Lab-Grown Diamond Certification

Independent IGI, GIA & HRD laboratory verification guaranteeing authentic 4C grading, Type IIa growth confirmation, and laser girdle inscription.

World-Leading Gemological Laboratories

IGI (International Gemological Institute)

The foremost international authority in lab-grown diamond grading. IGI reports provide comprehensive 4C verification (Cut, Color, Clarity, Carat Weight), confirm the synthesis method (HPHT or CVD), state whether post-growth treatments exist, and include digital QR code verification.

GIA (Gemological Institute of America)

The creator of the 4Cs and the world's most recognized gemological authority. GIA laboratory-grown diamond reports evaluate color and clarity using full natural diamond comparison standards, confirming Type IIa crystal purity.

HRD Antwerp

Europe's premier diamond certification authority based in Belgium. HRD certificates are widely preferred by European jewelry houses and luxury retailers for rigorous cut proportion analysis and light reflection diagnostics.

Our 4-Step Quality Control Process

  1. Raw Crystal Selection: Only high-purity carbon seed crystals are cultivated in our HPHT reactors to minimize structural defects and nitrogen impurities.
  2. Precision Cutting & Polishing: Lapidary masters plan each stone with 3D computer scanning to maximize light return, achieve Excellent polish, and ensure optimal symmetry.
  3. Micro Laser Girdle Inscription: Each certified diamond is permanently laser-inscribed on the girdle with the unique laboratory certificate number and "LAB GROWN" identifier.
  4. Dual Internal Gemological Audit: Before dispatch, in-house gemologists examine every stone against the laboratory report to confirm 100% accuracy in weight, dimensions, and inclusions.
