I'M NO EXPERT, BY ANY STRETCH, BUT I DON'T THINK THAT TINY LITTLE LATCH WOULD HOLD UP IF THERE WAS MUCH LEAD IN THE MIX. I'D TAKE IT TO A JEWELER AND GET I PRO TO DECIDE FOR YOU.
JUST A THOUGHT ...

here's the same item for sale online, but with a slightly different charm.

She's asking $32.50 with shipping. On mine, though, the goldplating has worn off in quite a few places, either as a result of the heavy tarnish from the silver damaging the goldplating, or else the silver tarnished where the goldplating had worn off, I'm not sure which. Anyway, I'm satisfied that it's real silver, I think I have a pretty good sense for when something is silver and when its base metal

I found a little ring on the beach Saturday, completely black, I scratched at it with a steel blade and I just got more black. I'd never seen tarnish that thick, I wasn't sure it was possible, and so thought maybe it was a base metal of some sort. Also, the surface seemed rough. My mother was watching and dismissed it as junk. At home, I dropped it in tarn-x for an hour, rubbed it with magic wadding, and poof, there it was "Mex 925" and a hallmark. Also initials on the front plate that I had not been able to read, "SEK". It's a nice, bright little ring now. I just had a sense that it had to be sterling. From the feel, the weight, the form, all added up to sterling, despite its cruddy appearance. I once took an artisan-made sterling bracelet in to a jeweler near my home for his opinion about its provenance, and he wanted $75 before he'd even look at it. I think I need to make friends with a jeweler.
