Her Rings A two-piece stack in solid 925 sterling silver with a blackened black-ruthenium finish, centered on a coffin-cut simulated emerald (approx. 2 ct) framed by simulated diamond (CZ) accents, with a matching shadow band. His Ring A comfort-fit, domed black tungsten carbide band inlaid with crushed green fire opal—rugged, scratch-resistant, and quietly luminous. Coffin-cut emerald & green fire opal Her center is a coffin-cut simulated emerald—an elongated casket silhouette hand-set for a rich, saturated green, the storied color of the May birthstone. Emerald has symbolized love and rebirth for millennia; our emerald and May birthstone guide traces the lore. His band answers it with crushed green fire opal, so the pair reads as one deep-green story across two hands. Metals & everyday wear Her rings are solid 925 sterling silver finished in black ruthenium—a rare platinum-family metal—for a deep gunmetal, blackened-silver glow; his is black tungsten carbide, one of the hardest, most scratch-resistant metals in fine jewelry, with a comfort-fit interior. Both are hypoallergenic and nickel-free, and her rings can be upgraded to solid gold on request. You'll find more pairings in our gemstone couples rings.
