Vintage Silver Tone and Black Marcasite Flower Brooch/ Pin.  It is approximately 2 3/4" wide x 2 1/4" tall.  It is unbranded. 

There is one black Marcasite stone in the middle and 23 smaller stones accenting the entire brooch/ pin.  The Marcasite stones are so gorgeous when the light hits them just right they look dark brown or a deep purple.  The back is textured, or feather brushed.    With it being such neutral colors, it would match anything in your wardrobe.  This would be perfect for Vintage jewelry collectors, Mother's Day, Birthday present, Valentine's Day present, Anniversary present or just an I love you day present.  Condition is used with no bends or missing stones.  Pin mechanism is in working order.  There is no wear that I can see on the silver toned metal.
