Vintage Swank Gold Tone Square Faux Pearl Cufflinks Geometric Mid Century

I have a vintage pair of Swank cufflinks here with square gold-tone fronts and small faux pearl accents. I like the curved raised design against the flat square background—it gives them a nice mid-century look without being too flashy. They are marked Swank on the backs. Each measures about 23 mm across, and the pair weighs about 20 grams.  These have square fronts, raised curved detailing with a faux pearl on each cufflink, and traditional swivel backs.  These do show their age, with scratches, scuffs, some discoloration, and wear to the finish. The flat backs have quite a bit of surface scratching. I don't see any missing parts, and the swivel backs are intact. Please look through the photos closely for condition.
