18K Lab Grown Diamond Round Solitaire Ring, 1.5 Ct, VVS/E | IGI Certified

A bold 18K solid gold solitaire ring set with a 1.5 ct lab grown diamond in a raised, square-framed top, with two-tone gold panels along the shoulders for a strong, signet-inspired look.

What is a Solitaire Ring?

A solitaire ring centres on one carefully chosen diamond, with nothing competing for attention, so the stone itself does all the talking. Here the diamond sits in a square frame on a broad two-tone band, a substantial, signet-inspired design that suits a man's hand as well as a woman's. Lab grown diamonds are optically, chemically and physically identical to mined diamonds, graded on the same 4Cs, and every centre stone comes with an IGI certificate.

Caring For Your Ring

Clean your ring occasionally with mild soap, warm water and a soft-bristled brush to keep the metal and stones bright — avoid harsh chemical jewellery cleaners. Store it separately in a soft pouch or the compartments of a jewellery box so it doesn't tangle with or scratch other pieces. Keep it away from chlorine, perfume, lotion and hairspray, as these can dull the gold's finish over time. We also recommend a professional check-up once a year to make sure prongs and settings remain secure with everyday wear.
