Who's mark? 60-70's dangle earrings 925 OAMG? QAMY?

[takoda]

Fab earrings w/ tiny marks on ear wires. Any one know maker? Gotta be 1960-70 hippie design.
I have searched for many days. Is it QAMY?
Any help is appreciated.
I'm quite sure the 925 is before letters due to clear pounded backwards 5 on reverse side as seen on bottom right. I added the upside down image in case someone recognizes that : SHVO???
Where are they from? Who made 'em!?
Pic has both ear wire marks.
