About Diamond Nexus

Diamond Nexus is a fine jewelry brand centered on engagement rings and wedding jewelry, set with its own Diamond Nexus stones as well as lab-grown diamonds and gemstones. Shoppers can pick a ring in nearly any shape, from round and oval to pear, marquise and trillion, and in styles such as solitaire, halo, hidden halo, three stone, vintage and bypass, or build their own ring from scratch.

Beyond bridal, the range takes in wedding and eternity bands, matching and stackable bands, ring enhancers, bridal sets, earrings, bracelets, pendants and gold chains, plus a men's line of rings and accessories. The Everyday Radiance collection offers 10K gold rings and bands at a gentler price, and a custom design service lets couples create a one-of-a-kind piece.
