Most Gems are able to summon a personal weapon from their gemstone.
Each weapon is highly personalized and unique, being specifically tailored after the tastes and personality of the Gem summoning it to the point where they cease being weapons at all: Rose Quartz and Steven's loving and protective nature is reflected by their 'weapon' being a shield, as well as phytokinesis and healing abilities. The weapon has a strong bond with its user, who is easily able to summon it by will alone; this will is easily stable enough to allow the Gem to seemingly create multiple copies of their weapon for use in dual-wielding or to be thrown in ranged attacks. The same bond also results in the weapon vanishing if the Gem's physical body is destroyed and they are forced to retreat into their gemstone. An example of this occurrence is when Jasper used a Gem Destabilizer on Garnet in "The Return" and Garnet's gauntlets vanished along with her.
As seen in the episode "Bismuth", Gem Weapons can be upgraded by adding components to their 'base'. For example, Garnet's upgrade seems to be metallic knuckles attached to the gauntlets, which can be considered as the base weapon. These modifications seem to persist and become part of the weapon itself, as the next time the Gem summons the weapon it can be clearly seen that the upgrade has been summoned with it (Amethyst's upgraded whip as an example). Summoning the weapons with these upgrades is optional, as Amethyst, Garnet and Pearl have all summoned both versions of their weapons since being upgraded.
Gem Fusions typically wield a combined form of their components' weapons.
Crystal Gem Weapons
Pearl wields a magic spear that consists of a glowing pearl blade with a white grip and a cyan, gold, and white colored pommel shaped like a star. The head of the blade spirals down the upper shaft, becoming less sharp on the lower shaft. The spear changes lengths. In its regular spear form, it is roughly as tall as Garnet, and in its wand form, it is only as long as Pearl's Sword.
Pearl trusts in her years of training and concentration when summoning her weapon. Pearl's is the most summoned weapon out of the Crystal Gems. Like other summoned weapons, it is able to be broken and re-summoned anew. Pearl is seen dual-wielding her weapon in "Ocean Gem", throwing it in "Giant Woman" and "Coach Steven", and firing projectiles from it in "Watermelon Steven", "On the Run", and "Bismuth".
As of the episode "Bismuth", her spear is upgraded to be able to turn into a trident. However, she is still able to summon her spear without the trident arms attachment. The spear's Trident Form was first used in "Bismuth" after being created and being used in training, this form appears once again in "Reunited" during the fight against Yellow and Blue Diamond.
Amethyst bears a multi-tailed dark violet whip able to take on one, two, or three tails depending on the task at hand. It has a cross-guard in the form of a lavender star. The lash is dark purple and is divided into three different segments with spiked balls on the ends. Multiple shards of amethyst are embedded on the main lash, which inflicts additional damage and further restrains the target. Her whip has a purple amethyst as the pommel and the handle itself is purplish gray. She is seen using her one-tailed whip for smaller tasks, her two-tailed whip for regular combat, and her three tailed whip for larger tasks and occasional dual wielding.
Amethyst summons her weapon with confident nonchalance by putting her hand close to her chest and pulling it from her gem. Her whip has strong durability and elasticity, being able to support Sugilite's Flail and cut through metal and other hard objects. She is seen summoning her weapon in her palms in "Together Breakfast", using momentum to quickly stretch it in "Friend Ship", and lashing it hastily to create an explosive energy wave in "On the Run".
Overall, Amethyst's whip is the least summoned weapon out of the Crystal Gems, as she relies more on her proficiency in shapeshifting to solve her problems. Later in the series run, however, this trend begins to reverse as Amethyst develops her self-esteem and becomes more comfortable with her default form.
In the episode "Bismuth", Amethyst's whip is upgraded to be able to summon a spiked ball on each tail of the whip in place of the usual amethyst pieces. However, she is still able to summon her whip without the flail bludgeon attachment. The whip's Flail Form is first used in "Bismuth" after the form being created and used for training, this form is also used in the episode "Earthlings" against Jasper and one more time in "Reunited" against Blue and Yellow Diamond.
