Cobalt glass vase

I found this at Goodwill today. At first, I thought it was probably by Indiana Glass Company, but it doesn't match any of the examples that I can find. Also it has a bit more purple in it than most Indiana Glass that I have seen. The shape is also more complex that the Indiana Glass vases in their Illusion line. This vase is 6.25" high x 5.15" diameter at the top x 4.5" diameter in the body x 4" diameter at the base. There is no taper in the body, that is my camera. I couldn't find anything like it in Google, ebay or Etsy images. Does this shape ring a bell for anyone?
