Wow, thanks for all the help! I wouldn't say lime green, it is a little darker than the picture, but very close. I'm pretty sure they are vintage, but you never know of course.
I got them from an estate that had several high priced and high quality collectibles, the people were most definitely very well off. I wish I could have afforded some of their other stuff! Though I think these were still a bargain, a lot of people in my area are clueless about Murano glass. But I am no expert either, but I have some knowledge which I am building on.
While I am here I might as well ask, does anyone know a good website that describes the different terms for different Murano techniques?
Thanks again for the wonderful help, it is really apreciated!
