This is our home, our planet, our friends and family! We are the Crystal Gems!
|—Steven Universe, "Reunited"|
Unlike the rest of their kind, they seek to protect Earth instead of exploiting it and are the self-proclaimed guardians of humanity.
Their title distinguishes them from Homeworld Gems, who are their opposites and the ones they fight against.

- Garnet: The level-headed and pragmatic de facto leader of the group and a fusion Gem who wields a pair of gauntlets, later with spiked brass knuckles added. She joined the Crystal Gems after deciding to stay a permanent fusion and meeting Rose Quartz. She is the brawler of the group, using her gauntlets to inflict destructive attacks.
- Ruby: A short-tempered Gem who makes up half of Garnet. She wields a maroon gauntlet. Initially a low-level Homeworld Gem soldier, she was to be destroyed for accidentally fusing with Sapphire, but was saved by her and stranded on Earth. She joined the Crystal Gems after deciding to stay permanently fused as Garnet.
- Sapphire: A calm, yet distant Gem, and the other half of Garnet. Any weapon aside from her future vision has not been seen. Initially a member of Blue Diamond's court, she defected to protect Ruby and joined the Crystal Gems after deciding to stay permanently fused as Garnet.
- Amethyst: The fun-loving and carefree member of the group who wields a one-to-three-tailed whip with morning stars on the end. Unlike the other Crystal Gems (besides Steven and Connie, who are also from Earth), Amethyst was made on Earth, in the Prime Kindergarten.
- Pearl: The intellectual and precise member of the group who wields a spear. She and Rose were the first members of the group.
- Steven Universe: The optimistic and compassionate half-human and youngest member of the group who has healing saliva, and can summon a pink shield and bubble. He is the son of Rose Quartz, (the founder of the Crystal Gems) who gave up her physical form to give birth to him. After growing up in the care of his father, he began living with the Crystal Gems as a member in his adolescence.
- Peridot: The arrogant, curious, and stubborn one of the group. She is a natural-born technician and a certified Kindergartner. She was once an enemy to the Crystal Gems, but was officially accepted into the group after disobeying Yellow Diamond in "Message Received". Due to her natural-born skill in engineering and construction, she is considered to be a technician and engineer of the group like Pearl.
- Bismuth: The boisterous and friendly weaponsmith of the Crystal Gems from the Rebellion era more recently brought to light. Rose showed her she could follow her own wants, but when that included shattering Gems, she and Rose got into a fight, and the latter poofed and bubbled her. She was previously bubbled in the Burning Room due to her battle with Steven over the same issue, but Steven later released her to make amends and invite her back onto the team in "Made of Honor". As stated by herself, her power is equal to Garnet.
- Lapis Lazuli: A laid-back, somewhat deadpan, and easy-going terraforming Gem who presumably served under Blue Diamond, Lapis became Steven's friend in "Mirror Gem" despite having major trust issues and low self-esteem. Starting as an enemy of the Crystal Gems in "Ocean Gem", Lapis later became an ally by warning the group about Peridot and Jasper, then saving them by fusing with the latter into Malachite. Months later the Crystal Gems were reunited with her after Alexandrite split Malachite apart, becoming friends and roommates with Peridot at the Barn in "Barn Mates". In "The New Crystal Gems", she is declared a member of the "Crystal Temps". Lapis later fled Earth in "Raising the Barn" after hearing the word of Blue and Yellow Diamond coming to Earth, only to return and officially become a Crystal Gem in "Reunited".
- Connie Maheswaran: Steven's intelligent and ambitious human friend-turned-girlfriend. Connie took up swordsmanship in "Sworn to the Sword", to join and protect Steven and preserve his legacy. In "Rocknaldo", Steven confirms her place as a member of the group. She also serves as a member of the Crystal Temps.
- Lion: A magical lion that became Steven's pet in "Steven's Lion", but was revealed in "Lion 3: Straight to Video" to have a connection with Rose Quartz, which was explored more in-depth in "Rose's Scabbard".
