Anik:
I think your piece could be a relative of Terry's, as I've always thought that Murano was a strong possibility. Terry's has a Camer label on it. Camer was a New York importing company that brought in good quality Murano. I would think Terry's vase would be more likely to be Seguso Vetri D'Arte than A. Seguso,
The neck on your piece is what is unfamiliar to me. There's a a wide variety of shapes and colours to these pieces, and the number of ribs also varies. It looks like yours has 13 whereas others can have more or less. Here are three examples to show variety. The first is a corroso piece by Seguso Vetri D'Arte, the second is also SVdA for Saks Fifth Avenue, and the third a candlestick I know not from whom.
I'd have the piece categorized "Murano (?)" until I found a close relative with a solid attribution.
