* Dr. Claw uses a giant ruby as part of his time-freezing beam in ''Film/InspectorGadget 2''.

** ''Pokémon'', in general, has been using this one a lot lately. On top of the gems involves with Cyrus' plot (by the way, Dialga, Palkia, and Giratina each have a plot-uniportant gem that boosts their power considerably), the bulk of ''VideoGame/PokemonRubyAndSapphire'' was about trying to hunt down gems that woke up legendary Pokemon. In ''VideoGame/PokemonBlackAndWhite'', it's a similar situation, except the magic stones ARE the legendary Pokemon. It also introduced elemental gems that give an attack of the same type a huge power boost, but they're common enough to be junk items.

** [[VideoGame/PokemonSunAndMoon In the seventh generation]], items called Z-Crystals are introduced. Equipping the correct ones to your Pokemon allows them to use incredibly powerful attacks known as Z-Moves. Collecting the entire set is the focus of the Island Challenge plot: you get one for each Totem Pokemon and Island Kahuna you defeat, and the others can be found as you travel Alola. Come [[VideoGame/PokemonUltraSunAndUltraMoon the second set of games]], it's discovered that the power of the Z-Crystals is [[spoiler:the "light" produced by [[OutsideContextProblem Necrozma]], which shone down onto Alola and created the Crystals and Totems. Necrozma has since lost the power to produce its light and is in agony without it, but by the time the player meets Necrozma, they have a large collection of Z-Crystals. This means that so long as Necrozma is with the player and their Pokemon, its pain is stopped, and it has the opportunity to temporarily regain its true form.]]

** Also in the recent remake ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' where [[DidYouJustPunchOutCthulhu the power to defeat gods]] and god-like entities can be wielded by those attuned to the "Elements of Harmony", artifacts traditionally depicted as six gemstones. Since the elements were re-activated by the main characters, their powers have been stored within 5 jeweled necklaces and one [[BuffySpeak Big Crown-Thingy]].

* ''WesternAnimation/{{Amphibia}}'': The Music Box which transported the three girls to Amphibia and is ultimately central to the plot of the entire series is fueled by the power of the three Gems embedded in it, each one represents a different aspect of the Self: the blue gem represents heart, the pink gem represents strength, and the green gem represents wit. The heroes spend Season 2 recharging each of the gems one by one ([[spoiler:unaware that they've been imbued with the magic from one of the gems, but recharging the gems drains its magic back out of them]]). The BigBad[='s=] plan after all three gems are recharged is to use the Music Box's portal-opening abilities to invade Earth and become a MultiversalConqueror.

The BigBad[='s=] plan after all three gems are recharged is to use the Music Box's portal-opening abilities to invade Earth and become a MultiversalConqueror.

* ''WesternAnimation/TangledTheSeries''' Sundrop and Moonstone. The Moonstone is causing [[TheKingdom Corona]] to be overrun with Kudzu-like black rocks, so Raps and co. venture out into the world to find it and reunite it with its counterpart (I.E. [[LivingMacguffin Rapunzel]]). And as it turns out, it [[spoiler: would have been a very, very bad idea]]. Meanwhile the villains have the opposite goal of getting the Sundrop for various reasons, which makes it a cross between this and MacguffinTurnedHuman[=/=]LivingMacguffin.

* How many times did various ''Franchise/StarTrek'' series base a plotline on the ship running out of dilithium crystals, exactly? Dozens? [[RecycledPremise A hundred?]]

* A similar plot happens in ''WesternAnimation/ThePowerpuffGirls''. At least twice, and probably several times.

* Through the majority of ''Film/{{Congo}}'' the blue diamonds are wanted for laser communication with satellites. The last few minutes subvert this when said laser gets turned UpToEleven and [[spoiler:the main character destroys the satellite.]] This was a spur of the moment solution, thus the diamonds maintain their MacGuffin status up to that moment.

* Null Crystals from ''[[Website/GaiaOnline zOMG]]''. Their exact origin hasn't been explained yet, but they do seem to have enormous power. Null Crystals have the power to neutralize [[TheForce G'hi]] energy, forcing [[EverythingTryingToKillYou The Animated]] to avoid them at risk of de-Animation. The crystals come in three varieties.

