The Gems all have a different magical weapons that they summon through their gems. Since the Gems are their true selves, the weapons naturally reflect their user.
- Garnet has a pair of gauntlets that are projected out of the gems embedded in her hands, representing her as The Stoic, hands-on leader of the Crystal Gems.
- Amethyst, the fun-loving party animal, uses a whip to wildly thrash around on any opponent.
- Pearl, the elegant but neurotic Lady of War, gets a spear and has a collection of swords in her room. She treats combat as a discipline and has several tools for the sake of practice and teaching.
- The titular character Steven, a Friend to All Living Things, has a shield that he inherited from his equally-loving mother. His mother also used a sword that is not projected out of a gem, but is instead summoned out of Lion, representing her willingness to fight for those she wants to protect.
- Peridot's "limb enhancers" aren't her Gem weapon, but they're her main, and seemingly only, offensive weapon. With them, she can Wall Run, use a Tractor Beam built into her palm, use her Floating Limbs fingers to fly like a helicopter, and fire a Hand Cannon. This personifies how Peridot's greatest strength is her technological genius. Without them, she can only Wimp Fight with Steven. Later she does develop a minor talent for Magnetism Manipulation, but that just reinforces the theme about her mind being her greatest asset.
- Lapis Lazuli does not have a weapon. Instead, she has the power to control water. Her official summoned weapon appears to be her fluid wings.
- Jasper prefers to face her challenges head-on and overpower them. Her "weapon" is a spiked-helmet she uses as a bludgeon.
- In "Keystone Motel", we see Ruby summon just one of Garnet's gauntlets. She's very emotional and likely to attack what's upsetting her. Sapphire can be assumed to have the other.
- Left Topaz and Right Topaz wield identical maces that combine into a two-headed version- a sort of pugil stick- when fused. They're silent muscle for Aquamarine and are armed with simple bludgeons to get the job done.
- Aquamarine has a powerful magic wand capable of immobilizing victims, but it's ambiguous if it's a summoned gem weapon or an artifact of Homeworld technology.
- It's also worth noting that when two Gems fuse, their weapons combine into a new one too:
- Opal, a calm compromise between two opposites, turns Pearl's spear and Amethyst's whip into the limbs and string of an Energy Bow.
- Sugilite, the powerful but vicious giant, combines Garnet's gauntlets into a giant meteor hammer with Amethyst's whip as the chain to destroy everything in her path.
- Sardonyx, who is Fun Personified, turns Garnet's gauntlets into the oversized head of a cartoonish hammer with Pearl's spear as the wobbly handle, making the weapon look more like a stage prop to go with how she treats life like a big performance.
- Smoky Quartz, a confident and fun-loving Pungeon Master, wraps Amethyst's whip around Steven's shield to make a giant Killer Yo-Yo.
- Rainbow Quartz 2.0, who combines Pearl's elegance with Steven's fun to create a flamboyant personality, uses a magic parasol.
- Sunstone, a parody of '90s PSA mascots that combines Steven's love with Garnet's motherly authority is probably the strangest example, using a pair of Tricked-Out Gloves with suction cups on them.
- Obsidian, the fusion of all the crystal gems, can combine all four weapons into a sword hilt, which is then dipped in lava to form a flaming BFS to stand as the greatest hero against the tyranny of Homeworld.
- Alexandrite, Malachite, and Stevonnie don't have their own personal weapons. Instead, they use all of their constituent members' weapons interchangeably.
