What an ordeal. But the Diamonds needed me. That's the burden of being the best.
|—"I Am My Mom"|
Aquamarine is a Homeworld Gem and antagonist whose shadow was first seen in "Doug Out". She made her official debut in "Are You My Dad?". She was sent to Earth with a Topaz fusion to retrieve humans for Yellow and Blue Diamond to take them to Pink Diamond's Zoo.
Aquamarine is a small Gem, only about half of Steven's height. She has a cherubic appearance and a bright cyan-blue complexion, navy blue eyes, no nose, and chin-length, cerulean-blue hair worn in a bobbed style. Her clothing vaguely resembles a prep school uniform, consisting of a blue vest worn over a dark blue dress with a white collar, white wrist-length gloves, white knee-high socks, dark blue flat shoes, and a dark blue hair bow that she can turn into her wand. The intersection of her vest and the lapels of her collar form a Blue Diamond symbol, hinting towards her superior. Her teardrop-shaped gemstone is located beneath her left eye, and her water wings are similar to a butterfly's wings. Her outfit, wings and the use of her stasis wand give her the appearance of a fairy or pixie.
Aquamarine is particularly small, particularly young, particularly important...

Like many Homeworld Gems, Aquamarine has an arrogant streak, frequently believing that she is better than everyone else--going so far as to call herself "the best". This results in her having a short temper when things do not go as she planned, quickly getting annoyed with Jamie for "ruining [her] moment", followed by Topaz prolonging the battle in her ship. She is shown to be manipulative, using negative reinforcement against the Crystal Gems to comply with her demands and convincing Topaz to release her by warning of future retribution from the Diamonds. She is also spiteful, seen when she mocks Steven clearly for her own amusement in "Stuck Together".
Like Blue Diamond, she follows Homeworld's dogma to the letter, warning Topaz in her fusion not to commit taboo and break down into a sentimental state. Despite all of this, she has been shown to have at least some capacity for pity, as she is willing to overlook Topaz's defiance and sudden burst of aggression in exchange for loyalty and pretend that nothing has happened.
Aquamarine and Topaz are sent to Earth personally by Yellow Diamond to retrieve the humans Steven mentioned in his first interaction with Peridot in "Marble Madness" for Pink Diamond's Zoo. Aquamarine has mistaken the humans Steven mentioned for "varieties" of human rather than specific individuals.
Aquamarine and Topaz chase down Onion at Beach City Funland during the middle of the night. When Doug Maheswaran calls out to them, Aquamarine drops a fence on him. Once Doug, Steven, and Connie leave the scene, Aquamarine and Topaz approach Onion and capture him.
Aquamarine and Topaz capture Jamie when he is out to deliver the khakis Steven ordered. Later on, at Funland Arcade, Aquamarine approaches Steven and asks him if he is "My Dad". Upon realizing that he is not, Aquamarine flies away in disappointment. Steven and Connie later find Aquamarine in a forest, where Aquamarine asks Connie if she is "My Dad".
When Steven mentions Connie's name, Aquamarine becomes excited and calls out for Topaz, telling her that she "found one". Once Topaz captures Connie, Aquamarine tells her not to bother with Steven since he is not "My Dad". Aquamarine then summons her wand, paralyzes Steven, and launches him toward a tree. Aquamarine and Topaz leave the scene to hunt down their last human, leaving Steven unconscious.
Aquamarine and Topaz hide in Funland, but Steven and the Crystal Gems eventually find them. Aquamarine points out how strange it is that Steven knew everyone on their list, but concluded that the list did come from "a Steven". Aquamarine tells the Crystal Gems that she will leave the Crystal Gems alone if they tell her where she can find "My Dad". Steven is confused by this, causing Aquamarine to explain that Yellow Diamond asked for "My Dad, a Connie, a Lars, a Sadie, a Mailman, and an Onion-I-Think", as specified in a report by Peridot.
When the Crystal Gems go to attack the duo, Aquamarine effortlessly uses her wand to throw the opposing members about. At some point, Aquamarine gets annoyed by the fighting and threatens to kill each of the humans if the Crystal Gems do not tell her where "My Dad" is. When Steven tells her that he is "My Dad", Aquamarine questions how "a Steven" can also be "My Dad", but believes it regardless out of impatience concerning the completion of her mission. Aquamarine activates her ship and taunts the Crystal Gems with the captured humans and Steven.
