Harry Iskin 40’s bar pin brooch red rhinestone 1/20 12 KGE

Pretty vintage 40’s Harry Iskin bar pin features a rose gold center flower with a prong set red rhinestone center. 1/20 12KGE. 2 1/4” x 3/4”. Through research, I discovered the designer used this style with several variations. Some oxidation on surface consistent with age. Sturdy pin with roll over closure. Tip of pin extends beyond the closure. This pin has been in my collection for about 30 years.
