Vintage Mexican Sterling Silver Green Stone Aztec/Mayan Face Ring 5mm Band Sz7.5

-This is a vintage Mexican sterling silver ring featuring a carved green stone centerpiece in the form of an Aztec or Mayan-style face mask. The ring is marked "Mexico Sterling" inside the band, confirming its silver content and origin. - The face is set in a wide, 5mm band with a decorative beaded border around the bezel, typical of mid-20th-century Mexican artisan jewelry. The green stone is likely either dyed agate, chrysoprase, or possibly malachite, though this cannot be confirmed without further testing. - The ring is in overall good vintage condition, with some expected patina and surface wear on the silver, and no visible cracks or chips to the stone.
