and all other characteristics) of the diamond under a microscope.
Each gemological laboratory refers to the report with different name:
The Gemological Institute of America (GIA)
– Diamond Grading Report and Diamond Dossier
American Gem Society Laboratories (AGSL)
– Diamond Quality Report or Diamond Quality Document
The European Gemological Laboratory (EGL)
– Diamond Certificate
The International Gemological Institute (IGI)
– Diamond Report
Prime Source Jewelers Diamonds are certified through one of the four recognized laboratories. We not only carry diamonds that are certified we also put them through our quality checks to ensure that there is minimal chance of mistake on the grading of the diamond.
When you purchase certified diamonds from Prime Source Jewelers the original certificate will accompany the diamond. The certificates are needed to insure the diamond or to secure an appraisal certificate.
