Diamond Grading Certificate

Why It’s Great

The Diamond Quality® Certificate is a super-powered grading report prepared by the AGS Laboratories exclusively for American Gem Society retail jewelers. It is a Diamond Quality® Document plus a guaranty from the participating American Gem Society member store.

A diamond grading report is an opinion of the laboratory issuing the report. Although the diamond grading report is an expert opinion it is not a guaranty from a legal perspective.

The Diamond Quality® Certificate is an actual legal statement from the issuing AGS retailer, guaranteeing authenticity and quality, as well as certifying the diamond cut grade, color grade, clarity grade, and carat weight of the diamond.

Even better, the Diamond Quality® Certificate is authenticated and validated by an American Gem Society diamond professional — either a Registered Jeweler, Certified Gemologist, or Certified Gemologist Appraiser. It’s all a part of our commitment to ensure your safety when purchasing diamond jewelry.
