A striking round vintage brooch from Mexico, featuring a stylized Aztec/Mayan-style face in brushed silver-tone metal, surrounded by a mosaic of natural abalone (mother-of-pearl) shell fragments set against a deep blue enamel background.
Stamped "Hecho en Mexico" on the reverse, indicating handcrafted Mexican alpaca (nickel silver) construction rather than sterling. Fitted with a secure pin-back clasp.
Condition: Vintage piece with natural patina and light surface wear consistent with age; abalone inlay retains its iridescent color play.
