Rock Theme Naming

Go To

No, this trope isn't about people named after rock stars. Some fictional characters (and some real people) are named after things that can be dug from the ground, such as rocks, gems, metals, and minerals.

Naming women after jewels is the least conspicuous version of this — it is quite common for girls to be given names like Ruby, Opal, or Crystal. Using other variants tends to attract attention.

    Anime & Manga 
  • Beast King Golion (The original source of Lion Voltron) has the original five pilots with surnames which are types of metal: Akira ("Keith") Kogane — "gold", Isamu "Lance" Kurogane — "iron", and so on. (Princess Fala/"Allura" doesn't fit into the scheme.)
  • CLAMP's four-volume series Wish uses this for the majority of named characters. The theme is precious and semi-precious stones. Names include: Kohaku ("Amber"), Hisui ("Jade"), Ruri ("Blue Glass"/"Lapis-lazuli"), Hari ("Crystal"), Koryuu ("Garnet"), Kokuyo ("Obsidian"), Sango ("Coral"), and Shinju ("Pearl"). There may be more.
  • All the important characters in Gaist Crusher have this: the main character got Shirogane ("silver"), Kongou(ji) ("Adamantine"), (Shin)dou ("Copper"), Quartz(heart) ("Icy cold"), Kokuyou ("Obsidian"), Sango ("Coral"), Hisui ("Jade"), Kohaku ("Amber") and Rock is... Rock. But specifically those Volcanic rock since it corresponds his full name.
  • In Inuyasha, the three characters from the youkai exterminator village who are actually named all have names related to semiprecious stones: Sango (coral), Kohaku (amber), and Kirara (mica).
    • The first movie introduce the villain Menomaru (agathe), with his goons named after crystal and glass.
  • Magnes is Latin for "lodestone", or magnetic iron. One example of an entity named for such is the Wizard in Mega Man Star Force 3 - the one piloting the rocket that almost blew up at Echo Ridge Elementary and which Mega Man uses to transfer into Meteor G at game's end.
  • Sailor Moon's villains are frequently named after minerals or jewels, with varying obscurity. Some groups of villains have their own theme, e.g. the Shitennou's names all end in "ite", the Black Moon Clan members are named after precious stones, etc.
    • From the Dark Kingdom: Beryl, Jadeite, Nephrite, Zoisite, and Kunzite.
    • From the Black Moon Clan: Demande, Rubeus, Esmeraude, Sapphir, Koan, Beruche, Petz, and Calaveras.

    • From Shadow Galactica: Sailor Iron Mouse, Sailor Aluminum Seinen, Sailor Lead Crow, Sailor Tin Nyanko and Sailor Heavy Metal Papillon.
  • In Shaman King, several of the Native American shamans are named after metals: Silva (silver), Goldva, Kalim (from kalium, the German word for potassium), Nichrome (who has a brother named Chrome), Bron (bronze), Rutherfor (rutherfordium), and Zinc.
  • In Tsukihime, the Meido twins are named Hisui (Jade) and Kohaku (Amber).
  • The manhwa Les Bijoux used this in spades. The main character had a Literal Split Personality - he was Lapis, she was Lazuli, and both of them hated prince Sapphire (well, Lazuli a tiny bit less, to his/her confusion and anger).
  • In Cardcaptor Sakura, Eriol's guardians/servants, Spinel Sun and Ruby Moon, are both named after gemstones often mistaken for each other.
  • Yaiba has the First Class Soldiers in the Pyramid arc named after precious stones (Sapphire, Ruby, Emerald and Diamond). Plus, when they combine they form a being called "Jewel".

