Antique/ Vintage Solid Sterling Silver Brutalist Bib Necklace Unusual Native - Southwestern Gothic Mexico Unique

This necklace is extremely unique, it is old and handmade. It is signed by the maker although I do not recognize it, it is likely either Mexican or American Indian From the looks of it, It is Native of some sort. The necklace is a bib style. Signed Sterling And what appears to be Arano But some of the stamping has worn off so it is possible it says some thing else. Probably mid century modern timeframe. Very unique brutalist style necklace. This weighs approximately 28 grams.
