This is a lovely vintage Art Nouveau sash pin or brooch in gilt brass. It is set with three pink glass stones. The stones are foiled and have some light faceting. The pin is rectangular and it has the smooth organic lines of the Art Nouveau period. It fastens with a C catch. These pins were very popular around the turn of the century.
It measures about 2 1/2 inches by about 1 1/2 inches and it is in very nice condition. There is some light surface wear to the gilt but it is otherwise fine.
