Lab Grown Diamond Certifications: What Do GIA, IGI, and GCAL Approve?

More Than Just Sparkle — Trust Matters

The quality of a diamond extends beyond its brilliance because certification stands as equally vital. A certified diamond gets its quality and characteristics verified by independent third parties. The grading process for natural and lab grown diamonds follows the same standards which gemological institutes around the world use to verify their quality.

GIA – Gemological Institute of America

The Gemological Institute of America stands as the leading authority when it comes to diamond grading. The organization produced certificates exclusively for natural diamonds throughout several decades. The GIA introduced specialized reports for lab grown diamonds in 2020 which brought about a significant transformation to the market.

The GIA provides a complete evaluation of Color Cut Clarity and Carat in their reports for lab grown diamonds.

Each report carries a distinct report number which users can check through the online system.

The worldwide acceptance of GIA certificates establishes trust during your purchase.
