This is a beautiful vintage dress clip. It is brass repousse with large prong set cobalt blue rhinestones. The clip portion is marked PAT 180112?. I believe the last number is missing and the clip dates to the early 1930's. The dress clip measures 2-3/4 inches by 2 inches. The only problem I can find is some minor wear to the backing on a couple of the rhinestones. The clip does have an age patina and may need cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
