Hi Kittiesgalore and welcome to the board

Your vase is beautiful! The ones you have linked to do have similarities. Unfortunately I don't know anything about this type of glass so can't help further, but I'm sure someone will be along soon who should be able to help. Just give it a little time as not everyone visits the board everyday

I don't know about the base finish of your vase, with the polished pontil mark, I'm not sure that is something that is associated with Murano glass, which I think would often have a flat polished base. But as I say, it's not my collecting area so my knowledge is very limited. I'm sure someone will be able to help you soon. Keep checking back to see if there have been any replies.
And thanks for the lovely photos.
