No, it isn't Dino Martens. A rumor was started a few years back that Dino Martens designed this type of glass for AVeM. The rumor was repeated in a couple of books, then soon was considered to be true. I wrote Marc Heiremans, an authority on Martens, 2-3 years ago to ask if any of the tutti-frutti pieces had been made by Martens. He said no.
After looking at the blue underside of your bowl, I am not certain that it is Murano glass. The base doesn't look polished and the circles are not something I would expect for Murano. I'd like to read other people's thoughts on this.
