Rob Lowe wore one in the form of a cross in 1985’s St. Elmo’s Fire.
In early Soundgarden footage (e.g. 1986), lead singer Chris Cornell sported a longer, more elaborate dangle featuring what looked like coins. Brave. He can wear anything 🙂 So gorgeous. If you’re curious, see minute 1:20-1:55
Peter DeLuise–partner cop to Johnny Depp–wore one in an episode of 21 Jump Street. I think it was the first episode that depicted a car thief also wearing a single dangle earring.
