I am still with John in believing this
is Murano (and AVeM)
>> Here is a comment by Anita *TxSilver* on a (admittedly nicer) Tutti Frutti toothpick holder; it has the same shape, the same unpolished base -- and what seems to be a worn AVeM label.
As I said, I have yet to see a Chinese piece with zanfirico inclusions. The ones brucebanner linked to on alibaba are quite abundant here on the fleamarkets and on ebay, but IMHO don't have much in common with the piece in question.
And especially the pink, yellow and blue twisted canes lined with copper aventurine are quite distinctive, and found in almost any of the AVeM pieces.
The white and blue lining is unusual, but on Wayne's site is another one with a white background
>> Link (second row from the bottom).
And I have an ashtray as well with a white background.
(BTW, the big vase was my biggest disappointment yet, as it arrived smashed to 100 pieces due to bad packing.

I glued it back together just to see what it would have looked like...)
