Amethyst: Princess of Gemworld Vol.1 #1-12 & Vol.2 #1-16 & Vol.3 #1-4 (1983 - 1988)

Amethyst: Princess of Gemworld is the name of three comic book series published by DC Comics in the 1980s. The series tells of a teenage girl named Amy Winston who discovers that she is in fact the orphaned princess from the magical Gemworld. Amy learns that a evil ruler called Dark Opal is out to destroy her and so travels to Gemworld to overthrow him.
Amethyst first appeared in a teaser story in Legion of Super-Heroes (vol. 2) #298 (April 1983). Her origin began shortly afterward in the twelve-issue Amethyst: Princess of Gemworld limited series in 1983, written and created by Dan Mishkin and Gary Cohn with Ernie Colón as the artist, the initial 12-issue limited series (identified by DC Comics as a "maxi-series") establishes Gemworld, who Amethyst is, and introduces several of her villains that she will face again later. The limited series was followed by a 1984 annual issue and a sixteen-issue ongoing series. The ongoing series was followed by the 1986 Amethyst Special one-shot and a four-issue limited series that ended the character's adventures (pencilled by Esteban Maroto).
