Gugunava Jewelry is a London-based fine jewellery studio by Arsen Gugunava — maker, stone setter and teacher with 15+ years across three continents. Every ring designed, set and finished by one pair of hands. Natural and lab-grown diamonds, spinel, sapphire, ruby, emerald and all fine gemstones — ethically sourced and traceable. Bespoke commissions and stone setting courses in London. By appointment only.
