This is a vintage Mexican silver wire work bee / bug pin.  It is marked "made in Mexico", has the old C style clasp, and measures 2" x 1 1/2".  It is tarnished but otherwise good shape with the possible exception that there looks to be some sort of tiny appendage on one side that I don't see on the other so is maybe? missing something there but displays fine.  Always happy to combine - check out my other auctions.
