Murano? Blenco ? Any ideas?

This is such a beautiful piece but I havent a clue about it? I have comped through my books and scoured the internet and thought maybe this and maybe that? When I purchased it there was two and the were beautiful, a matching set! The boy who was helping at the store was so careless I kept asking him to be careful because I didnt want them to get broken will the first bash just damaged it and the next drop in the bag shattered it to pieces. I think he thought I was over reacting when I asked him to be careful.....boy did he feel stupid and he should have! The people in line behind me let out a synchronized gasp! I was sick about it....then when I got home and washed the remaining piece up I could see a acid etching on the rondil on the bottom, But for the life of me I cannot read it. I think it is a beautiful vase and if anyone could help me with identification it would be great!~Thank you!