- Biggs Jasper: A member of the Crystal Gems and one of Bismuth's closest friends. She fought for the Earth, before being corrupted by the Diamonds at the end of the Gem War. Thousands of years later, in her corrupted state, she was forced to join Jasper's "army", but was poofed and bubbled shortly after. She was later healed in "Change Your Mind".
- Snowflake Obsidian: One of the original Crystal Gems. She used to dig ice trenches for Homeworld's armies before defecting and joining the Crystal Gems. However, at the end of the Gem War, she was one of the many corrupted by the Diamonds. She was later healed in "Change Your Mind".
- Crazy Lace Agate: A gentle, carefree Quartz fusion, who defected from Homeworld to join the Crystal Gems. She was corrupted by the Diamonds at the end of the Gem War, but was later uncorrupted in "Change Your Mind" and is currently an employee at Funland.
- Larimar: The cheerful, scream-loving member of the Crystal Gems. She used to be an ice sculptor on Homeworld before defecting and joining the fight for Earth. She, like many other Gems, was corrupted at the end of the Gem War, but was eventually healed in "Change Your Mind".

Afterwards, Steven and the gems support her decision to return to Homeworld and make a fresh start with the Diamonds, and she departs on positive terms.
- Topaz: In "Stuck Together", during Steven and Lars' captivity, Steven manages to befriend the Topaz Fusion to the point where she decides to help them escape.

Over 6,000 Years Ago
Pink Diamond had begged the other Diamonds for a colony of her own until she was finally allowed to have one. Pink chose Earth to be her colony, and like any other Diamond, she sent her Gems to the planet to begin building structures and Kindergartens. The Prime Kindergarten and other structures were successfully established, but Pink soon discovered the life that lived on Earth. She grew fascinated by humans and other lifeforms and knew that if the colony was completed, the Kindergartens would drain all of the life force from the Earth and destroy all life that lived there. Pink attempted to reason with the other Diamonds as to why they could not complete the colony, but when they did not listen, Pink created an alter-ego named Rose Quartz through shape-shifting. Rose Quartz would be used to start a rebellion in an attempt to save the Earth, and nobody would know that it was Pink Diamond behind it all. Pink Diamond (as Rose Quartz) and her Pearl rebelled, founding the Crystal Gems.
Over 5,750 Years Ago
Rose explained to Pearl that by joining her, they could never go home, and if they were caught, they would be killed, which Pearl accepted. At the Ancient Sky Arena, Pearl familiarized herself with the human concept of being a knight and using swords. Later on, Blue Diamond established her court on Earth intending to shatter Rose and Pearl for their rebellion. Ruby and Sapphire assisted Blue Diamond and fought against the rebels, but to save Sapphire from Pearl, Ruby accidentally fused with her, an act that is disgusting to Homeworld Gems. Because of this, Ruby was to be shattered for fusing with the high ranking Sapphire, but the two manage to get away. After spending a lot of time together and developing romantic feelings for each other, Ruby and Sapphire fuse again, and Garnet is accepted into the Crystal Gems. Over time, Rose amassed an army and was able to connect with many Gems who shared her same ideals, such as Bismuth. At the Prime Kindergarten, Rose gave a speech to the other Quartzes, asking if them if what they wanted was to inject Gems and build structures. She also asks if they will destroy the life that's already on Earth or join it. Rose's message got around and resonated with many Gems. Pink Diamond's empathy towards the Earth and beliefs about the Kindergarten's injustice instigated her to defect from her fellow Gems; she truly cared for every form of life on the planet. Another reason that Pink formed the Crystal Gems was that she disagreed with how Homeworld's society ran; she believed that Gems shouldn't have to do what the Diamonds wanted them to do, but instead choose their own lives and fate. When the Crystal Gems began to make themselves known, Pink Diamond told Yellow and Blue at the Moon Base that the colony couldn't be completed because of them, but they still would not listen. Because of this, Pink Diamond decided to wage war against Homeworld to save the Earth.