%% Please do not change or remove without starting a new thread.

* The Red Stone of Aja from Part Two of ''Manga/JojosBizarreAdventureBattleTendency'' definitely counts, seeing as the Stone [[spoiler:serves as the catalyst for Kars' ascension to Ultimate Lifeform]], but also as the only thing potentially able to defeat the Aztec God of Fitness.

* The Mox crystals of ''TabletopGame/MagicTheGathering,'' at least in early [[SchrodingersCanon prerevisionist]] stories. They're also this in meta, given that they're five of the [[GameBreaker/MagicTheGathering Power Nine]], extraordinarily expensive, and limited to one per game in formats where they're not outright banned.

* The Infinity Gems from Creator/MarvelComics. They were originally referred to as the Soul Gems, but ComicBook/{{Thanos}} decided to give them a more appropriate name.

* In ''ComicBook/WonderWomanAndTheStarRiders'' (a promotional comic for a show and toy line that were never produced) each of the Star Riders have a magical star shaped jewel that helps them keep the earth safe which the villain steals. The riders get them back, but the villain manages to steal one as she escapes and swears she'll steal the rest again one by one.

* ''ComicBook/TheScrameustache'': Inverted. Sorbon is rare mineral which cause ships to malfunction when mixed in their engines.

* ''ComicBook/DoctorWhoTitan'': "Ghost Stories" has the Doctor enlisting The Ghost to help him track down the three sister gems to the one that gave Grant Gordon his superpowers.

* ''WesternAnimation/{{Moana}}'' has the Heart of Te Fiti, a magical stone holding the powers of a creator goddess. Moana and Maui must return it to its rightful place to stop the blight spreading across the islands and save Moana's home.

* Although non-magical, the Heart of the Ocean was the elusive [=MacGuffin=] that kicked off the framing story of Creator/JamesCameron's ''Film/{{Titanic 1997}}''.

* El Corazon ("The Heart"), an enormous emerald in ''Film/RomancingTheStone''. Subverted in the sequel, ''Jewel of the Nile'', which sounds like a MineralMacGuffin, but is actually... a person.

* The eponymous ''Film/BloodDiamond''.
* The film ''Cash'' revolved around stealing three diamonds owned by three different people. Since they were cut from one original stone, together they provide a {{full set bonus}}.
* The diamond that is the target of the thieves in ''Film/TheHotRock''. It reaches the point that the monetary value of the diamond is forgotten, and Dortmunder believes that the stone is cursed and his life will never run smoothly till he manages to successfully steal it.
* ''Film/SinbadOfTheSevenSeas'' is about Sinbad fighting to retrieve the four sacred gems of Basra that EvilSorcerer Jaffar scattered across various islands.

* The item everyone is after in ''Film/TheGhoul'' is the Jewel of Light; either for its monetary value, or its supposed supernatural powers.
* ''Film/{{Filibus}}'': Much of the film follows the SkyPirate of the title attempting to purloin the diamond eyes of an Egyptian cat statue.
* 'The Eye of God'--the (possibly magical) treasure everyone is searching for in ''Film/MissFisherAndTheCryptOfTears''--is a [[TreasureIsBiggerInFiction massive emerald about the size of a loaf of bread]].

* Creator/JRRTolkien
** The Silmarils from ''Literature/TheSilmarillion'', and to a lesser extent, the rings of the Elves, which are set with diamond, sapphire, and ruby.
** In ''Literature/TheHobbit'', Thorin Oakenshield covets the Arkenstone, or "Heart of the Mountain", a unique precious gem and family heirloom that is lost amongst the treasure hoarded by the dragon Smaug.

* The gems of the Belt of Deltora in ''Literature/DeltoraQuest''.
* The more powerful and plot-important gelstei crystals in ''Literature/EaCycle'', especially the [[CosmicKeystone gold]] and silver varieties.
* Lampshaded brilliantly in the fantasy novel ''Literature/VillainsByNecessity'', with the Spectrum Key: a spherical crystal worldgate broken into six identically-sized pieces in six different colors, each hidden in a different location by a different Hero and protected by a different clever trap. Several characters comment on the colors; one character is from a colorblind species and can't understand what they're blathering about.
* The "Blue Water" sapphire in ''Literature/BeauGeste'' (1924).

