I can’t tell if this approach originally had a dangle. The bottom looks like it’s possible there was something attached there, but I’m not sure if that’s the case or if it’s just got a slight flaw of extra metal. Still a lovely brooch. Kirks Folly Aurora Pin Brooch is a pre-owned vintage jewelry piece with a diamond shape. The brooch features AB rhinestones. It measures 3 inches x 1 inch.
