Gems in the realm of fiction are often either a battery for some uberfied DoomsdayDevice or just some fancy-dancy decoration. In at least several occasions, an UnclePennybags will simply show off the jewels in question as proof of his wealth. But some people prefer showing off their shiny jewels the violent way, mostly in the form of projectiles. And considering that they're much harder than ordinary rocks, painful injuries will most certainly ensue...''[[OhCrap big time]]''.

May be the result of the ability to turn [[BodyToJewel body parts into gems]].

A SubTrope of DishingOutDirt (since gems are still from the earth).

Compare ElementalEmbodiment (when the being itself is made out of jewels and decides to land a physical blow), CrystalWeapon (when the gemstone itself is shaped into a weapon), PowerCrystal, MineralMacGuffin.

Contrast CrystalPrison.




[[folder:Anime & Manga]]
* ''Manga/InuYasha'': Housenki is an oyster demon with an affinity for jewels, who uses adamantine (the term "diamond" didn't exist at this time) for both offense and defense. The titular character's [[{{BFS}} Tessaiga]] [[VictorGainsLosersPowers takes this ability]], named the [[FlechetteStorm Adamant Barrage]].
* Guren, a FillerVillain in the ''Manga/{{Naruto}}'' anime, had the ability to crystalize any material and turn it into weapons, such as creating snowflake-shaped shurikens from the moisture in the air.
* ''Manga/JoJosBizarreAdventureStardustCrusaders'': Kakyoin's Stand, Hierophant Green, has a technique called Emerald Splash, where it secretes green liquid from its hands that then crystallizes into gems which are then fired in rapid bursts.
* ''VisualNovel/FateStayNight'': Rin Tohsaka's magic involves gems filled with mana which are used as medium for spells like detonating thrown gems.
* The Female Titan ([[spoiler:Annie]]) from ''Manga/AttackOnTitan'' can crystallize her skin in order to protect her weak spot or enhance the power of her punches. With a crystallized fist, she can break the [[LightningBruiser Rogue Titan's]] jaw off with one punch.
* "Diamond Jozu" from ''Manga/OnePiece'' can [[ExactlyWhatItSaysOnTheTin coat his body in a diamond shell]] and enhance his attacks with it.
* In ''Anime/DigimonTamers'', Renamon's signature attack is Diamond Storm, ExactlyWhatItSaysOnTheTin.

[[folder:Card Games]]
* ''TabletopGame/YuGiOh'':
** The Gem Knight archetype are knights with gem-like armor. They can fuse together and become more powerful. Gem-Knight Crystal is their leader and he has the most fusions. The strongest is Gem Knight Master Diamond. He later becomes Cairngorgon, Antiluminescent Knight, and then El-Shadoll Egrystal.
** There's also the Crystal Beasts (Gem Beasts in the original), a group of seven [[AddedAlliterativeAppeal bejeweled beasts]] each representing a color of the rainbow. Their main gimmick is moving to the Spell/Trap Card Zone as Continuous Spells when they would otherwise be destroyed, which is depicted as transforming into their respective crystals. The ace of the archetype is Rainbow Dragon.

[[folder:Comic Books]]
* ''Comicbook/XMen [[ComicBook/{{Marvel 2099}} 2099]]'' gives us Crystalline, a mutant capable of growing beautiful crystals out of nowhere. When in a good mood, she just grows them around enemies to trap them but she is fully capable of projecting them as a torrent of razor-sharp shards.
* Introduced in the early tens is the mutant Bling! (the exclamation point is a part if the name) else bone marrow turned into diamonds, which turned the rest of her body into diamonds and allows her to project razor shards.
* ComicBook/CaptainAmerica villainess (and [[DatingCatwoman sometimes girlfriend]]) Diamondback uses diamonds as throwing weapons... ''fake ones'', of course.
* ComicBook/TheFlash villainess Golden Glider uses gemstones as weapons, ranging from fast-growing crystals to heavy leaden pearls.

