This fabulous retro brooch by Corocraft is sterling silver with gold vermeil. It is called a stickpin brooch and the colors are wonderful jewel tones of emerald green, sapphire blue and ruby red with diamante accents. The stones are rhinestones and the large ones are open backed and unfoiled. The design is retro dating from the 1940's. This is a large and very impressive piece with some minor wear to the gold vermeil as expected considering the age and use of this brooch. It is about 4 1/2" top to bottom 2 3/4" wide. Please check the photos carefully because it is in excellent condition but not quite perfect.
