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), RockSteady, PowerCrystal,MineralMacGuffin.

[[folder:Card Games]]
* The Gem Knight archetype in ''TabletopGame/YuGiOh'' 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.
[[/folder]]

[[folder:ComicBooks]]
* ''Comicbook/{{X-Men}} [[{{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.
* CaptainAmerica villainess (and [[DatingCatwoman sometimes girlfriend]]) Diamondback uses diamonds as throwing weapons... ''fake ones'', of course.
[[/folder]]

[[folder:{{Literature}}]]

[[/folder]]

[[folder:TabletopRPG]]
* ''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 ''DarkSun'' metals are scarce, so obsidian is a typical material for cutting and piercing weapons.
** ''{{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.
[[/folder]]

[[folder:VideoGames]]
* 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.
* 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 ''BirthBySleep'', 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 ''DragonQuest''.
* The Crystal Knight enemies from the ''{{Lunar}}'' series can attack you with crystal-like projectiles or attack from above with its ''lower torso'', which just so happens to be a 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 ''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 ''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 Stinger, the weapon shooting crystal shards like a machinegun.
* 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.
* ''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 ''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.
* 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.]]

[[folder:VisualNovels]]
* ''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]]

[[folder:WebOriginal]]
* 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.
* Shard, a supervillain from the ''GlobalGuardiansPBEMUniverse'', 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]].

[[folder:WesternAnimation]]
* 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]] [[MagicalGirlWarrior Magical Girl Warriors]]. 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.

[[folder:RealLife]]
* [[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]].
