Mexico Navajo? Sterling Silver/Leather 17mm Ball 17" Collar Choker Necklace 31g

Mexico Navajo? Sterling Silver/Leather 17mm Ball 17" Collar Choker Necklace 31g This is a unique chocker, possibly one of a kind. I was not able to find a similar one in my search. The sterling silver portion slides easily on the leather. The Clasp and one connector are signed 925 Mexico and Ray? My research lead me to an unknown Navajo artist on a page listing Native American Artisan marks. But obviously, is impossible to verify. I have left the patina as an indication of the age but it could easily be cleaned with a polishing cloth. My guess would be 1960's based on the box clasp.
