Do you know what the symbols on this pendant means?

ok heres my answer! :/ hope it helps. im not as good at american/mexian mythology as greek or irish

in my opinion the "symbols" arent really mayan they are just plain designs to look good,

the man is holding the "Guatemalaian" national symbol (e.g Ireland's is a shamrock) , a bird called a Resplendent Quetzal, thats mentioned quite a bit in South American / mexian mythology which is also called Mesoamerican (aztecs, mayans, etc)

the designs around the edge i thought were serpents were actually still the bird, this shows that it was most likely a Quetzal bird, as they get their name from Quetzalcoatl who was basically a feathered serpent god worshipped by most of these groups.

hope these help, feel free to message me if u need any more help

Those aren't symbols, they're decorative animal, bird and human forms depicted in a contemporary stylized version of native craft. The symbols don't have meaning, they're just decorative designs in order to sell jewelry to tourists.