Steven's/Rose's/Pink Diamond's Shield
Steven wields his mother's weapon: a spiraled pink shield. The spiral is decorated with light pink rose thorns, and its center symbol is shaped like a rose. When struck with an attack, it appears to generate a sound wave that negates Gem magic, as it disrupts Lapis Lazuli's control over her water constructs in "Ocean Gem" and Pearl's holograms in "Sworn to the Sword". He is capable of summoning it in larger sizes, and repeatedly in a short space of time; however, as he is still a novice weapon-wielder compared to the other Crystal Gems, this can take a noticeable toll on his stamina.
In "The Return", Steven is able to conjure a larger version of the shield, which successfully deflects the Gem Warship's laser. However, summoning the larger shield drains much of Steven's energy, enough to force him to his knees, rendering him nearly unconscious.
In "Sworn to the Sword", Steven is shown to have greater control over the shield, expanding it to take on multiple attacks without any noticeable fatigue. It was also shown that the shield can act as an offensive weapon if used correctly. The shield was capable of cutting through the many Holo-Pearls and even released concussive shock waves to knock several away at a time.
In "Friend Ship", Steven was shown to have gained a degree of mastery with his shield, summoning the larger variant to stop a falling rock from hitting Garnet. He later summoned it again in its smaller variant, throwing it with enough accuracy to hit and momentarily stun Peridot. However, after summoning the larger variant a second time to provide cover for the other Gems, Steven began to show signs of fatigue and exhaustion which were previously observed in "The Return".
In "The Test", Pearl states that one of Steven's greatest accomplishments is being able to summon his mother's shield. However, he is usually seen summoning a bubble shield.
In "Crack the Whip", Stevonnie demonstrates the ability to summon and utilize this shield as well, and they use it together with Rose's Sword to fight Jasper. They manage to successfully block and repel her helmet-enhanced headbutt, then they throw the shield at her as a distraction in order to strike her on the head, with enough force to poof the Corrupted Gem that Jasper was riding in the process, forcing her to retreat.In "Bismuth", Steven casually summons his shield to show it to Bismuth, indicating that he now has a much better control of his ability to summon his weapon.
In "Change Your Mind", Steven's disembodied gem summons both a regular shield as well as a shield bubble that surrounds him. This shield is markedly different in appearance - it is made of multiple geometric panels (shown are triangles and pentagons), which disappear individually. Rather than a round shield with a rose-and-thorns design, these panels are completely unadorned. This shield is tinted in Pink Diamond's pink rather than Rose's pink. It may be possible that Pink Diamond changed the default appearance of her shield, as she did her own, when she became Rose; this may be her "original" shield. White Diamond states "Don't you raise your shield at me", though it is unclear if "you" means Pink or Steven. Its simplified, almost mechanical appearance may also merely reflect Gem Steven's incompleteness and single-minded devotion to reuniting with his other half.
In "Keystone Motel", Ruby is shown wielding a small, amaranth-purple gauntlet that has a darker maroon stripe on the shaft's upper half, along with a pinkish-red glove. While similar in design to Garnet's gauntlets, it appears smaller and does not have the same motif, lacking the knuckles that Garnet's gauntlets feature. Ruby's gauntlet has mitten shaped finger placements. Ruby is capable of putting a great deal of force behind it when swung, enough to completely smash a table in The Best Diner in the World when angry.
Homeworld Gem Weapons
Jasper's Crash Helmet
Jasper's weapon was an orange, square helmet with a diamond-shaped extension on the front and a visor to protect her eyes and gem. Like Rose, she wielded an object of defense, but Jasper used it primarily for offense. When she used her helmet, she often charged or headbutted her opponent.
Holly Blue Agate's Electric Whip
Holly Blue Agate's weapon is a long, light blue stock whip with electricity coursing through it. The handle is a dark violet-blue adorned with a holly blue agate guard and a lighter violet-blue pommel. She is proficient enough with it to cast the lash in a straight line towards her opponents. When the lash is cut, however, the current of electricity stops, allowing the lash to be handled safely (as seen in "That Will Be All").
Ruby (Eyeball)'s Chisel Knife
Ruby (Eyeball)'s weapon is a crimson and maroon, flat-ended chisel knife. The top forms a triangle. Eyeball is also able to summon the hilt of her shiv out of her gem, such as Pearl and Amethyst summoning the hilts of their weapons from their gems.
