This is a stunning pectoral known as "The Turquoise Mosaics," created by the Aztec or Mixtec culture around 1400 to 1521. What you're looking at is a pectoral in the shape of a double-headed serpent, a form with deep symbolic meaning.
The serpent is carved from a single piece of cedarwood and covered in turquoise mosaic, a material highly prized in Mesoamerica. Tiny, polished turquoise pieces are carefully arranged to mimic the scale pattern of the snake. The open mouths display fangs made of conch shell, with red oyster shell used for the gums and nostrils. Tiny black and red bands add a dramatic touch around the snouts.
The double-headed design may symbolize the celestial realm and was likely connected with power and ritual. Small holes at the top suggest it could be worn across the chest as a pectoral, perhaps during important ceremonies.
