The Crystal Alliance is the name given to the group of planets ruled over by the Next Gen Crystal Gems in the future.


The Crystal Alliance was formed after the 3rd War, each gem colony divided among the main 9 members of the Next Gen Crystal Gems. It is currently peaceful and had found ways of artificially implanting gems into the children of half gems if they wish to have them, though it is compulsory in the noble and royal families for children to become half gems. Though many of the planets have a similar history of being gem-colonies, the moon was quite different.

It was a peaceful gem civilization with history going back predating the diamonds' conquest. Founded by Queen Celenia (Celenia the Light), it interacted with earth the gems on the moon procreated with humans and for a while the Kingdom was bountiful with wealth and peace until the diamonds drew close. Years rolled by Queens Yue (Yue the Lonely), Artemis (Artemis of the Arrow), Crescent (Crescent the Glorious), Chaandanee (Chandanee the Goddess), Maanblom (Maanblom the Fairest) Bulan (Bulan the Avatar), Yoru (Yoru the Enchantress) and Silver (Silver of the Spindle) held back many adversaries from Homeworld. Until the reign of Queen Shadow (Shadow the Traitor) whom sold her own Kingdom to the diamonds, for a Sunstone that wooed her. White Diamond and Shadow attacked but were defeated by Luna's mother Queen Rainbow (Rainbow the Undefeated). Eventually the Kingdom fell and was taken over by Pink Diamond. Only to be revived 6000 years later by Luna.
