Vintage Sterling Zuni? Needlepoint Turquoise Pendant and Brooch collection with chain

Product Name: Vintage Sterling Zuni? Needlepoint Turquoise Pendant and Brooch collection with chain
Vintage sterling silver needlepoint turquoise pendant/brooch with chain. It is most likely Zuni Native American but I haven't had it authenticated. The pendant is 3/4" across. Chain is 18". One very small chip on the upper left center stone- see pics. Piece does not appear to be marked, it may have worn away with age. I love making bundles! See collection my other listings for more vintage jewelry and other cool stuff! Items are used and vintage. Some wear and tear is to be expected. Feel free to ask for more pictures before buying. Everything is cleaned in a sonic cleaner with water (except for fabric and natural materials). Metal items are not polished. Please let me know prior to purchase if you'd like me to polish it and I can adjust the price. I use PEEK. Polishing is an additional $5. Thanks for looking! North Shore Aloha Vintage.
