Featured Very unusual ethnic granulated silver and turquoise ornaments

I've had some good luck at the local Savers with silver. They seem to overlook most tribal silver. It was where I've found various Native American silver pieces at costume prices. Today, I picked these beauties there. They remind me a bit of Slavic temporal rings. Of course, with the turquoise inserts, I suppose that's doubtful. I'm thinking Middle Eastern, but there is also a large Native American population near where I live, so they might be Native American... I'd love your thoughts!

 

Lovely, Barn. Not very unusual though, there are quite a lot in this style. They are Central Asian, possibly Turkmen, possibly Uzbek.
Most of these have a hinge, am I missing something?

The ring with a semi-circular decorated part is to be found in many ancient cultures across the world, it is the first step up from the plain ring. It is still found in most continents.

 

Thank you!

Strangely, these don't have a hinge. On one end, the ring is separated from the semi-circle, and there is a hole there. Perhaps the remains of what was once a hinge?

 

I don't think so. Many of these were temple pendants (side of the head, not the building ), rather than earrings. The hole may have been for a thread to keep it in place, so it didn't flip over to one side.