* Subverted in an ''Literature/ArtemisFowl'' mini-book that takes place [[{{Interquel}} between the first two novels.]] Artemis goes to a lot of trouble to steal a unique jewel from a group of dwarves pretending to be a human circus troupe. He gives the stock "focus a new laser I'm developing" excuse to dwarf ally Mulch Diggums, who seems sceptical but doesn't push it. Artemis really wants it as a present for his mother, since it matches the colour of his [[DisappearedDad missing father's]] eyes.
* In Alan Garner's ''Literature/TheWeirdstoneOfBrisingamen'', the titular gemstone is part of a magical bracelet that can be used to protect its wearer, but serves a more important purpose in powering the enchantments which keep [[KingInTheMountain Arthur and his Knights agelessly asleep]] in Fundindelve.
* In Creator/SarahAHoyt's ''Literature/DrawOneInTheDark'', the triad is chasing after Tom for a pearl.
* In Creator/AndreNorton's ''Literature/TheZeroStone'', the title stone. Not much to look at, but harder than diamond.
* In Creator/CliveCussler's ''Literature/RaiseTheTitanic'' and the [[Film/RaiseTheTitanic movie adaptation]] it spawned. The mineral in question is Byzanium, which is required to power a new missile defense system for the USA. The trouble is, the last known deposit was on the ''Titanic'' when it sank in 1912.

* The titular MacGuffin in Wilkie Collins' ''The Moonstone''
* The odd black gems in Creator/FredSaberhagen's ''Literature/EmpireOfTheEast''. Nothing much to ordinary sight, but incredibly beautiful to spirits and wizards who could see the inner structure. [[spoiler:But only Ardneh knew that they were originally the magneto-hydrodynamic cores of hydrogen fusion power lamps, from which he could draw enormous amounts of power.]]
* In the [[Literature/TheStormlightArchive War Of Vengeance]], the battles between the humans and the Parshendi were driven by this trope. Each chasmfiend has an enormous gemstone within its body (about the size of a man's head, referred to as "gemhearts"), and each gemheart could pay for an army for months.

* ''Literature/TheAffix'' revolves around a gem that severely messes with probability, to the point where it will [[ClingyMacGuffin return to the keeper it chooses]] if they throw it away. When it's "awake" not only do its powers get exponentially worse, it [[GlowingGem glows]] at night and changes color as it gains strength; the rest of the time it looks like smoky quartz. It's supposedly harder than diamond according to a geologist who once had it, yet it has [[AlienGeometries 11-sided symmetry]] that should be impossible to cut into that hard a stone even if the tools existed to cut it.
* ''Literature/NansouSatomiHakkenden'': In her youth, Princess Fuse receives a necklace of [[Mystical108 108 beads]] as a countermeasure for her [[HereditaryCurse family curse]], the largest eight being marked with the Eight Confucian Virtues. After her MysticalPregnancy, each of her children (the titular Eight Canine Warriors) is born with one of the large beads [[EmbodimentOfVirtue corresponding to their greatest virtue]], granting them a HealingFactor and the ability to sense the other beads. [[TheMagicGoesAway At the end of the story they lose their markings and their powers]], and the Warriors end up simply giving them away to artisans.
* ''Literature/TheFiresStone'': [[MacGuffinTitle The Fire's]] ''[[MacGuffinTitle Stone]]''.

* ''Franchise/PowerRangers'' is quite fond of this. The Power Crystals used in zord piloting in ''Series/MightyMorphinPowerRangers'' season 1, the Zeo Crystal(s) in ''Mighty Morphin''' season 3 and ''Series/PowerRangersZeo'', the Trizerium Crystals in ''Series/PowerRangersTimeForce'', the Animal Crystals in ''Series/PowerRangersWildForce'', the Dino Gems in ''Series/PowerRangersDinoThunder'', the jewels of the Corona Aurora in ''Series/PowerRangersOperationOverdrive''...

