AGS Certificate

The Diamond Quality® Certificate is new diamond quality report prepared by the AGS Laboratories exclusively for American Gem Society retail jewelers. It is a Diamond Quality Document plus a guarantee from the participating American Gem Society member store. Essentially, 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 guarantee from a legal perspective. Thus, the Diamond Quality® Certificate is a stronger legal statement from the issuing retailer of the diamond's quality characteristics, including the diamond's cut grade, as well as color, clarity and carat weight.

The Diamond Quality® Certificate is your assurance of a quality diamond backed by a member of the American Gem Society. The Diamond Quality® Certificate is a guarantee - a guarantee of authenticity and quality, certifying the diamond cut grade, color grade, clarity grade, and carat weight of the diamond. Available only through American Gem Society retail members, the Diamond Quality® Certificate was created to further differentiate American Gem Society professionals, while providing you with a greater reassurance in the quality characteristics of the diamond you are considering. Like all of the reports offered through AGS Laboratories, it features a diamond cut grade, providing in-depth information on light performance.

The Diamond Quality® Certificate is authenticated and validated by a diamond professional - either a Registered Jeweler, Certified Gemologist, or Certified Gemologist Appraiser. Their commitment to the tenets of the American Gem Society - Proven Ethics, Knowledge, and Consumer Protection - is your assurance of quality and value.