  • Jewelpet
  • Word of God revealed that the true names of Dragon Ball Z's Androids 17 and 18 were Lapis and Lazuli, respectively.
  • Love Live! Sunshine!! has the Kurosawa sisters, Dia and Ruby (Dia's name is short for "diamond"). According to an interview with Dia, it's a tradition in the Kurosawa family to name their daughters after precious stones, though she mentions that it's unusual to be given English names like hers and Ruby's.
  • Due to the fact Pokedex Holders are named after the Pokémon games, the second, third, and fourth generation main characters of Pokémon Adventures use this. Gold, Silver, Crystal, Ruby, Sapphire, Emerald, Diamond, Pearl, and Platinum all count.
  • The gems in Land of the Lustrous are named after the minerals their bodies are made of. The main character is Phosphophyllite, and other prominent characters include Cinnabar, Rutile, Diamond, Bort (rough, low quality diamonds), Antarcticite, Ghost Quartz, and Cairngorm. The only exception to the theme naming is their leader, Kongou/Adamant.
  • The Stone World Villagers in Dr. Stone are all named after rocks and minerals. The only exceptions are Suika, Genbu, and a nameless man. (Although Suika is justified as being a nickname.)
  • Rich Bitch Erika Koenji (a minor antagonist from early chapters of Skip Beat!) is always accompanied by her three bodyguards/ servants/ henchmen nicknamed Emerald, Sapphire, and Ruby. Each has an earring that corresponds to the gemstone they're named after, and the author of the series affectionately calls them "The Jewel Squad." Erika even has plans to add international acting and modeling superstar Ren Tsuruga to her squad as "Diamond" (her favorite stone).
  • The Kujyo twins in Wasteful Days of High School Girls are named after gemstones: Hisui (emerald) and Kohaku (amber).
  • JoJo's Bizarre Adventure, in conjunction with its Musical Theme Naming, has most protagonist stands follow this: Star Platinum, Crazy Diamond, Gold Experience, Stone Free, and, although it's a little bit of a stretch, Tusk.
    • There's also a random few characters besides the main character of each part — Hierophant Green's Emerald Splash attack, as well as the literal "I am a Rock".

    Comic Books 
  • Marvel Comics's Crystar Crystal Warrior is made of this trope. Names include Crystar, Moltar, Feldspar, Ambara, Stalax, Ogeode, Malachon (for Malachite), and their whole planet is named Crystallium.
  • Similarly, DC Comics' Amethyst, Princess of Gemworld.
  • In Sonic Universe, Silver meets a new character named Gold. They both have Psychic Powers (Silver has telekinesis, Gold has telepathy), semi-identical markings on their hands (Silver) and forehead (Gold) and they are both trying to save their universe from destruction.
  • Amethyst, Princess of Gemworld: Gemworld royalty are normally referred to by their royal title and house name—i.e., the series lead is properly known as Princess Amethyst, her birth parents were Lord and Lady Amethyst, etc. Becomes a bit confusing when royal houses have several children of the same gender; in the original mini-series alone, there were three princesses of the House of Emerald, all of which were named as "Princess Emerald" by lifelong Gemworlders (Amethyst would later nickname the youngest princess "Emmy" to differentiate her).

    Fan Works 
  • In Shining Pretty Cure, not just with the main heroines and the mascots, but the locations, which show a heavy light and gemstone motif. The story is set in Luminous Town, they attend Bright Academy, and congregate at Gemstone Park by Lake Lapis...
  • All the Phoenix Corporation Agents in Akatsuki Kitten: Phoenix Corporation Overhaul have a Jewel-based codename, which have been adopted as their actual names in many cases. There are only three that don't: Agent Chimera (Tiger's Eye) and Agent Nightingale (Pearl and Obsidian) consider their jewel-based codenames to be too long and cumbersome for everyday usage. Agent Silk, for reasons unknown, keeps his hidden from everyone. The only person to actually know his is the author, and she's not telling.
  • In A Song of Grumbling & Cotton Candy, Jem insists that her Awesome McCoolname is really just "Jem". Pizzazz doesn't buy it. In reality, her name is "Jerrica Benton", but it's a secret:
    Jem: I... are you asking for my last name?
    Pizzazz: Yeah. Honestly, yes, yes I am. I know, I'm horrible. I don't remember your name. You're just... You probably know mine.
    Jem: Phyllis, right? Honestly this might surprise you but... Jem actually is my name.
    Pizzazz: [thinking] Oh bullshit. Just like Clash, exactly like Clash. Then why does your credit card say Constance, Clash? Huh? Wanted me to believe you were naturally a redhead too, didn't you?

    Films — Live-Action 
  • Used in Akira Kurosawa's film August Rhapsody (the one about Nagasaki, with a guest appearance by Richard Gere as a half-Japanese pinapple company heir), when the Grandmother is listing all the metal-themed names of her siblings (Gin/silver, Kin/gold, Tetsuo/iron, etc., there were a lot of them) to jog her memory and see if Gere's character's recently deceased father could be among them, to the greedy hope of the Grandmother's grown children.
  • In the Hellboy films, the redshirts at the BPRD all have mineral-themed names such as Steel and Flint.