* ''VideoGame/RuneScape'': In the Desert Treasure quest, the player must defeat four guardians to retrieve the smoke, shadow, blood and ice diamonds to free [[SealedGoodInACan Azzanadra]] from his pyramid prison.
* The eight elemental crystals from ''VideoGame/{{Mardek}} RPG''. Each of them is is the font of all energy of their type: aside from the basic elements, the Light and Dark crystals are responsible for Good and Evil, the Fig crystal for all thoughts and dreams, and the Aether crystal for all souls and lifeforces. Every planet has its own set, although non-life-bearing planets don't need the Moral or Spiritual ones.
%% * ''VideoGame/SonicTheHedgehog''
%% ** The Chaos Emeralds from the original series, also present in most games.
%% ** The Time Stones from ''VideoGame/SonicTheHedgehogCD''.
%% ** The Master Emerald from ''[[VideoGame/Sonic3AndKnuckles Sonic and Knuckles]]'' onwards.
%% ** The Sol Emeralds from the ''VideoGame/SonicRushSeries''.
%% ** The Chaos Rings from ''VideoGame/KnucklesChaotix''.
%% ** The Precioustones from ''VideoGame/SonicShuffle''.
%% ** The World Rings from ''VideoGame/SonicAndTheSecretRings''.
%% ** The Phantom Ruby from ''VideoGame/SonicMania'' and ''VideoGame/SonicForces''.
* The Crystal Stars from ''VideoGame/PaperMarioTheThousandYearDoor'', and an honorable mention to the pieces of Star Road from ''Mario RPG'', which at least ''look'' the part.

** ''VideoGame/FinalFantasyXII'' has nethicite, which is capable of causing EarthShatteringKaboom|s (and therefore the perfect deterrent)
* ''Franchise/TheLegendOfZelda'' has a bunch of these, usually in the colours green, red and blue to represent the Goddesses and their respective powers (courage, power and wisdom). ''VideoGame/TheLegendOfZeldaALinkToThePast'' has the three Pendants of Virtue; ''VideoGame/TheLegendOfZeldaOcarinaOfTime'' has the three Spiritual Stones; ''VideoGame/TheLegendOfZeldaTheWindWaker'' has the Goddess Pearls; and ''VideoGame/TheLegendOfZeldaPhantomHourglass'' has the Pure Metals. ''VideoGame/TheLegendOfZeldaFourSwords'', ''VideoGame/TheLegendOfZeldaFourSwordsAdventures'' and ''VideoGame/TheLegendOfZeldaTheMinishCap'' all feature the four Elements/Royal Jewels.

* The Moon Crystals in ''VideoGame/SkiesOfArcadia''.
* The red stone in ''VideoGame/ShadowOfDestiny''.
* ''Franchise/SonicTheHedgehog'''s Chaos Emeralds, although how important tends to vary. If it's a side-scrolling game, the Emeralds are an important collectible but aren't important to [[ExcusePlot whatever story the game may have]], outside of accessing the secret ending, [[GoldenSuperMode Super/Hyper Sonic]], and the implication that Robotnik has won by getting them in your stead on the game over screen. In the story-driven 3D games they're often integral to the plot, such as [[VideoGame/SonicAdventure powering up Chaos]] or [[VideoGame/SonicTheHedgehog2006 being used for time travel]], and collecting all of them is a focal point for both the heroes and villains. Also see the Laser-focusing variants section for more examples.
** ''VideoGame/Sonic3AndKnuckles'' also has the Super Emeralds, upgraded versions of the Chaos Emeralds you've already collected.
** For Knuckles, the Master Emerald is also this when it gets shattered and he has to collect all of the shards.
* The Kingdom Stone in ''VideoGame/FreedomPlanet''.

