Created by writers Dan Mishkin, Gary Cohn and artist Ernie Colón, she debuted in The Legion of Superheroes #298 in April 1983.

After the events of Flashpoint, the character was retroactively rebooted, having first been raised by her mother Graciel to help eventually liberate Gemworld from a tyrannical ruler.

Amethyst's premise was initially pitched to DC Comics under the title "Changeling", wherein its main character had been left on Earth as an infant.

[2] This in turn inspired the jewel-themed renaming of the other characters in the series and the rebranding of the entire concept as "Gemworld".

[4] Her original story 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, Amethyst's identity, and several of her recurring villains.

[20] Amethyst appeared in the 1997 "Convergence" crossover that ran through Book of Fate, Night Force, Challengers of the Unknown and Scare Tactics.

After Dark Opal kills Amethyst's parents, the witch Citrina sends her to Earth to be raised by the Winston family.

The Amethyst miniseries sees the characters' return from their fates and takes place two decades after Crisis on Infinite Earths.

[24][25][26] Amethyst possesses a myriad of powers, including flight, spellcasting, energy manipulation, energy constructs, eldritch blasts, matter transmutation, magic resistance, atmokinesis, chronokinesis, chlorokinesis, elemental control, life creation, reality alteration, crystal enchantments, crystal generation, conjuration, summoning, size alteration, divination, hypnotism, emotion manipulation, telepathy, telekinesis, teleportation, dimensional travel, invisibility, illusion casting, invoking spirits, necromancy, healing others, and hyperawareness, as well as the ability to tap into other mystical sources so she can amplify her own capabilities to near-incalculable levels.
