I was about to post that this could be Villeroy & Boch, based on the fact that I had one in green and one in red. They were supposed to be used for tea-lights, although I ended up selling mine. Howeverrrrr...after looking at the photos harder, I think the glass of yours is thinner and possibly finer and older than mine was, although the silhouette and pattern is very similar indeed. Also...it looks like yours has a kind of 'hump' in the bottom? The V&B ones don't have that as far as I can remember.
I looked all over Google, on here and on ebay and couldn't find any tea-light holders the same as the one I had, sorry. :cry:
