Cufflinks in onyx and platinum. An etching process has given the onyx pieces their distinctive surface of fine fissures and textures – at first glance it looks like a mosaic of several small stones, but each onyx is in fact a single, continuous stone. This keeps the cufflinks compact and sturdy despite their intricate appearance. Hammered platinum settings, held by likewise forged platinum rings, carry a half-sphere on one side and, opposite it, a lens-shaped stone that slides easily through the buttonhole. For men who want to do without ordinary polished cufflinks.
