I posted thid over in the Murano forum as well.
I snagged this on Ebay for $2.50. I have a terrible weakness for red and aventurine and this has both. It's not a rare one because I have seen several on ebay. I do know it's italian. I did see a similar weight a while back but I cannot remember for the life of me what the label said.
Does anyone know the maker on the beauty?