Both Topazes' weapons are shorter one-headed mace variants. Their maces are colored yellow, are crystalline in appearance, and have a brown hilt. Both Topazes are shown to be very proficient with their weapons, spinning them very fast to build momentum before impact and using their strength to break through something as strong as Steven's Bubble Shield. When fused, they can manifest both maces as a double-headed variant, changing their combat style to catch opponents off-guard. Two Topaz in "Familiar" who stand and guard Blue Diamond's Pool Chamber, each also wield same maces.
Two Topazes who guard Yellow Diamond's Bubble Chamber each wield an axe.
Garnet usually dual wields weapons on both hands and are the only weapons to regenerate with a different design, being less elaborate than her previous gauntlet. Her gauntlet covers half of her lower arm at its normal size and her whole lower arm when she increases its size. Before regenerating, her gauntlet had a red and light red spiral design around the entire shaft, red and dark red fingers and fingertips, and contained the same star motif on the tops and bases of the gauntlets.
After regenerating, her gauntlets became less elaborate, (although larger and more vivid) having one dark red and one violet-red stripe on the top and bottom halves of the gauntlet. The fingers are a lighter violet red with black fingertips and the base of her gauntlets no longer adorns the star, instead being a solid orange color. The back of her palm, however, keeps the same yellow star motif, albeit more orange-like. Her gauntlet has knuckles embedded with light red garnets, which are strong enough to easily break through rock. Garnet's gauntlets are presumably a combination of Ruby's gauntlet and Sapphire's weapon, although it is unknown if the latter even has one, having never been shown summoning one. Unlike other fusion weapons, it is summoned complete instead of Garnet having to summon both weapons and fuse them. They also appear complete when being made into other weapons, so it is possible that Garnet's gauntlet is merely Ruby's gauntlet that has been enhanced by Sapphire's presence (similar to how Ruby's presence affects Sapphire's future vision).
She summons it by mentally connecting with the energy of the universe and channeling it through her gems. This makes her entire lower arm glow a bright red color and allows her gauntlet to materialize from her gem. When her gauntlet disappears, it glows the same bright red color as it does when it materializes. Slowly losing its shape, it turns into a small star that moves back into her gem. She can also launch it as a rocket fist as seen in "Watermelon Steven" (which is proven to make her hand temporarily disappear in "Reformed") and increase its size as shown in "Warp Tour" and "Garnet's Universe".
As of "Bismuth", Garnet's gauntlets have been equipped with what appears to be spiked brass knuckles. However, she is still able to summon her gauntlets without the brass knuckles attachment. The gauntlets' brass knuckle form is first used in "Bismuth" with the form being created and being used in training; this form appears once again in "Reunited" in the fight against Blue and Yellow Diamond.
Opal's Energy Bow
Opal's weapon is an opalescent recurve bow that fires arrows made of a light-based energy. The bow is roughly as tall as Opal herself. Due to Opal being a fusion of Amethyst and Pearl, she can summon both Amethyst's whip and/or Pearl's spear at will and fuses both weapons together to form her bow. Flashes of light appear when she summons it and a gust of the wind that blows Opal's hair back is created upon impact of the weapons fusing. Pearl's weapon forms the limbs of the bow while the lash and handle of Amethyst's whip become the string and grip, respectively. Her arrows are summoned when the bow is drawn back. These arrows cause a large explosion and emit a bright light on impact, as well as bearing a striking resemblance to the energy blasts emitted by Pearl's spear. The arrows are also capable of splitting into several smaller arrows and either attacking multiple targets at once or overwhelming a single target. Targets pierced by these arrows can have their remaining gems bubbled by them as well. When fired by Alexandrite, the arrows can take on the silhouettes of Garnet, Amethyst, and Pearl (as seen in "Super Watermelon Island").
Referred to by Steven as a "wrecking-ball-thingy", Sugilite's weapon is a giant flail with a purple ombre design formed out of Garnet's gauntlets and Amethyst's whip. A much longer version of Amethyst's whip acts as the supporting lash of the flail, and a giant version of Garnet's interlocked gauntlets act as the mace. The mace is adorned with a silver star-shaped ring that connects the bludgeon to the lash of the flail. There are two sugilites on the handle of the flail, one on the end of the handle and a smaller one connecting the handle to the whip. The flail is enormous, capable of causing mass destruction when swung. When used properly, the flail can smash hundreds of pillars into rubble in minutes. She uses its momentum to destroy large objects and utilizes its surface area to disrupt the balance of her opponents as seen in "Coach Steven". When used to constrict an enemy, the mace seems to disappear, leaving only the lash wrapped around its opponent (as seen in "Super Watermelon Island").
