Evelyn’s Three-Ring Lab-Grown Diamond Stack
$1,320
Layer the three silhouettes together or wear them individually for a flexible finished-jewelry look. Confirm ring size and current availability before ordering. The source presents three coordinated rings in one post; they are configured here as separate variations. 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.
