Pink Ribbed Optic 8" Vase /Unknown Maker and Age

Sometime I buy pieces because they look interesting or have unusual features or colors. This little vase is an odd tannish pink color and has a very subtle ribbed optic design in it. It's very hard to photograph but shows up well at the top. The body is almost like a soap bubble and the glass is rather thin. The rim is cut but not polished. Judging from the bottom it probably was blown into a mold and then cut off at the top. No marks or labels but I'm thinking Italian because they seem to do a lot of this kind of optic work in their designs. -Mike-
