Girls - do you wear "found jewellery"?

This is a bit of an odd one...

I just moved into a new room and I found a tangled up necklace hanging on the mirror. I untangled it and I think it's quite nice. It's kind of like a celtic tangle with a blue teardrop jewel hanging from the bottom - http://www.celticdesirejewellery.com/shop/celtic-n... - it's very similar to that though I expect it's not as valuable.

I am definitely not going to give it to a girl pretending like I bought it - but if, hypothetically, I had a girl at my house and I said: "oh I found this in my room when I moved in; what do you think of it? You can have it if you like it."

Is that weird?

I think it is pretty weird myself - but I'm a boy so what the hell else am I going to do with it? It just seems a shame to have it go unworn.

What is the general attitude towards found jewellery anyway? If you found it yourself would you wear it?
