AGSL History

Established in 1978, AGSL is a non-profit organization dedicated to promoting consumer protection and the advancement of gemological education. They use a rigorous certification process that evaluates each diamond’s authenticity and quality based on the “4 Cs” – cut, color, clarity, and carat weight.

We believe that the cut of the diamond is one of the most important factors in determining its overall beauty. AGSL’s experts evaluate the cut based on several factors, including proportions, symmetry, and the diamond’s ability to reflect light. This ensures that our diamonds have maximum brilliance and fire, making them stand out from the crowd.

AGSL also evaluates the color of each diamond using a standardized lighting environment to determine the exact color grade. This ensures that our diamonds have the most desirable color, adding to their overall beauty and value. Shop certified diamond engagement rings
