Part of Serge De Nimes’ Hidden City Collection, the Onyx Armour ring takes inspiration from the overlooked details woven throughout London’s streets and architecture. A black onyx stone sits within a square signet face, while the textured oxidised surface echoes the raw materials and patterns found across the capital, bringing together natural contrast and architectural influence. 925 Sterling Silver Oxidised Finish Engraved Branding Style Code: S-OXAR-RNG
