Independent & Transparent Grading
Every CVDLabDiamond piece you purchase possesses an internationally recognized identity report. A diamond's carat, color, clarity, and cut parameters are certified under microscopic laboratory inspections by gemologists, securing your investment globally.
Our lab-grown diamonds are graded using the exact same grading criteria (the 4Cs) as mined diamonds, clearly classified on their certificates as "Lab-Grown" or "Laboratory Grown".
