Murano glass vase

I believe this is Murano Sommerso. No label. I have had it for about 20 years. It belonged to my Mother. I am in the process of selling it. One problem is that one guy had one similar and had it listed as antique and another one similar listed as vintage. I sort of go with vintage. Both listings ended so I have no idea of the value either. It is 15" tall and 7 1/2 wide at the top. Neither one listed were exactly the same. I don't know what this is called but the lines on their vases were straight up and down. Mine is a waved pattern. Thank you so much for any help.

 

Japanese, rather than Italian, I suspect.

 

Thank you.

 

Oh, this is the one that was listed as Antique Murano Sommerso. I forgot to put it up with mine.

 

It isn't sommerso, it's graduated. Sommerso is sumberged: one colour inside another. I don't think that seller was being accurate.
