Request Full Brief →GEMIA WORLD is a London-registered luxury jewellery and fintech platform (Company No. 16632806) operating five integrated product lines: certified fine jewellery (Core), B2B manufacturing as a service (xFACTORY), AI-powered resale liquidity (xVAULT), smart inventory for SMEs (xLEDGER), and open API infrastructure (xAPI). The platform is built on Hyperledger Fabric blockchain and aligned with LBMA, GIA, IGI, and RJC standards.
Each jewellery piece and precious asset in the GEMIA ecosystem is assigned a unique Hyperledger Fabric blockchain record at the point of certification. This immutable record includes mine or refinery origin, GIA/IGI grading data, chain-of-custody timestamps, current ownership and all resale events. The record is tokenised as a transferable digital asset, accessible via xVAULT and the Provenance platform, and surfaced through xAPI for enterprise integrations.
Yes. GEMIA WORLD actively engages institutional investors, family offices, luxury conglomerates, and strategic technology partners. We offer an investor brief covering our five-line platform architecture, addressable market (TAM $340B+ luxury jewellery, $4.2B+ resale), revenue model, team and roadmap. Contact careline@gemia.world or use the investor enquiry button to request the brief under NDA.
xVAULT AI Valuation is priced at £25 per piece. Mobile Valuation is also £25. Marketplace Listing is £45 per listing with an 8% commission applied on successful sale. These are introductory prices — competitive against traditional auction house and jeweller valuation fees of £50–£300+.
xFACTORY serves jewellery brands requiring white-label B2B manufacturing, independent retailers seeking supply-chain access without capital investment, and luxury platforms wanting robotic production workflows. It operates as a dark-factory model: GEMIA manufactures on behalf of client brands, with no end-consumer facing identity. Full NDA and supply-chain confidentiality available.
xAPI provides RESTful and GraphQL endpoints for certified jewellery valuation, provenance data, ownership verification and ESG certification status. Banks can integrate real-time asset valuation for lending and insurance underwriting. Retailers can surface blockchain-verified provenance to consumers. Developers can build on the GEMIA ecosystem via xAPI with enterprise SLAs, sandbox environments and full documentation.
Whether you're an institutional investor exploring the luxury jewellery fintech space, a brand seeking manufacturing access, or a technology platform building on certified jewellery data — GEMIA's five-line platform is your infrastructure.