[[folder:Films -- Animation]]
* In ''WesternAnimation/MyLittlePonyEquestriaGirlsRainbowRocks'', during the final battle, this is what Rarity's attack against the sirens looks like -- though it might be just as well PureEnergy taking the shape of her diamonds symbol.
* In ''WesternAnimation/MyLittlePonyEquestriaGirlsLegendOfEverfree'', when the Humane Seven start developing super-powers, Rarity's power is the ability to generate a sort of "gem barrier" that can be used both defensively and offensively.

* ''Literature/TheHeroesOfOlympus'' has Hazel, a daughter of Pluto who's the Roman god of death and riches, who can control and use gems and precious metals to attack.

[[folder:Live-Action TV]]
* ''Series/StarTrekTheOriginalSeries'' episode "Arena": Captain Kirk used a primitive cannon to fire diamonds at the Gorn.

[[folder:Tabletop Games]]
* ''TabletopGame/DungeonsAndDragons''
** One possible result of using a [[RandomEffectSpell Wand of Wonder]] was firing a stream of 10 to 40 gems at the target, each doing 1 HitPoint worth of damage.
** In ''TabletopGame/DarkSun'' metals are scarce, so obsidian is a typical material for cutting and piercing weapons.
** ''TabletopGame/{{Greyhawk}}'' has Nystul's Crystal Dagger spell and its improved version, Nystul's Crystal Dirk. They create temporary enchanted weapons that can stun undead and fiends. Otiluke's Diamond Screen is a relative of [[StormOfBlades Blade Barrier]], a glittering wall of summoned razor-sharp shards.
** ''Stormbringer/Elric!''. Olab throw crystal disks at their opponents using a club-like launcher.
** The "Gembomb" spell does exactly that, enhancing low-grade gemstones with explosive power as projectiles.
** In the original ''TabletopGame/TombOfHorrors'' module, one of the very few options to defeat the [[OurLichesAreDifferent Demilich]] Acererak's NighInvulnerability is for a Thief character to throw gemstones at him. Particularly sadistic since the gems in Acererak's crypt are some of the most valuable treasure in the module... and are destroyed if used to attack him.

