Pear shaped dish made in italy

This is a pear shaped dish.  There is

a stem and leaf at the top and a

core at the bottom.  On the backside

there is a mark of what looks to be 

a shield with a crown above it

with the initials G.B.C. Inside the shield..

Below that is listed Made In Italy.

Any help would be greatly appreciated

as I have tried to find who is the maker

of this dish.
