A gentle rose gold wash over sterling silver. The pin measures 3 3/4 inches tall and 2 inches at the widest point. All stones are prong set and secure in original condition. It's a regular bar pin with the locking mechanism at the bottom of the pin as all pins should be. My best guess on this set is either unsigned Hobe or Iskin. The lovely matching screw back earrings measure 7/8 inches across. All 3 leaves on the pin as well as the "knobs" on the earrings are marked sterling. The entire weighs 22.4 grams. I'd put this set between 1930-1950. Again I lay no claim to being an expert on antique and vintage jewelry but I try my best.
