Vintage Mexican sterling silver mosaic brooch pin of inlay of abalone mother of pearl and turquoise with silver outline in a stylized heart motif. The brooch measures about 1 3/4" in diameter and also has a loop on the back to hang a chain, (so can be worn as a pendant also). Marked in back: Mexico 925 Taxco and with initials in the center (which I cannot read). This piece looks to be hand made, and has a loop in back, and also a pin safety clasp.