[[folder:Video Games]]
* In ''VideoGame/CastlevaniaSymphonyOfTheNight'', one of the weapons that you can get early in the game (provided that you [[GuideDangIt stand still in a hole that you just made in the wall for several seconds]]) is the jewel knuckles, which will remain your most powerful weapon for some time.
* Some of Pit's weapons in ''VideoGame/KidIcarusUprising'' fire jewels, such as the Royal Blade and the Crystal Bow.
* Both Crystal Man from ''VideoGame/MegaMan5'' and Jewel Man from ''VideoGame/MegaMan9'' use gem-based attacks. The Crystal Joe from the former's stage also does this.
* ''VideoGame/MegaMan'':
** Crystal Snail's Crystal Hunter from ''VideoGame/MegaManX2'', though it's more of a CrystalPrison type weapon.
** ''VideoGame/MegaManX8'' has Earthrock Trilobyte's Crystal Wall weapon.
* The Gem/Diamond Missile spell from the ''VideoGame/WorldOfMana'' series.
* As one of the D-Link abilities in ''VideoGame/KingdomHeartsBirthBySleep'', Literature/SnowWhite uses jewels as weapons.
* ''Franchise/FinalFantasy'' has several weapons made out of gemstones, up to including the Diamond Sword.
* The Jewel Bag from ''VideoGame/DragonQuest''.
* The Crystal Knight enemies from the ''Franchise/{{Lunar}}'' series can attack with crystal-like projectiles or drop on the heroes from above with its ''lower torso'', which just so happens to be a pointy crystal.
* The ''Franchise/{{Pokemon}}'' move "Power Gem" is this, though it involves channeling light via gems. Also, it counts as a [[RockSteady Rock-Type]] attack.
** There's also the event legendary Diancie, whose signature move Diamond Storm is a FlechetteStorm of diamonds.
* Many high level clubs in ''VideoGame/WorldOfWarcraft'' are made of glowing crystals sometimes the weapon consists of a handle with crystals floating around it. Somehow they are very efficient.
** A few rock giants are actually made of crystal and may throw pieces at you or [[CrystalPrison trap you inside gemstones.]]
* ''VideoGame/DeadRising'' lets you throw a bunch of diamonds at zombies. It's mainly just for stunning them, though.
** With a high enough level (and some skill books in tow) gems become a [[FantasyGunControl a faster-to-find replacement for the shotgun.]]
** In ''VideoGame/DeadRising2'' you can combine gems with a leaf-blower to make an effective shotgun or with a flashlight to make a LaserBlade
* Some of the [[BulletHell danmaku]] in ''VideoGame/{{Touhou}}'' is described as this. And a fair amount ''[[GameplayAndStorySegregation looks]]'' like it, since diamonds are one of the most common bullet types.
* The [[CharacterCustomization Power Customization]] in ''VideoGame/CityOfHeroes'' allows you to change [[DishingOutDirt Earth-based Powers]] into Crystal-based Powers. It's [[AndYourRewardIsClothes purely cosmetic]], however.
* Within ''VideoGame/{{Nethack}}'', gems can be thrown, but make bad improvised weapons. The main benefit is that [[spoiler:valuable gems can be identified from glass by throwing them at unicorns, which also increases your LuckStat]].
* In ''VideoGame/DwarfFortress'' Adventure Mode, gems can be thrown with deadly effect up to and including severed limbs. Much like anything else in the game.
* Several of Mimi's attacks in ''VideoGame/SuperPaperMario'' involve hurling [[MineralMacGuffin rubees]] at you, which you're encouraged to pick up and throw right back at her.
* Chenjesu in ''VideoGame/StarControl'' are [[SiliconBasedLife living crystals]] and [[PlanetOfHats make almost everything]] from crystals. Their ship weapon is "Photon Crystal Shards" -- big gem-like bombs that are near-impossible to intercept, cause great damage with direct hits and even when miss explode in shrapnel.
* ''VideoGame/UnrealI'' has the Stinger, the weapon shooting crystal shards like a machine gun. ''VideoGame/UnrealTournament3'' merges it with the more standard [[MoreDakka Minigun]] into the "Stinger Minigun", primary fire shooting out bullet-sized shards like the old Minigun and SecondaryFire launching much larger chunks with a decent amount of knockback (and able to pin enemies to walls with killing blows) like the Stinger.
* A major aspect of Rarity's playstyle in the fangame VideoGame/MyLittlePonyFightingIsMagic. She can delay gems, straight up launch them, cause them to erupt beneath her opponent, or just summon a massive storm below them.
