No assay mark or artist's signature. An older piece, I think. Aztec head brooch with bale. Clasp works fine. Clasp a bit loose.
Stones have very slight flaking.
No other marks. Good, heavy weight. Good condition overall with slight dents at bases as shown. Slightly wonky bottoms prevent them from resting completely flat. Azteca eagle motif pin with yellow, red-orange, green, and black inlaid feathers.
