Amethyst is not primarily defined by carat weight; this is different to most gemstones where the carat weight exponentially increases the value of the stone. The biggest factor in the value of amethyst is the color displayed. The highest grade amethyst (called "Deep Russian") is exceptionally rare and therefore, when one is found, its value is dependent on the demand of collectors. It is, however, still orders of magnitude lower than the highest grade sapphires or rubies (padparadscha sapphire or "pigeon's blood" ruby). Amethyst Amethyst is a violet variety of quartz. The name comes from the Koine Greek ἀμέθυστος "amethystos" from
Amethyst, Princess of Gemworld in the magical plane when Shazam picks up Pandora's Box. It was announced on October 6th, 2018 that Amethyst will appear in the new Young Justice comic to be launched in 2019 as one of its new members. Amethyst possesses a host of powers, including flight, spell-casting, energy manipulation, matter transmutation and can tap other sources of magical energy to amplify her own powers. She is powerful enough to engage in battle with the Spectre and survive. In 2012, DC published an "Amethyst" volume of the "Showcase Presents" series. It reprinted the character’s appearances in "The Legion of Super-Heroes" #298,
