Emeralds have shown strong historical price stability and appreciation, with low correlation to traditional markets. GEMx enables institutional investors to access this asset class earlier than ever in the value chain through audited, blockchain-based co-ownership, with built-in transparency, verifiability, and secondary market liquidity. GEMx AG is a Swiss real-world asset (RWA) company that tokenises professionally appraised emeralds. Gemstones are verified by the Gübelin Gem Lab, stored in high-security vaults, and audited monthly by Grant Thornton. Their existence and quantity are proven on-chain via Chainlink’s Proof of Reserve. The EmGEMx token is issued on Avalanche and can be bridged securely to Ethereum using Chainlink CCIP. Supply is governed by the Emerald Standard Unit (ESU) system and anchored to the audited portfolio, making it technically impossible to issue more tokens than emeralds held in custody. Smart contracts audited by Hacken enforce strict controls, including redemption functionality and role-based access. By combining rare gemstones with the power of the blockchain, GEMx offers institutional investors a resilient, physical asset — one that holds its ground even when fiat currencies like the US dollar or traditional stores of value like gold lose reliability in turbulent times.
