This is a lovely pair of vintage sterling silver cufflinks dating to the early part of the 20th Century. The design is transitional from the Edwardian to Deco style. They are oval with a very attractive etched design which includes a cartouche which could be used for initials, but is not engraved. They are stamped Sterling on the back and marked G H C Co. I have not been able to identify this maker.
The surface of the cufflink measures about 3/4 inch by about 1/2 inch. They are in very nice condition.
