Italian Star Shot Glass
Several of these sold at the Bob Smith tumbler auction in 2019--all of the same design but in different colors; blue, light blue, cranberry (the one shown), light cranberry and yellow. All seemed to have a gold rim and the iridescence stopping about 80 percent of the way up the barrel. I could seen no design element that looked like a star. Each sold for $12.50.

They were listed as late era and having been made in Italy.
