The Roberto Coin Diamonds by the Inch collection is built around one simple, brilliant idea — diamonds spaced at perfect intervals along delicate 18kt gold chains, creating a quiet sparkle that catches the light with every movement. The designs are effortless by nature, meant to be worn alone for something understated or layered together for more presence and shine. The collection spans necklaces, bracelets, earrings, and rings, offering a flexible foundation for building a jewelry wardrobe piece by piece. Whether it's your first fine jewelry purchase or the finishing touch in a carefully curated collection, these designs feel just as right with everyday basics as they do with evening wear. Each piece carries the Maison's signature hidden ruby, set discreetly against the skin as a personal symbol of love, protection, and positive energy. Roberto Coin is available exclusively at our Manchester, NH location or online.
