Certification
Certification in the jewellery trade refers to the formal validation of materials, processes, and expertise—from gemstone grading reports and precious metal fineness marks to professional qualifications and ethical supply-chain endorsements. These credentials matter to UK jewellery professionals for establishing trust, ensuring compliance, and supporting premium pricing. Jewellery Focus delivers in-depth coverage of certification in all its forms, including lab reports (GIA, IGI), UK hallmarking, Fairtrade/Fairmined and sustainability seals, accreditations from Gem‑A and other bodies, plus courier and security compliance standards. We explore how certification shapes sourcing decisions, retail disclosure obligations, consumer confidence, and regulatory audits—helping retailers, designers, gem dealers, manufacturers, and valuers understand pathways to accreditation and leverage trust-enhancing credentials in the UK market.
