The Crystal Gems

The Crystal Gems, also referred to as the Rebels, are a group of Gems established by Pink Diamond under the guise of Rose Quartz. 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.

Members

 * 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, who is 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 constructing, 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: An apathetic and laid-back 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 off 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 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 and ally. 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.
 * Amber: A former aristocrat who joined the Crystal Gems. She survived the corruption light by being in the Crystal Cove.
 * Iron: A General for the Cyrstal Gems. She invented the geode-bomb and the first blueprints for a gem destabilizer during her time serving White Diamond. She survived the corrupting light by being accidentally bubbled during The Battle of Mask Island, mistaken for a Homeworld Gem.
 * Amazonite: A gem fusion made up of a Rose Quartz who fled being bubbled and fell in love with a Lapis Lazuli. She survived with Amber.
 * Rose Quartz: A singular Quartz saved during an excavation to the Human Zoo when Steven was 5 years old.
 * 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, before being corrupted and bubbled. She was later healed in "Change Your Mind".
 * Snowflake Obsidian: One of the original Crystal Gems, before being corrupted in the Gem War. She was later healed in "Change Your Mind".
 * Crazy Lace Agate: A Quartz fusion who was temporarily corrupted by the Diamonds. She was later uncorrupted and is now an employee at Funland.

They build the furniture all night to remind the Crystal Gems like the one back on Earth in "Together Alone".
 * Yellow Diamond: After learning the truth about Rose being Pink Diamond, she, along with Blue Diamond and Steven, attempt to heal Nephrite.

However, their relationship would sour during the Era 3 ball in "Together Alone": Yellow Diamond is infuriated with Steven after he fuses with Connie, locking him into a prison tower after poofing the other Crystal Gems. As of "Change Your Mind", however, she seems to have made peace with them.

Additionally, she is willing to help the Crystal Gems return to Earth after being convinced that Pink Diamond is happier there.

Afterward, 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. Before they can, however, Aquamarine catches them and reminds the fusion of the consequences of betraying the Diamonds: her two halves would be separated and shattered. Realizing her error, Topaz resumes her mission to deliver Steven and Lars to Homeworld. In "Little Homeschool", she is seen in a sort of meditation class with Garnet and many other gems.

She gets caught up in the moment and accuses the Diamonds, getting poofed by Yellow Diamond as a result.
