This small pin has an openwork lace pattern on the outside and an oval-shaped turquoise cabochon in the center. There is a distinct matrix pattern in the turquoise. The pin measures 1-1/4" x 1" and is marked on the back "925 Plata." There is also a designer's mark but it is too worn to make out. Looks like it may have a VM in it, but I'm not positive about that. Other than the worn mark, the pin is in excellent vintage condition. (I will finish polishing up the pin before shipping, unless requested otherwise.)
