The decanter looks to have the Seguso scalloped label, at least the remnants of it. I really like the color on it. Looks like an excellent piece!
The lighter could be a Cenedese piece. I had a similar one in yellow with a rectangular Murano label, attributed to Cenedese.
And Laura, where did all those come from?

I really like the yelow one, and the one next to it in a golden color. Really nice!