Over 5,500 Years Ago
The Rebellion officially begins against the Gem Homeworld. Little is known about the ensuing war. Many battles were fought and took place in different locations all over Earth, such as the Ancient Sky Arena, the Cloud Arena, and the Strawberry Battlefield. According to Eyeball, Rose was able to keep her army in contention with Homeworld's superior army because of her healing abilities. Bismuth mentions how she and Garnet took on a battalion of Quartz soldiers together, and how she and Pearl stopped a drop-ship when Pearl threw the Nephrite pilot out of the ship. Bismuth supplied the Crystal Gems with weapons that she created in her forge, and Rose kept most of them in her armory. Around this time, Rose and Bismuth had a fall out due to conflicting ideas, leading Rose to bubble Bismuth and tell the Crystal Gems that she was lost at the "Battle of the Ziggurat". It is believed that humans also fought alongside the Crystal Gems.
Over 5,000 Years Ago
Around this time, Pink Diamond no longer wanted anything to do with Homeworld or her duties as a Diamond. With Pearl, Pink Diamond crushed up dirt and turned it into pink shards. Pink ate the shards and then had Pearl shapeshift into Rose and pretend to shatter her in front of other Gems. From that point on, Pink Diamond was now able to live freely as Rose and Pearl belonged to nobody.
Over 4,500 Years Ago
At this point, Earth is no longer seen as a viable colony to Homeworld. With one final effort to wipe out the Crystal Gems, the Diamonds unleashed the Corrupting Light, corrupting any Gems exposed to the blast. Rose was able to protect herself, Garnet, and Pearl from becoming corrupted with her shield.
The remaining Crystal Gems used their abilities to defend Earth from countless threats. As Rose wished, the Crystal Gems contained the Corrupted Gems in bubbles. Rose made it the Crystal Gems' mission to one day figure out how to cure Corrupted Gems. The Crystal Gems also met and recruited Amethyst, who popped out of the Prime Kindergarten too late to fight in the Rebellion. After falling in love with Greg Universe, Rose, a great admirer of humanity, gave up her physical form to give birth to a half-human child, Steven Universe. The other remaining Crystal Gems (Garnet, Amethyst, and Pearl) have taken it upon themselves to raise him alongside Greg and teach him how to use his powers.
With Homeworld gaining new interest in Earth, Steven and the Crystal Gems continue to protect humanity and contain Corrupted Gems. In "I Am My Mom" and on The Steven Universe Podcast, is shown that the Diamonds know that the Crystal Gems are still active but have decided to just leave them alone and they aren't imagining the Crystal Gems will be an intelligent adversary, as all lifeforms Gems have encountered up to this point weren't difficult to overcome.
In "Reunited", Steven use his mother's aura to reveal to the Diamonds that Pink Diamond wasn't shattered. In "Legs From Here to Homeworld", Steven and the Crystal Gems show the Corrupted Gems to Yellow Diamond and Blue Diamond, and in "Change Your Mind", they show the Corrupted Gems to White Diamond as they thought the rebel Gems were obliterated. They used their power in the water of Steven's mother's fountain to heal all of the Corrupted Gems.
Manifesto of Rose Quartz
"Fight for life on the planet Earth,
Defend all human beings, even the ones that you don't understand,
Believe in love that is out of anyone's control,
And then risk everything for it!"
The Crystal Gems own a section of Beach City's shoreline, on which the Crystal Temple and Steven's Beach House are located. The Barn belongs to Greg and his cousin Andy, but the Gems have effectively taken ownership, using it as a house for new members and to build any required machinery such as The Universe Mach 3 and the Gem Drill. Lapis Lazuli and Peridot formerly lived in the Barn which used to reside on a hill outside of Beach City. In "Raising the Barn", fearing the threat of a diamond attack, Lapis took the barn with her to the moon where it stayed until "Can't Go Back". The barn is currently wreckage on the beach as of "Reunited". Steven and the Crystal Gems temporarily lived in his mother's old room in her palace on the Gem Homeworld, with Pink Diamond's old little friends, the Pebbles.
