Murano-like Shell Aventurine Bowl

We don't know (for sure) who made this gorgeous bowl, but it has the shape of a well-known Murano (Italy) glass bowl made between 1950 and 1970.  Aventurine glass is made by adding metallic flakes to a deep based colored molten glass.  The results are beautiful. There is one very small imperfection on the inside of the bowl (in pictures).
