Featured Southwest Style Mixed Metals, Three Translucent "Jewels", Maker's Mark is a Feather

It is 1&1/8 inches square.
Sun moon and stars is the main motif.

Though it is not marked Sterling or 925, I think it is sterling silver that the copper and brass pieces are soldered onto. I did the magnet test, nothing sticks.

The impressed feather is the only mark.

I'm not sure if the "jewels" are glass or stones. The yellow one glows at any angle the light hits it, even if dim. Maybe that's only because it's bigger and has more surface area exposed above the mount and not a specific quality.

The green one also has a pretty good glow but the bluish purple stone has to catch the light just right or it looks flat and dark. All three are translucent enough that I can see dark specks on the metal underneath.

So my main questions are... is generic Southwestern style the best descriptor, or possibly do you think it could be Native American? Or something completely different?

Do you think the stones are glass or something semi-precious?

And of course I am looking for the feather maker's mark.

 

It could not be marked sterling with the brass and copper soldered to it.

 

Well I'll be darned, is that a law?

 

It was before 2018,see paragraph at bottom of page for latest law.

The jewels looks like stones to me (amethyst, peridot & citrine ?), but you will need to test them to be sure.. I don't think it is Southwestern, more like an artisan/studio piece.. it looks like an earring to me ?
It is unique and interesting..

 

Yup, it is an earring. I only have one and I've been thinking of turning the post into a loop so I can make a pendant.

 

I agree the cabochons are the stones Xristina names. At that size, they would not be expensive.

 

I've bought little cabs like that to repair stuff, well under a pound each.