Lion occasionally acts as a transportation for the Crystal Gems to places they cannot warp to, such as the Moon Base. As of "Bubbled", they owned a Roaming Eye ship that the Rubies left behind, but it was stolen back by Navy in "Room for Ruby". They have also used the Gem Sloop for traveling at sea, though it hasn't been seen since "Cat Fingers". As of "Legs From Here to Homeworld", Steven has gained access to his mother's personal ship and palanquin.
Unbeknownst to all members of the Crystal Gems except Steven, Pearl, Connie, and Lion, the team has access to an Armory containing more Laser Light Cannons and other various weaponry. They also have a Forge which can be used by their blacksmith, Bismuth.
- Instead of stars on their clothing similar to the current Crystal Gems, the Pilot versions have little gold stars pinned to themselves (Garnet's torso, Pearl's earrings, and Amethyst's hair barrette).
- The process for each Gem to summon their weapons depends on a different state of mind for each of them.
- Amethyst places little effort or concentration, claiming that it "just happens" when she needs to summon her weapon.
- Pearl claims her process as being perfect and calculated, using the "dance" of a flower petal in the wind to describe how hard work and dedication can help master the properties of one's own gem and "perform their own dance".
- Garnet claims that she summons her gauntlets by linking her mind with the energy of all existing matter, channeling the collective power of the universe through her gems, matching her calm and meditative temperament.
- Steven's means of summoning his shield rely on his feelings of passion or desire to protect other people/Gems, although in "Gem Glow", the joy associated with eating Cookie Cat ice cream was what summoned it. In both his "Ocean Gem" and "The Return" appearances, he summoned it when it was needed to protect those he loved from a large threat, much like his bubble in "Bubble Buddies".
- All major Crystal Gems, except for Ruby, Sapphire, and Connie (and the formerly corrupted Crystal Gems) have stars located somewhere on their outfits.
- Steven, Steg, and Stevonnie: on his/their T-shirt.
- Garnet: star-shaped visor, stars on her gauntlets and star pattern on her chest.
- Amethyst: on her shorts.
- Pearl: on the back of her jacket and a tilted star pattern above her top.
- Bismuth: tattoo-like marking on her right arm and a red star on the back of her overalls.
- Peridot: on her chest and knees; her visor and hair resemble a star as well.
- Lapis Lazuli: the navy blue portions of her outfit
- Opal: on the draping section of her top.
- Rose Quartz: star-shaped cut out on the torso of her dress, showing her gem.
- Sugilite: black and purple star-shaped patterns on her leggings (like Amethyst) and painted on her nails.
- Alexandrite: special four-pointed star-shaped cutouts on her leggings and star-shaped hair.
- Sardonyx: a black star on the white part of her top.
- Smoky Quartz: on their T-shirt and yo-yo.
- Rainbow Quartz: four-pointed star cutout on her navel.
- Rainbow Quartz 2.0: on their shirt, on the back of their jacket and on their umbrella.
- Sunstone: star-shaped hair and a star on their shirt.
- Obsidian (Steven Fusion): Steven's Star Shirt can be located on their second left hand, and they have a star-shaped marking surrounding Steven's gemstone.
- Although Connie doesn't have a star on her outfit, she does have a star on her new sword as of Change Your Mind.
- Rebecca Sugar also confirmed that the Crystal Gems somewhat represent the ways she acted with her brother Steven Sugar.
- Amethyst is loosely based on Rebecca Sugar's friend Valerie Ang from college.
- Rebecca Sugar confirmed that each of the Crystal Gems is based on one of the stages of the human emotional development spectrum.
- Steven is codependent.
- Common in most children, as children are dependent on their parents or any adult figures on practically anything and everything, as they are expected to be.
- Amethyst is counter dependent; the explorer and rebel, fighting authority and ignoring the consequences of doing so.
- Common in teens and young adults. People here know that they have free will; they usually distrust and challenge their superiors. This is also known as the rebellious stage.
- Pearl is group-dependent; the responsible manager, legalistic to a fault.
