In GF 2 when Kay tells Mike about the abortion she is wearing a thing around her neck that hangs down between her breasts. I wouldn't call it a necklace, but it is the biggest, gaudiest piece of ..?? It looks like it could be used to signal planes or emit noises.
It was a Sicilian Thing Michael had given to her.
"Io sono stanco, sono imbigliato, and I wan't everyone here to know, there ain't gonna be no trouble from me..Don Corleone..Cicc' a port!"