** Rarity (rechristened Generous Mare) also uses gems to fight in the fangame ''VideoGame/MegaPony''. She can use gems as explosive mines, launch them at the opponent, or surround herself with a shield of them. After beating her, Mega Pony gains the ability to similarly use gems as a shield and launch them at his foes.
* ''VideoGame/{{Tyrian}}'' has the SecretLevel GEM WAR, where you fight a bunch of ships that shoot destructible (and sometimes homing) gems at you.
* Taric the Gem Knight from ''VideoGame/LeagueOfLegends'' wears armour made out of gems, carries a large gem-studded shield and wields a ''massive'' [[DropTheHammer hammer]] studded with sharp gems. His gems are the source of his magic and he can both stun enemies with a dazzling blast of light from his shield and cause his crystalling aura to shatter explosively, shredding nearby enemies, as well as buff up nearby allies with the power of his radiance. Truly, truly, truly outrageous.
* Diamond swords are top-tier weapons in ''VideoGame/{{Minecraft}}''. Other diamond tools (axes, picks, etc.) can also be used as weapons, with varying degrees of effectiveness.
* [[SiliconBasedLife Crystalisks]] in ''VideoGame/{{Borderlands 2}}'' can launch a FlechetteStorm of crystal shards at the player, or a timed, explosive crystal that acts like a sticky bomb.
* ''VideoGame/FTLFasterThanLight'' features extremely rare weapons that fire human-sized chunks of crystal at enemy ships. These crystals can pass through low-level shields and will generally wreck ships like no one's business.
** The Crystal race (obtained from a long sidequest, see below) throw crystals as a ranged attack when facing non-adjacent foes.
** In fact, a ship made out of crystals is the reward for a [[GuideDangIt ridiculously convoluted]] and [[RandomNumberGod RNG dominated]] sidequest, starting out the game with it will [[GameBreaker tear everything apart well into the late game.]]
* ''Videogame/FallenLondon'' has a much more standard version of this justifying exactly why a particularly expensive Diamond Ring ups your fighting capability as well as your persuasiveness. Anyone who's ever gotten punched by someone who didn't take off their jewelry can attest to why.
-->''[[DoubleMeaning A huge diamond always leaves an impression]]''
* ''VideoGame/GranblueFantasy'' has De La Fille, who fights with seven gems which, depending on her version and uncap level, appear as regular gems, fruit-shaped, or turned into weapons. Her charge attacks involve using all of her gems for various kind of attacks.
* Oddly, ''Franchise/SuperMarioBros'''s Daisy forgoes the GreenThumb she usually has in sports games for the power to cause crystals to rise from the ground and punch the ball with [[BodyToJewel a crystal fist]] in ''VideoGame/MarioStrikersCharged''.
* Both VideoGame/SecretOfMana and VideoGame/{{Seiken Densetsu 3}} have the spell Gem/Diamond Missile (respectively), which first causes a large diamond to pop out of the ground and burst into smaller spinning gem fragments, finally shooting straight at the target one after the other. In the latter's case, when targeting enough enemies, the assault is so much, '''it causes slowdown'''.
* In ''VideoGame/KirbyPlanetRobobot'', the four abilities present in the Team Kirby Clash mode get a fantasy makeover, with the Doctor ability resembling an alchemist and substituting gemstones for its usual pills in all of its attacks.
* SSI (Strategic Simulations Incorporated)'s ''VideoGame/GalacticAdventures''. One of the available weapons was the Gemstone, which is fired as a missile. It moves toward its target (sometimes moving a space in the wrong direction) and detonates after moving six spaces, whether it has reached the target or not.
* ''VideoGame/CommandAndConquerTiberianSun'' has a critter known as "tiberian fiend", a horse-sized quadruped that attacks by throwing chunks of Tiberium crystals at its targets.
** ''VideoGame/CommandAndConquerRenegade'' has the Tiberium Flechette Gun, a small nailgun-like weapon that launches shards of Tiberium. It's good against everything except [[ReviveKillsZombie mutants, who it heals]], which makes it a shame that it only appears after mutants take over for most basic enemies.
* The Crystallix armor in VideoGame/RatchetAndClankSizeMatters allows Ratchet to deal crystal based strikes with his Omniwrench.