- Group-dependent people are ready on taking on responsibilities and expect others to be group-dependent as well. They tend to be obsessed with the notions of obligation and duty.
- Garnet is independent; free to take on the burdens of others can be a bit reckless and is understanding of the growth that risk-taking can give as well as its limitations.
- Tend to be merciful, and kind, and generous. They will help people because they want to, and they will not help people because they do not want to.
- One can also argue that Rose Quartz is transcendent; kind and loving to a fault. She uses everything in her power to help those in need.
- Master of empathy: Understanding in all situations and acts accordingly to the given situation. Merely acts to the best of their ability, understanding the limitations of their own understanding. However, in being emotionally mature, their actions tend to flow out in proper response to most situations, expressing sympathy, anger, and forgiveness when they should.
- Steven is codependent.
- All the Gems' fighting styles are based on different dances: Pearl (ballet), Garnet (waacking), and Amethyst (dancehall and club dancing). This might also have something to do with how they synchronize before fusing.
- The rule that the Crystal Gems won't use their powers on humans was broken in "Keep Beach City Weird" when they attacked Ronaldo, but in that case, an exception was probably made since they were trying to save Steven.
- Each Gem has their own musical palette associated with them, and these respective instruments are used in their leitmotifs.
- Pearl is a piano (secondary: harp, electric piano).
- Garnet is a synth bass (secondary: her synth bell).
- Amethyst is eclectic drums (secondary: electric bass, her synth bell).
- Rose Quartz (as remembered by others) is strings (secondary: piano, her synth bell).
- Steven is a chiptune/triangle wave (secondary: Rose's palette for his Gem powers and empathy; horns for his human physical strength and courage; violin for moments with Connie).
- Connie is a synth bell (secondary: piano for her battle scenes; violin for moments with Steven).
- Peridot is a sine wave (secondary: her bells, her drum kit).
- Lapis Lazuli is a celesta (secondary: timpani, piano, acoustic guitar).
- Bismuth is a reverse electric guitar.
- This can be heard in "Bismuth's Forge".
- In "Story for Steven", before Steven was born, the Crystal Gems were particularly asocial towards the humans of Beach City; on their half of the beach, a metal fence was up to keep humans out of that area.
- Rose Quartz would be a considerable exception to this, as she visited other parts of the beach and saw Greg's concert, but became nervous when he insisted on following her.
- Pearl was confused (not knowing how to make him go away) and mildly bewildered by his presence, simply referring to him as "human" or "it".
- Amethyst asked him various questions.
- Garnet intended to evict him from the temple as soon as she saw him, treating him as an intruder and threatening him with violence (This was put to a halt when Rose Quartz appeared).
- Rose Quartz would be a considerable exception to this, as she visited other parts of the beach and saw Greg's concert, but became nervous when he insisted on following her.
- Peridot has stated that Earth was in the Crystal System, likely where the Crystal Gems derived their name from.
- Except for Steven and Connie, each of the current Crystal Gems are named after a different birthstone.
- According to Bismuth, it was a ritual for the Crystal Gems to spar before the battle.
- The Manifesto of the Crystal Gems was read on the Steven Universe Recap video on Cartoon Network YouTube channel.
- All known Crystal Gems (except for Bismuth and Connie) have demonstrated elemental powers:
- Garnet, as seen in "The Message", has Electrokinesis. She used this ability to power the battery in Greg's Van.
- Pearl, as seen in "Giant Woman", has Psammokinesis. She used this ability to create sand figurines of herself, Amethyst, and Opal, to show Steven how fusion works.
- Rose Quartz, as well as Steven, has Phytokinesis, which allows them to grow sentient flora that does what their creators say, this ability was first demonstrated in "An Indirect Kiss".
- Peridot, as first demonstrated in "Too Short to Ride", has Ferrokinesis, this ability allows her to levitate metallic objects.
- Lapis Lazuli has Hydrokinesis as her main power.
- Amethyst, as seen with her whips, also has Pyrokinesis, as she uses this power as whiplash. This ability has been demonstrated in "On the Run" and "Earthlings".
