Simons Bros of Philadelphia, PA was started in 1839 by George Washington Simons, at that time, they were manufacturers of gold and silver thimbles and pencil cases. The company grew rapidly from there, expanding to include many gold and silver items including (!) tooth and ear picks, earrings and finger rings. This thimble has a dainty, almost lacey decoration around the bottom, there are no punctures and it is not out of round. There is a hallmark in the top and the words “Sterling Silver”. The number 10 appears on the ring above the decoration on the outside indicating size. There is a patina present which could be removed or left as is.
