Solid Stone. Elements of earthy stones that range from muted to dazzling. Choose from cufflinks in round button styles, square styles and abstract gemstone settings for formal or daytime business looks. Black onyx cufflinks accent any formalwear or crisp white cuff. Mother-of-pearl cufflinks create a more muted experience. Signature stones such as abalone, blue lapis, tiger's eye and sodalite create unique visuals that transform suited up looks.
