Napkin rings are an invention of the European bourgeoisie in 1800, originating in France and then spreading to the rest of the Western world.  They were used as placeholder to idetify whose napkin belonged to whom.  In Victorian times, when there was an established weekly wash day, there was a necessity for identifying one's own napkin.  Napkin rings were rarely used by the aristocracy, and only rarely by the upperclasses, as they would have had a fresh clean napkin with each meal.  Napkin rings were often given as christening presents, hence their other, once popular, name, the christening bangle.
