Thank you, DenCil

I know that "made in italy" doesn't reveal anything about the maker or age of a piece but the copper one's shape looked familiar to me so I looked through my books again and I think I found a picture of this exact piece in Leslie Pina's "Fifties Glass" (p.80) attributed to Barbini. I know very little about V.Nason design, though.
The cobalt/turquoise one looks to me to be of the same shape. Do you think it's possible that they were made by the same maker even though the technique is so very different or were lighters/vases of this shape by many companies on Murano?
Day by day I learn a little bit more. It's so much fun to uncover these mysteries and I truly appreciate all the help I get on this board.

'Made in Italy' doesn't necessarily mean it is Murano, of course. The second did look a little like V.Nason, but the aventurine looks too fine and I haven't seen that shape before.
Both are very nice examples though.
