Large Rock Candy Emerald Cut Lab-Grown Diamond Eternity Band

$2,250

This lab-grown emerald cut eternity band (18K or 14K gold) offers full/half circle options for tailored luxury. Each 0.25ct lab diamond shines with crisp, geometric brilliance—360° sparkle for full circles, sleek comfort for half circles. Crafted with precision prong settings, it balances everyday elegance and bridal opulence. Ideal for luxury lab diamond wedding rings , stackable emerald cut bands , and versatile occasion wear. IGI-certified, conflict-free. Each stone is a laboratory-grown diamond, chemically, physically and optically identical to a mined diamond, selected for brightness and well-matched colour. The band 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.
