Sarine’s Second Generation AI-Based Diamond Grading
The diamond industry is dramatically evolving from manual to AI-based 4Cs grading. Stay up-to-date and discover the new AI-powered advances.

Brought To You By Sarine
In manual grading, graders have differences in the way they see diamonds and how they interpret what they see. There is also the natural issue of subjectivity when individuals face fatigue and overwork. As a result, the diamond market has always searched for the most accurate and consistent grading service available.

"With the rollout of eGrading™, initially, in the manufacturing segment, Sarine brings AI-based grading to the source, providing multiple benefits and making for a more efficient, shortened, and cost-effective supply chain.”
