Onix Negro Los Castillo Taxco Sterling and Black Brooch.
This beautiful face adorned with sterling silver ornamentation measures approximately 1 5/8” by 2 1/4"
Safety catch on pin works beautifully. Some surface scratching and slight damage to the bright finish consistent with age that could probably be polished out by someone who knew how. Personally, I love it the way it is.
Fully marked Onix Negro, Los Castillo Taxco eagle mark, Sterling Made in Mexico, and what appears to be a number 7, which may be the design number. (see photos).