* Null Crystals from ''[[Website/GaiaOnline zOMG]]''. Their exact origin hasn't been explained yet, but they do seem to have enormous power. Null Crystals have the power to neutralize [[TheForce G'hi]] energy, forcing [[EverythingTryingToKillYou The Animated]] to avoid them at risk of de-Animation. The crystals come in three varieties.
** Null Fragments are used in ItemCrafting, and are HandWaved as the reason why some recipes use rather illogical ingredients.
** Transit Crystals are large crystal outcroppings that can repel and de-animate The Animated. When touched, they can teleport a person to its partner crystal, assuming that they are attuned to it. They're used to send people to the Null Chamber.
** The Null Chamber serves as ''zOMG'''s [[HubLevel hub]]. It is filled with "Dark Crystals", which have the power to neutralize G'hi energy, allowing players to swap out and charge rings. In addition, the Null Chamber grants anyone who enters it a form of immortality. If you are killed in the field, you can release your lifeforce and reform at the Null Chamber.
* Somewhat used in Paul's chapter of ''VideoGame/EternalDarkness''. Three gems, a ruby, a sapphire, and an emerald, are needed to open catacombs within a church and proceed through the level -- they seriously are just plain gems, though, with no power of their own. Their color does seem to hold some significance with the game's unique [[ElementalRockPaperScissors element]] system, however, depending on where they're found. Green represents [[SanityMeter sanity]] and the emerald is found in the staff of a priest depicted in a wall carving, and Paul's own staff is used for sanity recovery. The blue gem, blue representing magic, has to be taken from a Horror, a hulking monster that fires bolts of magic from a distance. The last gem is taken after a miniboss fight with a [[AndIMustScream 600+-year-old and very zombified]] [[SacrificialLion Anthony]]. Defeating him allows you to take his ruby eye, red representing strength.

* ''VideoGame/DarkCloud''
** The Atlamillia. There is just one in first game, and it functions as a tool exclusive to the hero. In the sequel, they are three {{Cosmic Keystone}}s that enable TimeTravel and grant [[DeityOfHumanOrigin godlike power]] to anyone who [[GottaCatchEmAll collects all three]]. Note: it is a [[TheEndOfTheWorldAsWeKnowIt very bad idea]] to actually [[SchmuckBait collect all three]]. [[ColonyDrop Very bad]]. Lousy [[NeglectfulPrecursors Ancients]] and their failsafes...
** A more traditional kind of MacGuffin is found in ''VideoGame/DarkCloud 2'': the mineral known as ''zelmite''. In the [[ExtendedGameplay post-game chapter]], Max ventures into the [[BonusDungeon Zelmite Mine]] beneath Palm Brinks merely to go and fetch some of it as fuel for the [[CoolTrain Blackstone One]].

* Practically all gemstones in ''VideoGame/{{Fate}}'' have magical powers, except the Lampshadingly-names Gem of Lost Hopes.

* They are more than just bling in ''VideoGame/TailConcerto''.
* The PC game ''[[VideoGame/JazzJackrabbit Jazz Jackrabbit 2]]'' had the titular character trying to get back the diamond from his fiancée's (the princess's) wedding ring--an ''enormous'' diamond the main villain was using to power his time machine so he could erase rabbits from history.
* In the adventure game ''VideoGame/{{Darkstone}}'', the seven Crystals of Virtue are a combination of this trope and GottaCatchEmAll; once united, they form the [[HolyHandGrenade Time Orb]].
* In platformer ''VideoGame/CactusMcCoy and the Curse of Thorns'' the title character stole the Thorned Emerald for the guy who hired him and was cursed to remain green and spiny until he delivered the jewel to its rightful location.
* The ''TabletopGame/{{Eberron}}'' RTS ''Dragonshard'' is focused around three factions fighting for control of a massive [[TitleDrop dragonshard]], a magical crystal known as the Heart of Siberys. The Church of the Silver Flame and the Umbragen want it for their own purposes while the Lizardfolk just want it to be left alone because of its cultural significance to them.

