Hello, I have been presented this ceiling lamp, blue glass, looks hand-made, but I don't know too much about glass, it's just a guess. height 70cm (28 in.) diameter 28cm (11,2 in.) The seller thinks it's Carlo Nason for Mazzega in the 1960's. After days of research I couldn't find anything even remotely similar. Anyone here has seen any lamp like this before ?
