Native american Mark with PS and a horse pictorial mark, any ideas ? ( ring)

Appreciate any assistance on ID’ing it/artist

No photo. Just a green box on my computer.

I see it. PS in caps side by side (which are my maiden name initials LOL).

There’s a symbol to the left of the initials, a rectangle with the horse design in it. There also seems to be something above the PS - a C maybe?

I changed save format…should see it now…thanks!

Looks like 925, no luck with the initials though.
