Here is an unusual antique American napkin ring. It is not only sterling but inlaid with enamel flowers. This process was difficult to do and not attempted by many silversmiths. This particular napkin ring was made by the Campbell-Metcalf Silver Company of Providence, Rhode Island. The company began operations in 1892 and was out of business in 1898 so the napkin ring was definitely made during that short interval. It is marked sterling and has the company's unusual crown mark on the inside (see last picture). The diameter opening is just under 1,75 inches and the width is 1.25 inches. The ring weighs 1.5 ounces on a postal scale, quite heavy for a sterling napkin ring.
