Gorgeous! Stunning! This lovely vintage brooch is very unique: the sparkly iridescent stones; the size and shape; and, the workmanship.It bears no jeweler's mark, but it is exquisitely made. I'm guessing only, but it seems to be from the 1950s. I bought this at an estate sale approximately 30 years ago. I have used it for display only. You will find it to be in excellent condition.
