This is a Trifari piece. I have looked up the Design patent as "Patent #130136 Date: Oct. 28, 1941 Item: Pin Clip Owner: Trifari, Krussman & Fishel Inc. Inventor: Philippe, Alfred" If you can live with beauty and not perfection this is for you. I say this because there is loss of enamel on this which is not noticeable when you wear it. Also, it has had the pin replaced at one time.. All that aside, this is a fine piece of jewelry. It is a leaf motif with green glass oval stones and white rhinestones and black enamel. It measures 2 1/2 inches long and 1 3/4 inches wide. It's weighty. Marked with "Des. Pat. No. 130136" Also marked with a 'P'. Truly a work of art. The patent number puts this piece circa 1941. I love it.
