This is a Mexican inlaid turquoise and malachite sterling silver combination brooch or pendant. I believe it is an Aztec or Mayan warrior wearing a headpiece of a bird. In each of the lines on the brooch, there is either inlaid turquoise or malachite. It is hard to see it in my pictures. The brooch is signed 925, TO-27 and Mexico. The brooch measures 1-3/4 inches by 2 inches. It weighs 22.1 grams. It is in very good condition but has an age patina and could use additional polishing. Please let me know if you have any questions. Thanks for stopping by.
