Laboratory-Grown Diamonds

AGS Laboratories recently resumed grading laboratory-grown diamonds, a service we previously offered several years ago.

The new enhanced report is the result of over a year of research and development to create a product that helps jewelry buyers better understand the qualities of their laboratory-grown diamonds.

The Laboratory-Grown Diamond Grading Report is in a digital format and is a component of Only My Diamond® (OMD) for Laboratory-Grown Diamonds, which contains additional educational information, including a special section on the 4Cs of laboratory-grown diamonds. Other noteworthy features of the report include:

  • Unique color and clarity grading nomenclature, enhanced educational information, and a focus on precision cutting.
  • The only report of its kind offering AGS Ideal® laboratory-grown diamonds.
  • Two laser inscriptions, which will clearly identify that the diamond is laboratory grown.
  • Growth details regarding the laboratory-grown diamond.

As the market expands, consumers need a diamond grading report that clearly explains the characteristics of laboratory-grown diamonds. AGS Laboratories was founded for consumer protection, and our Laboratory-Grown Diamond Grading Report is one more way that we are demonstrating our commitment to the mission.
