YOUR CERTIFIED DIAMOND

Why American Gem Society (AGS) Laboratories?

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 4Cscut, 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


Each DIAMONDS IN SPACE diamond will come with an AGS Laboratories Diamond Grading Report.

Accept no substitutes, and buy your diamond with confidence!