* The titular gemstones of ''VideoGame/EightEyes'' were said to have been formed in the midst of nuclear explosions, with a king trying to use them to help rebuild the world AfterTheEnd. However, his eight dukes [[spoiler:(the most powerful one is actually a duchess)]] turned against him, stole the gems and banished him to the wastelands. The exiled king's guardsman is charged with fighting off the dukes and retrieving the gems, ''and'' properly aligning them on an altar after defeating the final boss.
* The nine Talismans in ''VideoGame/DragonsCrown'', which are needed to harm the [[FinalBoss Ancient Dragon]].
* The Mystic Orbs in ''VideoGame/KyleAndLucyWonderworld'', which are actually meteorites that are made of pure, magical energy.
* Starting with ''VideoGame/CrashBandicoot3Warped'', the Crystals and Gems become this for many of the ''VideoGame/CrashBandicoot'' games, being sought after by the villains for their great power, or just being a collectible in general if the story isn't important as in ''VideoGame/CrashBash''.
* In ''VideoGame/CrystalsPonyTale'', the main character must find seven rainbow-colored crystals in order to set his friends free.
* ''VideoGame/TheDarksideDetective: A Fumble in the Dark'': The "Druid's Delight" section of the game revolves around the theft of the Sunstone, a big glowing gem that legend says is vital to keeping the sun shining.
* ''VideoGame/DungeonKeeper 2'': The one exit from the [[BeneathTheEarth Underworld's endless caverns]] to the surface world can only be opened with a full set of Portal Gems, which have been scattered throughout the Underworld. You, the VillainProtagonist [[ADungeonIsYou Dungeon Keeper]], seek to claim them from the forces of Good, secure the portal, and unleash your armies on the surface.
* In ''VideoGame/DayOfTheTentacle'', the three heroes are trying to use a time machine powered by a diamond to stop the evil Purple Tentacle from conquering the world. Unfortunately, Dr. Fred used an artificial diamond to power the machine which results in Hoagie being stranded 200 years in the past, Laverne 200 years in the future, and Bernard ending up right back in the present. While Hoagie and Laverne each try to find a way to power their respective time travel pods, Bernard is trying to find a new diamond to serve as a power source for the master unit.
* ''VideoGame/{{Gumshoe}}'' revolves around a private eye who must travel the world finding the five Black Panther Diamonds in order to save his daughter Jennifer, [[HostageForMacguffin who's being held hostage by the mobster King Dom]].

* In ''VisualNovel/MarcoAndTheGalaxyDragon'', the Lizard Stone is a magical gemstone that gives whoever holds it the power of a dragon. Marco wants to sell it, and all the villains want to get their hands on it.

* The Lucky Dime in episode 3 Of ''WebAnimation/{{Ducktalez}}'', as part of a set of magical stones that grant the owner immortality and great power if they are collected. However, during his Heroic BSOD, Scrooge gives it to Magica, who then uses it to buy bubblegum.

* In ''Webcomic/AgentsOfTheRealm'', the [[ClingyMcGuffin amulets]] all have parts of the Provenance in them, the Provenance being a giant magical gem.

* ''WebVideo/TheMonumentMythos:'' Giza Glass is an anomalous form of glass that is formed by unusual lightning (that only comes with a given constellation [[spoiler:and is implied to originate from [[BotanicalAbomination Special Trees]]]]) striking the desert sands near the Pyramid of Giza. While useful as a currency, its main properties come when made into a cutting edge. Not only is it one of the few things to cause a dent in the normally-indestructible [[BotanicalAbomination Special Trees]], but anything severed by it apparently doesn't die, nor lose connection with the whole. Slicing your hand off with Giza Glass still lets you control it wherever it may be, even miles away, and it won't rot. People ''decapitated'' by it are a different story; their bodies seem fine, but they lose the capacity to speak, and their heads just ''float off'', able to mysteriously fly, and will start bloating and growing in size if not supplied with vinegar.

* The Thirteen Treasures of Rule in ''WesternAnimation/ThePiratesOfDarkWater''. [[spoiler: Subverted by the eighth, which became a creature, with prior foreshadowing of other subversions to come.]]
* ''WesternAnimation/PuppyInMyPocketAdventuresInPocketville'' has the Friendship Heart. It is implied to be used for various purposes by the monarch, including activating the Pocketpedia (another [=MacGuffin=]) to find out which pet is suitable for a child and to perform Friendship Ceremonies with. It gets [[DismantledMacGuffin cleaved in half]] by Zull, who manages to get one half for Eva. The other half ends up in Kate's hands. The protagonists will have to go on various quests to send denizens of Pocketville to their rightful owners in order to complete Ava's puzzle and [[TwoHalvesMakeAPlot obtain Eva's half of the Heart]] so [[SaveThePrincess Ava can make her return]].

