Kara Yellow Oval Diamond Ring
$3,870
The piece is presented in 18K yellow gold with lab-grown diamonds. The design is intended to be worn as rings and styled as a refined everyday or occasion 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.