  • In Gene Wolfe's Book of the Long Sun, robots are named after gems, metal, or rocks, while human males are named after animals or animal products (e.g. the main character Silk) and human females are named after plants (e.g. the love interest Hyacinth).
  • In the Discworld books, all trolls are named in some way after rocks or minerals. Female trolls may have the names of precious stones (such as "Ruby"), whereas males tend to be named for more mundane minerals or geological terminology (such as "Detritus"). Trolls even grow to look like the specific minerals for which they are named, making these Prophetic Names — a phenomenon which is called "metamorphorical rock" in-setting, but which isn't actually understood there. One book, on the other hand, features a troll called Big Jim Beef, which is explained as a "macho" nickname, similar to a human being called Rocky. Additionally, the word "rock" itself to refer to a troll generically is a rather nasty insult, though a troll might call himself Rock as a proper name (such as Galena using "Rock Cliffe" for his Stage Name in Moving Pictures).
  • In J. R. R. Tolkien's Middle-Earth (The Lord of the Rings, etc), the hobbits have an acknowledged tradition of most often naming females after flowers or gemstones: e.g. Diamond Took, Esmeralda Brandybuck or Ruby Gamgee.
  • In Double Act by Jaqueline Wilson, the protagonists are twins called Garnet and Ruby. Their mother was called Opal.
  • In Flavia Bujor's The Prophecy of the Stones the heroines are called Jade, Amber and Opal.

  • In Nina Kiriki Hoffman's book A Fistful of Sky, the five kids in the LaZelle family are all named after minerals or precious stones. The girls are named Opal, Gypsum, and Beryl, while the boys are named Jasper and Flint. It is implied that this is a family tradition, as they have cousins named Amethyst and Chalcedony.
  • The Ordinary Princess: All seven royal daughters of Phantasmarania are named after jewels: Diamond, Opal, Emerald, Sapphire, Crystal, Pearl, and Amethyst.
  • In Night World, lamia vampires often have nature-themed names, including gemstones. This includes Opal, Jade, Garnet and Jasper.

    Live-Action TV 

  • When they're not using Animal Theme Naming, Australia's national sports teams (especially women's teams) tend to do this:
    • Opals (Women's basketball)
    • Sapphires (Women's under-21 basketball)
    • Gems (Women's under-19 basketball)
    • Pearls (Women's intellectual disability basketball)
    • Diamonds (Netball)

    Video Games 
  • Tales of Hearts has its main characters named after minerals: Shing (last name Meteoryte), Kohak, Hisui, Innes Lorenz(inite), Beryl Benito, and Kunzite. For those of you who missed it, Kohak and Hisui are sister and brother, and their names are Amber and Jade respectively in Japanese. Supporting characters are named Chalcedny, Peridot, Byrocks, Paraiba... and the old party contains names like Iola, Tekta, and Labrado(rite)... and the Big Bad is Creed Graphite. Early-game villains are named Grossular and Kornerupine, while the Big Bad's posse consists of Corundum, Clinoseraph, Chlorseraph, Geo Strigau, and Incarose. Look them all up. The only one not to follow this theme is Gall Gruner, added in Hearts R. This is a hint that he is not from this world
  • The Jumi in Legend of Mana are all named after the gemstones in their cores. So when you run into a Jewel Thief named Sandra, a Gem Merchant named Alex, and hear of a Jumi Knight called Alexandrite, it's not hard to put two and two together.
  • Pokémon:
    • Several game titles feature this. Second-generation games Gold, Silver, and Crystal; third-generation games Ruby, Sapphire, and Emerald; and the fourth-generation games Diamond, Pearl, and Platinum. These names carried over to some characters in the manga.
    • Most Gym Leaders have names referencing their type specialty, so Rock-, and Steel-type Leaders fall into this as well: Brock, Jasmine, Roxanne (but not Roxie, who's a Poison-type Leader), Roark (similar to both "rock" and "ore"), Byron, Grant ("granite"), and Olivia ("olivine"note ). This could also extend to Ground-type Leaders Giovanni (referencing "geo,") and Clay.
    • Many rock/ground Pokémon named this way. Examples include Geodude, Graveller, Sandslash, Sandshrew, Regirock, Lunatone, Solrock.
    • As for Japanese names, from the fifth generation, there's Ishizumai and Iwaparesu. "Ishi" is "stone" and "Iwa" is "rock". Their English names are Dwebble and Crustle (as in Earth's crust- it literally carries a chunk of crust on its back!).
    • Pokémon Colosseum and XD have the Orre region, which is derived from "ore". Then there are the individual location names: Phenac City (phenacite), Pyrite Town, Agate Village, and Realgam Tower (realgar).

