Hello and welcome to the board
I've no knowledge on this sort of thing so can't help, but it's a very pretty piece, I thought maybe a claret jug? The star cut base is particularly lovely as well! it looks to have 36 points? I'm not sure if that will be of help dating it perhaps?
Please could we ask that you upload your pictures directly to the board, sizing them to 600 x 400 should work. That way if any information is forthcoming, the pictures are hosted here and remain here for future reference. Otherwise if they are hosted externally, they often disappear leaving the thread devoid of reference and therefore useless to future searches
Hopefully someone will be along shortly who will be able to help more with your id.
Where in the world you bought the item can also help sometimes.
