Why Choose an IGI Certified Lab Grown Diamond Engagement Ring?
Independently Graded
Every diamond graded by IGI for cut, color, clarity, and carat weight. Certificate included with every ring — verifiable at igi.org. The same grading standard applied to natural diamonds.
Chemically Identical to Mined
Lab grown diamonds share the same chemical composition (pure carbon), hardness (10 Mohs), refractive index, and optical properties as natural diamonds. Not simulants — real diamonds.
50–70% Less Than Natural
The same budget that buys a 1.00ct natural diamond buys a 2.00ct+ lab grown diamond of equal or better cut, color, and clarity. Larger presence, same certified quality.
No Mining Required
Grown via CVD in a controlled environment. No earth disruption, no conflict supply chains, fully traceable from creation to certification. The responsible choice without compromise.
