This is a beautiful jam set recently acquired from an estate. It is a 4-piece set consisting of a 5 1/2" underplate, a 3" jar, lid and spoon. The jar, lid and underplate are all rimmed in gold. The jar with the lid stands 4". There is very slight wear to the gold trim, but otherwise it is in excellent condition. The pieces are of substantial weight and the jar is hallmarked with a J in a square. The spoon is plastic, maybe even bakelite, but has not been tested. This is a hard-to-find set from Jeanette Glass Company with minor wear.
