Oval Lab Diamond Signet Ring – Bezel Set Minimal Luxury Ring

$1,170

An oval lab diamond signet ring with a smooth bezel setting and solid gold structure. Refined, minimal, and substantial enough to feel special as an everyday fine jewelry piece. Each stone is a laboratory-grown diamond, chemically, physically and optically identical to a mined diamond, selected for brightness and well-matched colour. The ring is handcrafted to order in solid gold by our partner atelier, then hand-polished and inspected before it leaves the workshop. Metal colour, size and stone details can be tailored on request before production. Every Riakoob piece arrives with a certificate of authenticity, insured delivery, and our 12-month value promise.
