ANTIQUE FAUX PEARL & BLUE & RED CABOCHON HAT PIN

Victorian like hat stick pin has a lovely brass open work filigree head with a faux pearl cabochon. Under it an oval shape blue cabochon stone and the bottom stopper has a ruby cabochon stone. All of this in a very old brass setting. It has a hallmark on the back of a cross inside of a circle. I am not able to identify this mark. The piece measures approx. 5.75" on a 4.75" pin shaft and measures, in total 5.75" long and is 1" wide. Condition is excellent. Great addition to any collection. As with all my listings of jewelry it is being offered with free shipping in the U.S.A. only. Insurance is extra. See all my many other great listings.
