It is hard to tell, but I was judging by the metal holder which appears to be very similar to one I had on my antique uranium opalescent epergne and also the cement used to put the glass in looks to be the same as mine was.
Also each of the baskets appeared to me to have a raspberry prunt on the bottom of them, so I thought English, though I could be mistaken and they might not be raspberries? in which case I would say I thought English if not.