Sardonyx's War Hammer
Sardonyx's weapon is a giant war hammer, formed by fusing Garnet's gauntlets and Pearl's spear together. The head of the hammer is light red-orange, with both sides being shaped like a fist to represent Garnet's gauntlets. They are joined by a grayish-purple rectangular section with the black handle going through it. The base of the hammer has a pommel similar to that of Pearl's Spear, and the top has a yellow five-pointed star connecting the head of the hammer to the handle. It is considerably large, as the head of the hammer is taller than Sardonyx herself. Sardonyx wields her weapon much like a bat while utilizing her anatomy manipulation ability to gain momentum and raise the precision of her strikes. The handle is extremely flexible in order to withstand the impacts of the hammerhead without breaking. When the weapon disappears, it transforms into a cloud of dragonfly-shaped sparkles that fly away and dissipate. Sardonyx's hammer can also be turned into a drill by spinning rapidly, as seen in "Friend Ship". In its drill form, it is capable of drilling through thick walls and stone that the fusers could not break through with their weapons. It is powerful enough to destabilize a fusion of five Rubies in a single blow.
Smoky Quartz's Yo-Yo
Smoky Quartz's weapon is a large yo-yo, created by fusing Steven's shield with Amethyst's whip. They can use it to attack from a distance with complicated maneuvers, pull themself out of the way of enemies, and even create vortexes of air. They also show the ability to summon and wield up to three yo-yos at once (one per hand). In "Know Your Fusion", it is shown that it can take on the form of a helicopter rotor.
As mentioned in the "Guide to The Crystal Gems", Alexandrite is capable of wielding all of the fusers' weapons. In addition, she is able to wield fusion weapons and even transform one weapon into another, seen in "Super Watermelon Island" when she turned Sugilite's Flail into Sardonyx's War Hammer. It is currently unknown if Alexandrite has her own unique weapon.
Topaz's Pugil Mace
Topaz wields a long double-headed mace as a weapon. The double-headed mace is a combination of her components' single-headed maces. The heads of the mace are colored yellow and are crystalline in appearance, while the hilt of the weapon is colored brown. A single blow with this weapon can knock Steven back and render his shield somewhat ineffective.
Rainbow Quartz 2.0's Parasol
Rainbow 2.0's weapon is a pink parasol with a white star design and a white handle, created by fusing Steven's shield as the canopy with Pearl's spear as the handle. Rainbow can use the parasol to float through the air, and they can ride it like a broomstick, leaving a rainbow-colored trail-boost behind them.
Sunstone's Suction Cups
Sunstone can summon red gauntlets with pink suction cups attached to them, a combination of Garnet's gauntlets and Steven's shield. The gauntlet portion, interestingly enough, resembles Ruby's gauntlets more than Garnet's. Sunstone can use their suction cups to scale large surfaces, using them to climb up Pink Diamond's Ship in "Change Your Mind".
Obsidian forms the hilt of their sword by combining Pearl's spear, Steven's shield, Garnet's gauntlet, and Amethyst's whip; then, Obsidian smelts the blade of the sword by opening up a third mouth full of lava and sticking the hilt into their mouth. The red-hot sword that they pull out of their mouth is then capable of slicing through nearly anything, as it destroys Yellow Diamond and Blue Diamond's ships with seemingly little effort.
Video Game Weapons
Hessonite wields a sword from her gem. The sword mostly resembles a comple straight bladed cutlass or a basket hilt sword. This is seen by the straight blade, the guard that wraps round the hand but not completely covering it unlike that of a basket hilt, and the presence of a quillon behind the blade.The sword has an orange-yellow handle, Zircon-hair like shape, and a red-orange pommel with sharp, red-orange ends. The blade is pink in color.
- Most of the Crystal Gems' weapons are based on human weapons from the European medieval era: Garnet's gauntlets, Amethyst's whip, Pearl's spear, Steven/Rose's shield, Rose's sword, Opal's longbow, Sugilite's flail, Ruby's gauntlet, Sardonyx's war hammer, and Obsidian's sword.