* The Miraculouses from ''WesternAnimation/MiraculousLadybug'' are a collection of magical jewelry that - when powered by their respective [[OurGodsAreDifferent kwamis]] - bestow their wielder a plethora of superpowers, including their own weapon, enhanced speed, strength, durability, a unique superpower and their own awesome costumes. The two main heroes have the Ladybug and Cat Miraculous, which grant the power of Creation and Destruction respectively (and when brought together, can grant wishes), but other reoccuring ones include the Butterfly Miraculous ([[SuperEmpowering Transmission]]) used by [[BigBad Hawk Moth]], the Bee Miraculous ([[TheParalyzer Subjection]]) used by Chloe, the Fox Miraculous ([[MasterOfIllusion Illusion]]) used by Alya, the Turtle Miraculous ([[DeflectorShields Protection]]) used by Nino, and the Peacock Miraculous ([[MookMaker Emotion]]) used by [[TheDragon Mayura]].

* The Crystal of Gawayn from ''WesternAnimation/{{Gawayn}}'' is a magical crystal which will restore Princess Gwendolyn to her correct size.

** These were practically a dime-a-dozen within the [[WesternAnimation/TheTransformers G1 cartoon]]. Stand out examples include Burmese rubies in the "More Than Meets The Eye" three-parter (powerful enough to serve as a fuel source for the Transformers), the Heart of Cybertron from "Microbots" (the power source of the Decepticons' old warship that can also serve as an InvincibilityPowerUp), the Pearl of Bahoudin from "Trans-Europe Express" (the core of a Cybertronian WeatherControlMachine), and - most famously - the Matrix of Leadership from [[WesternAnimation/TheTransformersTheMovie the movie]], an Autobot talisman that serves as the [[VillainBeatingArtifact only means of stopping]] [[PlanetEater Unicron]].

* Dr. Claw uses a giant ruby as part of his time-freezing beam in ''Film/InspectorGadget 2''.
* Through the majority of ''Film/{{Congo}}'' the blue diamonds are wanted for laser communication with satellites. The last few minutes subvert this when said laser gets turned UpToEleven and [[spoiler:the main character destroys the satellite.]] This was a spur of the moment solution, thus the diamonds maintain their MacGuffin status up to that moment.

* Not dissimilarly, ''VideoGame/CrashBandicoot2CortexStrikesBack'' sees Cortex trying to get his hands on 25 crystals to activate his brainwashing device, while Nitrus Brio wants the 42 gems to blow up the aforementioned device.

* In ''Webcomic/{{Endstone}}'', the title stone and others -- the Toadstone, the Dragonstone, etc. -- can be "rocked" by those with the talent and produce powerful magic.

* A similar plot happens in ''WesternAnimation/ThePowerpuffGirls''. At least twice, and probably several times.

* In ''VideoGame/RuneScape'', players can cut and enchant various gems and make them into rings, amulets, necklaces, bracelets or even bolt tips for a large variety of effects. In the Desert Treasure quest, the player must defeat four guardians to retrieve the smoke, shadow, blood and ice diamonds to free [[SealedGoodInACan Azzanadra]] from his pyramid prison.
* The eight elemental crystals from ''VideoGAme/{{Mardek}} RPG''. Each of them is is the font of all energy of their type: aside from the basic elements, the Light and Dark crystals are responsible for Good and Evil, the Fig crystal for all thoughts and dreams, and the Aether crystal for all souls and lifeforces.

The blue gem, blue representing magic, has to be taken from a Horror, a hulking monster that fires bolts of magic from a distance. The last gem is taken after a miniboss fight with a [[AndIMustScream 600+ -year-old and very zombified]] [[SacrificialLion Anthony]]. Defeating him allows you to take his [[TheWoobie Woobie]] - pardon me, ''ruby'' eye, red representing strength.

* Done in ''Series/PowerRangersRPM,'' where they need a specific black diamond owned by the yellow ranger's family.

* ''VideoGame/SonicTheHedgehog'':

* Not unsimilarly, ''Videogame/CrashBandicoot2CortexStrikesBack'' sees Cortex trying to get his hands on 25 crystals to activate his brainwashing device, while Nitrus Brio wants the 42 gems to blow up the aforementioned device.

* ''WebVideo/TheMonumentMythos:'' Giza Glass is an anomalous form of glass that is formed by unusual lightning (that only comes with a given constellation) striking the desert sands near the Pyramid of Giza.

* ''Franchise/{{Jewelpet}}'', in case the title didn't clue you in.
