Is it a champagne flute?
Wrong color but similar shape of the stem.
Libby domaine in juniper green.
Ed: look on the base for a small cursive "L" for verification.
It looks to me like a one-off art piece. I doubt very much that you'll find another just like it. But an artisan glass blower could make you one that's very close.
Probably not worth it unless there is sentimental value involved.
At first glance, I would say it's a soliflore. A vase designed to hold a single stem or flower. But it doesn't look deep, so no clue.
This looks like a decanter.
It's the stem of a wine glass with a shadow underneath because the surface it's on isn't flat
Ahh, silly me.
I don't have a clue where that exact model is from, but you can find good deals on sets of wine glasses at HomeGoods
