History Characters / FADIAMTDiamondAuthority

* GallowsHumor: ''Like A Word, A Sound, A Song'' implies Sten has a penchant for this, trying to reassure Greg by sneaking in an IncrediblyLamePun while half-delirious from the effects of a Gem weapon.

* AmbiguousDisorder: A full decade of homelessness and lack of human or Gem contact wasn't kind to his mental health, nor was the brief stint of scientific torture he went through afterwards. When he first ended up in Steven's care he was incredibly stunted both physically and mentally, and was so terrified of humans that the ''idea'' of having to be near one gave him near panic attacks. Even years later he still largely prefers Gem company to human interaction with rare exceptions, and blatantly admits that the fact he doesn't bite anyone who touches him is an accomplishment.

* HundredPercentAdorationRating: Gems (as well as Jets) dearly love their Diamonds to a borderline religious level, a devotion that's only become more severe in Era 3 now that the Diamonds have begun to act more benevolently. [[DiscussedTrope This is discussed more than once as the series goes on]], and it's mentioned that those under the Diamonds' power seem to generate this reverential behavior on their own with no instruction from the Diamonds themselves.

* HumanoidAbomination: On the softer end of the spectrum, but still qualifies, considering the sheer ''scale'' of his powers and the UncannyValley aspects of his physical form. Not to mention his status as a codependent symbiotic [[TheDividual Dividual]].

* HumanoidAbomination: In Connie's own words, Vendan is a ''walking glitch'', and Sten falls well into the UncannyValley with his Gem features.

** They also share alot of mannerisms, body language, and speech in common.

* KnifeNut: Likes collecting and creating knives, and weapons in general. At one point he holed up in his house for a few days and made a literal pile of swords in that short time.

* {{Adorkable}}: Outside of her duties, she proves to be very awkward and nervous, frequently asking the other Diamonds for their opinions on things she becomes anxious about.

* AlternateSelf: He's not a clone of the Steven we see now- he's actually one of ''another'' Asteria Diamond who's timeline now no longer exists, and he's not even the original clone, just another instance of it.

* AFatherToHisMen:

* TheNicknamer: He nickanamed Loki "Locks", and Thor as "little prince", and is apparently the originator of Asteria being "Az."

[[folder: Yellow Diamond]]

A member of the distant Diamond Authority, the creators and rulers of Gemkind.

* GoodCostumeSwitch: Some time before ''Tax Benefits'', the Diamonds made the decision to literally downsize themselves as a way to be more approachable and mutually relatable with Gems.
* HappilyMarried: Steven mentions offhandedly in his AMA that Blue and Yellow Diamond are married. Their behavior in subsequent in-person appearances certainly supports this.
* MamaBear: ImpliedTrope. In ''Diamond Drop'', Steven keeps the events of ''Thor'' under wraps in fear that the Diamond's might react too strongly out of overprotective zeal.
* MonsterProgenitor: The Diamonds are confirmed in ''Aliens Steal Cable'' to be the first Gems in existence, who then went on to create the entire Gem race together.
* StarKilling: While Gems are made from planets, the creation of even a single Diamond requires the absorption of a star.

* TimeAbyss: Considering Steven's mention of Pink Diamond's birth occurring about four gyrs before present (a gyr meaning a billion years), the Diamonds are ''old''.

[[/folder]][[folder: Yellow Diamond]]

Her Luminance, Yellow Diamond, Sword of the Worlds, Song of Penance, Mother of Works, Suneater.

* TheGhost: The Diamonds, while mentioned, don't appear in person until ''For The Tax Benefits, Also I Love You'', the eighth part of the series.
* CoveredWithScars: In ''Prodigal Suns'' it's revealed that her gloves and sleeves cover very extensive lightning scars.

* HappilyMarried: Blue and Yellow Diamond are apparently married, first confirmed in the Asteria Diamond live AMA. Their behavior in subsequent in-person appearances certainly supports this.
* LadyOfWar: Even in times of peace she remains the most obviously military minded of the Diamonds.
* MentorArchetype: Occasionally gives practical encouragement and advise to Az and Connor, especially about uncomfortable subjects and choices.
* SugarAndIcePersonality: Acts formal and professional at all times, even during moments of emotional sincerity.

[[folder: Blue Diamond]]

Her Lustrance, Blue Diamond, Eyes of the Rains, Song of Passion, Mother of Joys, Suneater.

* CoordinatedClothes: Blue and Yellow have the tips of their claws in each other's colors.
* DotingParent: Blue comes across as this, acting like an enthusiastic, supportive mom.
* HappilyMarried: Steven mentions offhandedly in his AMA that Blue and Yellow Diamond are married. Their behavior in subsequent in-person appearances certainly supports this.
* TookALevelInCheerfulness: She's mellowed out considerably by the time of her appearance, being affable, enthusiastic, and encouraging.
* YourMakeupIsRunning: Her eye markings look like tears, and it's later mentioned that she has subtle blue tear tracks going down her neck and around her gem.

[[folder: Asteria Diamond]]

His Radiance, Asteria Diamond, Son of the Rose, Song of Mercy, End of Eras, Suneater.

!!Steven Universe

The "half-human" son of Pink Diamond, the first and only fusion of a Gem and an organic being.

----

** TheDividual: He's a Steven, so he's a fusion- his human and Gem halves are Con and Thorn, respectively.

* JerkWithAHearOfGold: He comes across as surly, impulsive, and even selfish at times thanks to his trauma and mental damage, but at his best he's still a Steven- kind and caring and far too devoted for his own good.

* AlternateSelf: He's not a clone of the Steven we see now- he's actually one of "another" Asteria Diamond who's timeline now no longer exists, and he's not even the original clone, just another instance of it.

* AlwaysSecondPlace: It seems he views Az this way- first in a fearful way, but now in a respectful and admiring fashion. Asteria Diamond, in Connor's mind, is simply ''better'' than him, [[ExperiencedProtagonist both in power and character]]- something Az is aware of and tends to discourage.

* BeserkButton: Anything- places, objects, or people- that he associates with Rose/Pink Diamond or her behavior makes him irrationally angry and uncomfortable. It's something he recognizes and is working on but is still an ongoing problem for him.

* BizzareAlienPsychology: All Gems have this to an extent, but the Diamonds even more so as the "prototype" model of Gems. They're blatantly territorial and possessive, equating things/people they care for as things they ''own''. Of course, they treat their "possessions" with the highest care, but they ''do not'' take it well when their ownership is contested, even by another Diamond.

* 100PercentAdorationRating: Gems (as well as Jets) dearly love their Diamonds to a borderline religious level, a devotion that's only become more severe in Era 3 now that the Diamonds have begun to act more benevolently. [[DiscussedTrope This is discussed more than once as the series goes on]], and it's mentioned that those under the Diamonds' power seem to generate this reverential behavior on their own with no instruction from the Diamonds themselves.
