A very smart pair of cuff-links, made in the 1990s in a style reminiscent of the Deco period. Each is set with twelve bright blue French-cut square sapphires semi-invisibly-set with central 'points' a setting pioneered by Cartier and others. They are stamped 750 (18ct white gold) with turn-bar backs - easy to put on.
The heads are approximately 1/2 x 3/8 inches: 12 x 9 mm
