delicate little gold ladies ring (setting, anyway?)

This might be the mostest-bestest tiny little prize from the 'house cleanout in progress'...mebbe even the most 'valuable'...? :-)

Found buried in the very back corner of a kitchen drawer full of mostly rusty tools and old household hardware (along with copious amounts of, shall we say, "infestation evidence" of numerous kinda things that can infest such places <eeek><ugggh>) while otherwise digging around with a screwdriver saving errant (corroded) pennies. WHOOPS, I says to myself -- that's a *whole* different little glint of shiny there <wow> and *right* into my pocket it went...?!! ;-) ;-) ;-) :-) :-) :-)

After getting it home and looking closer, plus a gentle cleaning with warm water and a toothbrush (which brightened it up even more) it appears to be at least the setting of a ladies gold ring. **VERY** difficult to photograph, I hope y'all can at least get an idea of it. I would imagine there was once a very small diamond (?) in its center between the four tiny 'posts' on its raised (hollow) center feature, the detail on that and its surrounding parts of the band on either side of it is quite delicate and very intricate, also hollow inside. The rest of its band is quite thin (and indeed somewhat bent and out-of-round) and if there are any markings on it (or any other part of it for that matter) I haven't been able to discover/discern them yet. It weighs 2 grams.

And that's really all I know about it, except that it also happens to fit on my pinky finger. I suppose I should take it to a local jeweler or three to try to find out what it really is/isn't...in the meantime if anybody recognizes anything at all about it in some way, please share the clue!! :-) :-) :-)
