It looks like Murano to me, too, although there is more clear glass in the bottom view than I would expect to see. I'd want to see a clearer picture before confirming one way or the other.
I think Ardy is right about price, but it depends very much where you sell it. The price you would expect to get varies between eBay, flea market, antiques and collectibles fair, and antique store. Country makes a difference, too. I've noticed that different things sell for different prices in Australia, for example, where Ardy lives. If you want an indication of eBay prices, check off completed listing after getting the advanced search of Italian glass, and typing in square geode bowl, or something like that.
