A Leader in Industry Firsts
Since our founding in 1996, the AGS Laboratories has achieved many industry firsts and accomplishments by pursuing our mission statement. Among our highlights, we:
- Pioneered the Ideal Cut Grade for the Round Brilliant diamond. (You may also hear it called the AGS Ideal or the Triple Zero Cut.)
- Created the first scientifically reviewed, objective, and repeatable Cut Grade method in the industry — still the only of its kind.
- Became the first major lab to offer diamond grading reports with a Cut Grade for fancy shapes, including Princess, Emerald, and Oval, as well as patented proprietary cuts.
- Offer diamond grading reports that have a simple, straightforward, and intuitive scale and provide all the information you need to be comfortable in your diamond-buying decision.
- Provide a variety of diamond grading reports, both with and without a diamond Cut Grade, to suit the specific needs of diamond manufacturers, retail jewelers, and of course, you, the consumer.