On the ship, Aquamarine prepares to set a course for Homeworld. She becomes furious when Steven manages to free everyone from Topaz and orders the Topazes to stop them from escaping. When Steven finds a way out and everyone jumps in the water, Aquamarine uses her wand to paralyze everyone. Steven reveals himself to be Rose Quartz and offers up himself to be taken away instead of his friends. Aquamarine accepts the compromise, as Rose Quartz is potentially a much bigger prize in the eyes of the Diamonds. She and Topaz take Steven onto their ship alone and fly away, setting course for Homeworld.
On her ship, Topaz finds Lars still aboard. Aquamarine is delighted to find that they get to bring back at least one of the requested humans in addition to "Rose Quartz". Steven objects to this and demands they release Lars, but Aquamarine disregards him.
While heading for Homeworld, an issue occurs with the engine, and Aquamarine orders Topaz to fix it. After wondering why Topaz was taking so long in the basement of the ship, Aquamarine discovers that she had planned to help Lars and Steven escape. Topaz retaliates and attempts to use a Gem Destabilizer on Aquamarine, but Aquamarine talks Topaz down by reminding Topaz that she would be separated and shattered for her defiance. Finally arriving at their destination, Aquamarine tells Topaz that she will pretend nothing happened.
Several Aquamarines can be seen cheering the return of Pink Diamond (as Steven).
Aquamarine possesses standard Gem abilities.
- Water Wings: Similar to Lapis Lazuli, Aquamarine can summon water wings on her back to fly or evade enemies during combat. They have a noticeably sharper shape than Lapis' water wings, shaped like butterfly or pixie wings.
- Keen Memory: Aquamarine appears to have very good memory, being able to remember the names of six humans without any lists, descriptions, or visual aid. In "I Am My Mom" she remembered that the Diamonds didn't specify "alive" as a requirement for the humans. It's shown in the same episode that she takes great pride in this ability, calling her memory "perfect".
- Wand: Aquamarine wears a navy blue ribbon on her head which she can whip into a small wand.
Look, just... unfuse, and we'll never speak of this again.
Aquamarine is superior in rank compared to Topaz, and as such, Topaz obeys her orders without hesitation and does not object or argue despite having dissenting opinions. After being opposed and attacked by Topaz, Aquamarine shows mercy and decides to pretend the ordeal never occurred.
According to Pearl, Aquamarine was sent personally by Blue Diamond (and Topaz by Yellow), indicating not only that she is of a very high rank, but that she is a highly trusted member of Blue Diamond's court. Although she expresses disdain towards her mission on Earth, Aquamarine is very intent on getting what the Diamonds have requested.
Oh no. Is Rosie upset 'cause her widdle deal didn't work? Look, I'm so moved, I'm crying. Just kidding. That's my gem!
Steven initially had thought that Aquamarine is a Gem with no ill intent, until he realized that she was on Earth to collect more humans for the Zoo, specifically, Steven's friends. Aquamarine, just like most other Homeworld Gems, thinks Steven is Rose Quartz. Therefore, she shows distaste towards him, mocking him for her own amusement.

- Aquamarine is the smallest non-corrupted Gem shown so far.
- Aquamarine loosely resembles Cirno from the Touhou game series.
- Aquamarine's butterfly wings are the third time butterflies have been shown in a negative context. The first being when butterflies attacked Steven in "Serious Steven" and the second being the "anxiety butterflies" in "Mindful Education".
- Aquamarine's appearance and personality along with her wand give her the impression of an evil fairy or pixie.
- Though her gem looks like a teardrop in many shots, her facial expressions make it look like a sweat drop, an anime trope that denotes exasperation or embarassment from characters.
- A tattoo of a teardrop in real life means that the wearer has murdered someone, attempted murder or is seeking revenge for the murder of the wearer's loved one. It also represents "ever-flowing tears", signifying that the wearer is mourning someone.
- When asked why she paired Aquamarine and Topaz together, Rebecca Sugar said it was to show both sides of the very high-ranking types of Blue and Yellow Gems on Homeworld.
- Along with Sapphire, Jasper, Padparadscha and the Rutile Twins, she appears to lack a nose.
- According to an episode of the Steven Universe Podcast, she is based off of Eric Cartman from South Park.
|Aquamarine's gemstone is located on her left cheek; the shape resembles a teardrop. It also appears to be a cabochon, a gem that has been polished but not faceted.|