  • In Tales of the Abyss, we have Jade, his sister Nephry (Nephrite), and childhood friend Saphir (Sapphire). In a manga bonus chapter, Jade and Saphir are seen going to school with a young man named Jasper, all of which suggests that these kind of names may be somewhat traditional in Malkuth.
  • The Mogmas in The Legend of Zelda: Skyward Sword are all named after metals and ores, except for Tubert who's named after tuber, a type of plant part.
  • One of the female love interests in Story of Seasons (2014) is named Agate.
  • This may be at play in Dragon Age: Origins, but not overtly. The surname of the Dwarf Noble Warden is Aeducan, from the old dwarven word aeduc, which means either "shield" or "stone."
  • Super Robot Wars X: The last names of three of the Original Generation are Iolite, Aquamarine, and Obsidian. These are the names of crystals.
  • Dragon Quest XI's Kingdom of Heliodor (itself a form of beryl) contains several such characters, such as King Carnelian, Sir Jasper, and Princess Jade. The Odd Name Out is Sir Hendrick, who turns out to have been born somewhere else.
  • In WarioWare, areas around Diamond City have gemstone names like Sapphire / Emerald street, Agate forest, the Chromaconda rollercoaster, and Peridot campgrounds.

    Web Comics 
  • Karin-dou 4koma: Seren named Kinka and Ginka (coin youkai) after their coins' metal — gold and silver, respectively. At one point, Mifi wonders if the naming scheme would have continued if Tamaryu were a coin youkai instead of a dragon, with a name like "Douka" (corresponding to copper). Kinka and Ginka deem it very likely.
  • The Ménage à 3 spinoff Sticky Dilly Buns features sisters Amber and Ruby, hitting this trope and also Colourful Theme Naming.
  • In Monsterful the entire Gem family have literal jewel names, Sapphire, Ruby, Onyx, Topaz, Diamond and Pearl.

  • The Flintstones (as well as the Rubbles, Mr. Slate, Joe Rockhead, etc.). Hey, they are a modern stone-age family.
  • The Guatemala Clan in Gargoyles are named Zafiro, Turquesa, Obsidiana, and Jade. They're Spanish, but you can probably figure out what they mean.
  • On Trollz, almost all the characters have rock, mineral and/or gemstone-themed first names. To name some examples:
    • The BFFL (the main five characters) are named Amethyst, Ruby, Sapphire, Topaz and Onyx—their boyfriends are named Coal (for Amethyst), Rock (for Ruby), Alabaster (for Sapphire), Jasper (for Topaz) and Flint (for Onyx) and their main rivals are named Coral, Opal and Jade.
    • One possible exception to this trope is a minor character named Nicki—while not confirmed, it's possible that "Nicki" is short for "Nickeline," a type of mineral containing 43.9% nickel and 56.1% arsenic.
  • The Crystal Gems in Steven Universe are named Garnet, Amethyst and Pearl, with Steven's mother Rose Quartz being a former member. This extends to their entire race, and each has a gemstone which resembles their namesake and is their actual body.
  • In My Little Pony: Friendship Is Magic, rock farmers Igneous Rock and Cloudy Quartz have four children: Marble Pie, Limestone Pie, Maud Pie, and Pinkie Pienote .
  • Pearlie had a mild case of this, with the main characters being named Pearlie, Opal, Jasper, and Sapphira.

    Real Life 
  • A group of east-west streets running parallel to each other around downtown Albuquerque are named for various minerals. North to south, they are Copper Avenue, Gold Avenue, Silver Avenue, Lead Avenue, Coal Avenue, and Iron Avenue.
  • Philadelphia has a few clusters of streets named for precious or semiprecious stones. The most prominent is in Kensington and Port Richmond, where there's a series of streets running rougly parallel to Kensington Avenue called Jasper, Emerald, Coral, Amber, and Agate Streets.


How well does it match the trope?
