Mexican Taxco Sterling Turquoise Pendant Pin Brooch

Beautiful vintage Mexican Sterling Silver and Turquoise mosaic pin with 4 mosaic filled drops measures 1 1/2" in diameter. One of the drops is missing as I think it had 5 originally but it is not obvious and does not detract from it at all. It is signed in the back "Tere, Hecho en Taxco, 925 Mexico" and the eagle mark.

Closes with a strong c clasp with safety latch and has a built in hidden bail that will accommodate a chain up to 5mm round.
