Certificate & Authentication

Your Guarantee of Excellence

At Impimo Jewels, we believe in complete transparency and the highest standards of gemstone security. Every Moissanite and Lab-Grown Diamond we produce is a testament to our Bangkok manufacturing heritage and master craftsmanship.

Microscopic Laser Inscription

Every Impimo gemstone above 0.50 carat is meticulously laser-inscribed with a microscopic certificate number on the girdle. This unique identification is invisible to the naked eye but can be verified under 10x magnification (loupe).

This inscription matches your GRA (Global Gemological Research Academy) or IGI (International Gemological Institute) certificate perfectly, ensuring that the stone you receive is the exact one we graded and certified.

Why Certification Matters

  • Verification: Confirm the 4Cs (Carat, Color, Clarity, Cut) of your specific gemstone.
  • Security: The laser inscription acts as a permanent fingerprint for your jewelry.
  • Value: Standardized grading ensures you receive the premium quality you paid for, direct from our factory.
  • Ethical Sourcing: All our Lab-Grown gemstones are conflict-free and environmentally sustainable.

Your certificate is included with every qualifying jewelry purchase from Impimo Jewels.
