IGI and GIA certifications verify lab-grown diamonds' authenticity, quality via the 4Cs, and traceability, ensuring buyers get real stones-not simulants-with trusted grading. Both are essential for confident purchases in India, where Xazina offers certified pieces for ethical luxury.
What Are Lab Diamonds?
Lab-grown diamonds match natural ones chemically/optically, created via CVD (gas layering on a seed) or HPHT (extreme pressure/heat).
Graded on Cut, Color, Clarity, Carat-certification from IGI/GIA confirms they're genuine, not moissanite or CZ.
They provide sustainable sparkle without mining risks.
