Gorgeous Vintage Native American Tumbled Turquoise and Silver Necklace

This is a beautiful Native American necklace, possibly Navajo. The beads are known as "tumbled" turquoise and have been tumbled utterly smooth. (Except under a jewelry loupe - I was able to confirm minute stone cracks and flaws that helped confirm this is stone. ) This is undoubtedly real turquoise as the color on the end holes is an even darker blue and there is zero white anywhere. . The stones are extremely cold and very heavy. It is strung on wire, which may not be the original cord, but just a guess. Looks like the string broke and someone hand re-strung it on wire, tbh. 10 mm beads, lobster clasp.
The silver components are not magnetic and look to me like sterling.

It's a handmade, vintage, hand strung, old t
