The Diamond Quality^® Certificate is your assurance of a quality diamond backed by a knowledgeable and ethical member of the American Gem Society. The Diamond Quality^® Certificate is a guarantee - a guarantee of authenticity and quality, certifying the diamond cut grade, diamond color grade, diamond 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 our American Gem Society professionals from other jewelers, while providing you, the customer, with a powerful and accountable diamond document.

The Diamond Quality^® Certificate is authenticated, validated and enforced 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.
