This piece is probably fashioned from an Imperial Glass #505 goblet. Here is a link with a catalog page which shows this goblet:
It is not marked so was made prior to 1951. It is 5 7/8" h x 4 7/8" w. I think I paid $2.99 for it at GW. It is iridescent, not carnival, but my phone camera filters out the sheen and colors in the finish.
