What Certification Means
Certification is an independent evaluation confirming a diamond’s identity, laboratory origin, and 4C grades (Cut, Color, Clarity, and Carat). Lab-grown diamonds share the same optical and physical properties as mined diamonds.

IGI Certificatio
The International Gemological Institute (IGI)
provides comprehensive grading for lab-grown diamonds, including laser inscription and growth method analysis.

GIA Certification
The Gemological Institute of America (GIA)
sets the benchmark for grading standards. Verify your diamond at GIA’s Report Check page.