[[folder:Visual Novels]]
* ''VisualNovel/FateStayNight'' has Rin Tohsaka, practitioner of Jewel Magic. Usually, the jewels are just charged up with a bit of magic everyday to supply greater amount of energy when needed, but they also make good explosives. This also explains why she's such a miser.
** Her Finnish Rival, Luvia, also uses jewels. This is because [[spoiler:Rin's ancestor defeated the twin sister of Luvia's ancestor in the Third Grail War and stole their family's magic.]]

[[folder:Web Original]]
* One Website/{{Darwin Award|s}} winner met his death in a crystal cave. He tried to steal a beautiful crystal stalactite and managed to break it off the ceiling... while standing directly underneath.
* ''Roleplay/GlobalGuardiansPBEMUniverse'':
** Shard, a supervillain, is [[MadeOfIron made of living diamond]]. One of her powers is spraying a cone of sharpened diamond chips at her opponents.
** The Sinister Circle is a group of mystically-inclined villains who each get their power from one of a set of magical gemstones. These guys are evil with a capital EVIL, to the point that even the degenerates in All Hallow's Eve and the Hellfire Club avoid them out of fear. Bloodstone lives up to his name with [[LovecraftianSuperpower "blood control"]] powers; Diamond has [[BarrierWarrior force powers]]; Obsidian has [[DarkIsEdgy darkness powers]]; and Tourmaline has [[PlayingWithFire fire powers]].
* ''Literature/MagicalGirlPolicy'': The leader of the Spirit Guard, Spirit Guard Valor, has an attack which allows her to use crystals to slice away her foes.

[[folder:Western Animation]]
* The ''WesternAnimation/SWATKats'' episode "Chaos in Crystal" had an escaped convict named Rex Shard use a BodyToJewel variant of this after becoming a crystal himself.
* [[EvilSorceror King Sombra]], the [[BigBad villain]] of the ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' episode "The Crystal Empire", seems to have for his main power to grow huge, spiky crystals out of the ground.
** Technically, [[TheHero Twilight Sparkle]] has learned that magic, but it works by manipulating the crystals of the Empire, making it of limited utility elsewhere.
* The Crystal Gems of ''WesternAnimation/StevenUniverse'' are [[TheAgeless Ageless]] {{Magical Girl Warrior}}s from an alien race with HardLight bodies projected from a GemHeart that serves as the source of their powers. They even have ThemeNaming: Garnet, Amethyst, Pearl, [[PostHumousCharacter (formerly) Rose Quartz]] [[MyFriendsAndZoidberg and her son Steven.]]
* Diaspro from ''WesternAnimation/WinxClub'' seems to have power over gemstones as she attacks Bloom with them each time they fight.
* Both the heroes and villains of ''WesternAnimation/LoliRock'' have the power to summon crystals as their main methods of attack, with both a ProjectileSpell variety and the ability to summon it out of the ground.
* Diamondhead in ''WesternAnimation/{{Ben 10}}'' takes this to the point of almost winning the SuperPowerLottery thanks in no part to his unique physiology. He can naturally shoot out crystalline projectiles, create structures made out of diamond to protect him from attacks that surpass his [[SuperToughness insane durability]] and can shapeshift his limbs into weapons. Later shows give him the ability to make his [[StuffBlowingUp projectiles volatile]], create larger structures and the ability to telekinetically move them and the ability to [[CrystalPrison encase his enemies in crystal]].

[[folder:Real Life]]
* [[http://en.wikipedia.org/wiki/Obsidian Obsidian,]] a type of volcanic glass, has been used as the cutting part of weapons. Amazingly enough, obsidian shatters in such a way that its edges are [[AbsurdlySharpBlade sharper than the sharpest metallic blade.]] It is occasionally used for surgical instruments nowadays since it leaves very clean and neat wounds because of that.
* Jade (particularly the nephrite variety) is unbelievably tough, so much that few forces possible for a human being can actually crack it, even today. (Strangely, despite it's toughness, it's slightly soft. It can't be cracked but it can be ground to shape, by diamonds.) Jade is so invulnerable to impacts that ancient Chinese artisans would make anvils of jade for blacksmithing. Consequently, many weapons and even suits of armor have been made of jade, so much that jade is called axestone in some cultures[[http://en.wikipedia.org/wiki/Axstone]].
* [[ImprovisedWeapon Using jewelry as knuckle-dusters]] seems a little [[AwesomeButImpractical financially counterintuitive]], but it can be done, and leaves some painful-as-hell marks.
