At the base of the windmill are two children, a little Dutch boy and a little Dutch girl. The pin measures 2 3/8" x 2". The gold is a rose gold. The piece weighs 22.5 grams. Garman jewelry was made by designer Frank Gargano of Providence Rhode Island in the 1940's. Pieces with this mark are very rare and highly collectable. This is the first piece by this maker that I have ever found. Condition is excellent.
