Certificate

Certification & Authenticity

Every GemHub & Co. piece is backed by independent certification, so you always know exactly what you're buying.

Our Certifications

• IGI — International Gemological Institute. Independent grading of natural and lab-grown diamonds.
• GIA — Gemological Institute of America. The global benchmark for diamond grading.
• Certificate of Authenticity — Issued for moissanite and selected gemstones, confirming stone type and specifications.

What's on the Certificate

Diamond certificates confirm the 4Cs — Cut, Colour, Clarity, and Carat weight — along with measurements, proportions, and any treatments. The certificate accompanies your piece and is required for any return or exchange.

Verifying Your Certificate

IGI and GIA certificates carry a unique report number you can verify directly on the issuing laboratory's official website. If you'd like help locating or verifying your certificate, email care@gemhub.in.

Please keep your certificate safe — a missing IGI, GIA, or in-house certificate carries a replacement fee, as these are costly to reissue (see our Return & Exchange Policy).
