This is a very heavy vase. I have no idea what it's made of. There are no markings on it except for 2 stickers. I think one of them shouldn't be on there. One says made in Italy and the other says Sasaki Crystal Handcrafted. I can't find any Sasaki that's made in Italy. Can someone help me identify what this is made of, what kind of glass (or crystal) and anything else.
