Why AGS Laboratories?

Because your diamond deserves the best.

When shopping for something as precious and rare as a natural diamond, it’s important that the diamond includes a diamond grading report from an independent laboratory. A thorough grading report covers all 4Cs—cut, color, clarity, and carat—so that you know and understand the quality of what you are purchasing.  

Most diamond grading laboratories were created as a service to the diamond industry. Not AGS Laboratories. We were founded in 1996 by the American Gem Society (AGS), and are a nonprofit diamond grading laboratory with a mission of consumer protection. This mission ensures you will receive an unbiased opinion on the quality of your diamond. 

This is why it’s essential to have a diamond grading report from AGS Laboratories. It reveals the genuine quality of your precious gemstone, both inside and out. 

AGS Laboratories Diamond Grading Reports feature:

  • Clear and precise grading that is easy to understand
  • First of its kind, patented technology based on science, with grading reports that offer consistency and accuracy
  • Our reports provide six security measures to ensure authenticity
