Stick Pins – Art Nouveau Gold with small Mine Cut Diamond

Vintage Edwardian Early 1900's Stick Pin - filigree box - gold tone, 3.25" long - stick pin/hat pin. It could be older - it has a brassy gold tone metal for the filigree box which is about 3/8" square. It is not signed. It came from a PA estate sale where items were from Victorian times through the 1970's. It has some finish wear and the pin isn't perfectly straight but for 100 years - it's still in good condition.
