Can anyone tell me what these “pieces” are called....

Hi everyone....
I have a box full of these insects and flowers; they’re made of metal—partly copper and partly tin-plated.... I think they’re used as decorative elements for Tiffany-style work...
But I can’t find the name anywhere, not even online. I even have some that are still in their original packaging. Maybe someone knows what “something like this” is worth....
Best, Stephanie 

Stephanie, try searching on Google for “metal
butterfly jewelry”
and then click on “Images.”

You’ll see quite a few results, and you’ll be amazed at what’s out there. I’m sure some of them will even list the value.

Your pieces look very pretty. Otherwise, I’d ask a jeweler.

Stephanie, try searching for “Tiffany” instead of “jewelry”—you’ll find quite a few more results, and the prices are already pretty high. From what I’ve seen, over 100 euros.

Thanks, Monika, for your reply....
I just spoke directly with a dealer; apparently, these were “mass-produced” and are no longer being made. As for their value, he just said they’re worth nothing.
   I still think they’re kind of “cute”... I have no idea what to do with them, so I’ll put them up for sale and see what happens. 🙈
But first, a few particularly beautiful pieces are moving into my room. For example, there’s a really great pair of elf wings and one or two insects.... 

Yes, Steffi, your pieces are really very pretty... You’re sure to find grateful buyers who’ll be delighted with them. Elf wings... that’s something special.
