This pendant is just marked Made in Mexico, and I have not had it tested, but I am sure it is Vintage Silver. The Black onyx face has a bezel set rope surround, and then a row of small silver balls on the outside of this. The brooch is 2 1/8 inches long, and 1 1/2 inches wide. There is a safety lock on the clasp. It is marked on the back Made In Mexico.
