This is a marvelous old hair pin, with a dark patina and accented with chaton-cut rhinestones. I'm not sure what the metal is, and was reluctant to test it even with the scratch method, because I did not want to put any marks on it. It is probably sterling silver, however. The hair pin is 4-3/8 inches long, and 3/4 inch wide at the top. The rhinestones are open at the back, and are all hand prong set. They are in amazingly good shape ("alive") considering the age of this item. Upon request, I will lightly polish the hair pin with a polishing cloth, though in this case I would advise against it. It will be shipped in a gift box.
