Fine quality Art Deco platinum and onyx cuff links, made in the 1920s. The square links, with rounded corners and reeded edges, are each centred by a rounded pyramidal onyx, and the links joining them are of the ‘horse-bit’ type which is typically American. They are numbered, but not signed. Each link is approximately 1/2 inch: 12 mm but owing to the height of the central onyx, a fairly large button hole is required. Their gross weight is 16 3/4 grams.