- Jasper's helmet seems to be of a more modern/futuristic design – perhaps to contrast how "outdated" the Crystal Gems are compared to modern Homeworld Gems.
- However, since Jasper was made halfway through the Rebellion (as revealed in "Beta"), and has presumably had her helmet since she first emerged, the modern/futuristic design is most likely just a coincidence.
- Smoky Quartz's yo-yo is not traditionally a weapon, let alone a medieval one. However, yo-yos have been around for a long time, having first been historically mentioned in 500 B.C. They are thought to have originated from China. There have been records of historical Filipino hunters using yo-yos as hunting weapons.
- Since Rainbow Quartz's weapon is a parasol, and Sunstone's is a pair of suction cups, it seems that Steven's fusions typically do not make traditional weapons.
- Jasper's helmet seems to be of a more modern/futuristic design – perhaps to contrast how "outdated" the Crystal Gems are compared to modern Homeworld Gems.
- Like the Crystal Gems' outfits, their signature weapons have stars on them, with the exception of Steven, Ruby, and Obsidian.
- Garnet's gauntlets have large stars on the back of the hand and previously had star designs on the bottom surface, around her wrists.
- Amethyst's whip has a lilac star-shaped cross guard.
- Opal's bow has two yellow star-shaped crossguards that are identical to Amethyst's whip.
- The bludgeon on Sugilite's flail is adorned with a silver ring shaped like half of a star.
- Pearl's spear has a star-shaped pommel.
- Sardonyx's war hammer has a star on the top end of the shaft.
- The facets of Smoky Quartz's yo-yo form a star.
- Rainbow Quartz's parasol has a star design on its surface.
- The backs of the glove part of Sunstone's suction cups feature stars.
- Of all the Crystal Gems' weapons introduced so far, Sugilite's flail is the largest.
- It also has the longest reach of any melee Gem weapon.
- As of "Change Your Mind," this record was broken by Obsidian's greatsword.
- Each of the Crystal Gems' weapons matches the color palette of their owner.
- It is unknown if all Gems have the ability to summon a weapon from their gemstone.
- Gems occasionally use physical weapons to replace or supplement their summoned weapons. Every material weapon used by the Crystal Gems during the war was created by Bismuth.
- Pearl owns a collection of swords, and once owned a magical ax.
- Rose Quartz owns a vast collection of flails, battle axes, armor and her sword.
- Peridot often used her limb enhancers as a weapon before losing them. These artificial limbs have fingers which are disconnected from the wrist and are green and black. They give Peridot several abilities, such as a tractor beam, a blaster, and a finger screen, as well as allowing Peridot to scale walls or use her fingers to rotate (similarly to a helicopter) and fly away.
- Aquamarine uses a wand in her fights. Although disguised in her hair, Aquamarine's navy blue bow can unfold and straighten into a wand which has tractor beam-like powers similar to those of Peridot's Limb Enhancers. This weapon is so potent it can stun multiple enemies at once, including large fusions such as Alexandrite. This weapon is not summoned but rather carried on her person.
- In a flashback in "A Single Pale Rose", a Gem soldier uses a flail against Garnet during the Rebellion.
- Garnet, Steven, and Pearl have been shown to summon weapons of different sizes, while Amethyst has the ability to alter the number of tails at the end of her whip.
- Gem Weapons are modifiable, as shown by Bismuth when she gave each of the Crystal Gems, with the exception of Steven, upgrades to their weapons.
- Pearl's spear takes on the form of a trident.
- Garnet's gauntlets are given spiked brass knuckles.
- Amethyst's whip gains a "morning star" at the end of each of its tails.
- The episode "Bubbled" reveals that different Gems of the same type can have different Gem Weapons, as the Crystal Gem Ruby and "Eyeball" Ruby have different weapons, a gauntlet and a chisel knife, respectively.
- Some Fusion Gems (like Stevonnie, Alexandrite, and Malachite) have not been shown to have their own unique weapons, but instead, share the arsenal of the Gems that compose them. Stevonnie has Steven's shield, and Malachite has Jasper's crash helmet and Lapis Lazuli's hydrokinesis and water wings. Alexandrite has even been shown to summon the weapons of her components' fusions.
