Gem Weapons

Members of the Crystal Gems can summon special weapons from the gems on their body. Each Crystal Gem has their own method for retrieving their weapons, which they each try to teach to Steven in the first episode. Although he is unable to call his weapon at will, it was revealed as a shield. All the weapons have glowing parts that seem to be made of the wielder's stone.

Garnet's Gauntlets


Garnet is the only member of the team to regularly dual wield her weapons, since she also has two gems (one on either palm). She summons them by mentally connecting with the energy of the universe and channeling it through her gems. The gauntlets then appear on her hands from thin air. Both gauntlets have knuckles made of garnets, and can break through stone.

Pearl's Spear


Pearl wields a spear that consists of a glowing cyan blade with similarly colored pommel and a white grip probably made of pearl. To summon it, Pearl trusts in her years of precise training, puts her hands near her forehead, and pulls her weapon from the gem. The blade is wrapped around the grip, only opening when she grabs it. In "Together Breakfast," her weapon was destroyed by the Evil Spirit, but in the next battle, she was able to summon another. Her weapon seems to have three forms, one a wand form but later transforming into the spear form, and the Opal bow and arrow when fused with Amethyst's whip

Amethyst's Whip


Amethyst bears a glowing violet whip. The ends have amethyst gems. The end of the handle seems to be made of amethyst. Amethyst summons her weapon with nonchalance by putting her hand close to her chest and simply pulling it from the gem. The leash has small sharp pieces of amethyst on it, so it causes more damage and makes it harder to break free from a bind. Like Garnet, she can wield two weapons as seen in "Together Breakfast." It's also known it can cut through metal and other materials.

Steven's Shield


Steven wields the only defensive weapon, a spiraling pink shield. His shield also shoots off the beam attaching it to the gem and sends the disc flying. It's shown that the spiral has thorns on it, and the center of the spiral itself is shaped like a rose.

In "Bubble Buddies," he accidentally activates his gem and creates an indestructible bubble shield. Not much is known of the abilities of this weapon or the way of summoning it. The Bubble Shield also seems to be rather heavy despite its size and thickness, given that when Steven and Connie fell into the ocean they sank very fast.

It's unknown if Rose Quartz has the same weapon as Steven, although it is possible that her weapon bore a general resemblance to Steven's shield.

It is also possible if love or emotion summons his weapon or gem, like when Steven ate the Cookie Cat, and his gem glowed, or when he saved Connie, Steven's supposed Love interest.

Opal's Bow and Arrows
Opal's weapon is a long bow that fires arrows made of energy, and the bow is roughly as tall as Opal herself. Due to Opal being a fusion of both Amethyst and Pearl, she can summon either Amethyst's whip or Pearl's spear. She crosses and fuses both weapons together to form her bow. Opal's arrows seem to be made of energy, and are summoned when the bow is drawn back; these arrows cause a large explosion and give off a large amount of light on impact. The arrows are also capable of exploding into multiple smaller arrows to attack multiple targets at once. Targets can also have their remaining gems bubbled after being pierced by these arrows.

Trivia

 * Of all the Crystal Gem weapons, Pearl's spear was the only one destroyed so far, being snapped in half in "Together Breakfast" and being eaten in "Giant Woman."
 * Pearl has a wide range of swords, and teaches Steven to sword-fight in "Steven the Sword Fighter".
 * Pearl also has an axe, which was mentioned in "Onion Trade"
