1930’s bakelite napkin rings, just stunning deep green color. Fact! The napkin ring, occasionally called a serviette ring, was originally used to identify the napkins of a household between weekly wash days. Napkin rings are an invention of the European bourgeoisie, first appearing in France about 1800 and soon spreading to all countries in the western world. Most 19th century napkin rings were made of silver or silver plate, but others were made in bone, wood, pearl embroidery, porcelain, glass, and other materials. In the 20th century bakelite and other new materials were used.
