Hello,
The bowl appears to be a piece of Murano, Italian glass. Anita may come along and be able to add more. I must say that the use of the canes, and the fact they are not "stretched" in the glass as usual is a little different from any that I can recall seeing before. The circle of aventurine is also a little different.....
It is a nice, and unique looking piece of Murano glass....
