Murano Bowl / dish

This is a beautiful Murano Bowl shaped like a shell and ruffled around the edge. It has gold imbedded in the glass along with other designs. I know my sister in law's mother got it in Italy in the 1970's. However, it doesn't have a signature or sticker on it. My sister in law just gave to me because I love Murano and Italian Art Glass.

Because it doesn't have a signature or sticker I would love if someone could verify that it is indeed Murano.
