Caste System

“	This is what White Diamond expects of all of us...! From a thin flake of mica to the deepest, hardest stone, we all must make sacrifices for the sake of our perfect empire!	”
—Yellow Diamond, "Change Your Mind"

Prior to Era 3 the Gem Homeworld maintained a strict Caste System with gemstones having predetermined roles and places in the social pyramid and their own privileges and ordained purposes. Gems who deviated from this intentionally or not were considered defective. Since penalties were severe most disgruntled Homeworld Gems kept to themselves or went into hiding. Because there were so many of each Gem-type (except Diamonds) all Gems distinguished themselves via serial numbers. The Caste System was divided up under the rule of the Diamonds; if Gems were to greet or refer to others in a higher section of the Caste System they normally prefaced their Gem name with "My" to show they were their superior(s) (i.e. "My Diamond", "My Hessonite", etc).

As of the time between "Change Your Mind" and Steven Universe: The Movie and around Unleash the Light both it and the Gem Empire had been officially dismantled.

Rankings

Diamonds

Main article: The Great Diamond Authority

White Diamond.

Yellow Diamond.

Blue Diamond.

Pink Diamond.

Diamonds were the highest-ranked caste similar to royalty and referred to as the matriarchs of society; they still made up the Great Diamond Authority. All Diamonds were (mostly) massive towering over other Gems and most Fusion Gems seen. They all had diamond-shaped pupils in their eyes.

Most Homeworld Gems were fanatically loyal to them and appeared to be categorized under their respective Diamonds as Blue Diamond once referred to Sapphire as being "of [her] court" and Peridot 5XG said she was "made for" Yellow Diamond. Infidelity displayed towards the Diamonds was considered punishable by death at the worst. Their honorific was "My Diamond".

There appeared to be rankings within the Diamonds themselves as White Diamond was hierarchically superior to the other Diamonds and the leader of the Authority. Conversely Pink Diamond was below the other Diamonds and had to obey their orders.

Emeralds

Emerald.

Emeralds were high-ranking. In The Steven Universe Podcast Rebecca Sugar and Ian Jones-Quartey emphasized that Emeralds (specifically the one in "Lars of the Stars") were in charge of fleets. The only known Emerald had at least three ships (her personal shuttle, the Sun Incinerator and Destiny Destroyer) and held control over an unspecified amount of Gems.

Morganites

Morganites were high-ranking. While their exact roles remained unknown they were high enough to have their own Pearls and Rubies.

• Morganite - A Morganite mentioned by Rhodonite as having replaced her components after discovering they had fused.

Aquamarines

Main article: Aquamarines

Aquamarines were another type of high-ranking Gems. They appeared to serve as assistants to Diamonds using their own ships to travel from planet to planet and collect things they wanted. Rebecca Sugar said Aquamarines were high-ranked blue Gems.

Bixbites

Template:Bixbite

'''Bixbites''' were presumably high-ranking gems on homeworld, mainly due to being beryls in real life. They are known to have doll-like joints and are able to cut things perfectly.

=== Sapphires ===

Sapphire.

Padparadscha.

Sapphires were of the nobility class described as rare and part of the aristocratic elites; in spite of this they had no immunity from outcast status. They could see events using their future vision; Sapphires were the only normal Gems with this ability. Their honorific was "Your Clarity". Known subtypes included Padparadschas. They came in multiple colors despite the only varieties thus far being blue and orange as Garnet stated that Sapphires were a rare kind of Gem.

Garnets

Main article: Garnets

Garnets were commanders that aided in conquering and controlling planets. In some cases they were Light Prism-bearers and commanded entire colonies. Certain Garnets seemed to command different types of Gems but it is unknown if this was specifically applied or not. Subtypes included Hessonites, Demantoids and Pyropes.

The Fusion Gem of the same name had no relation as Blue Diamond was surprised to hear she called herself one in "Together Alone".

Hessonites

Hessonite.

Hessonites were a subtype of Garnets with orange coloring who served the military during colonization. They oversaw Quartzes such as Citrines as well as Nephrites and were more focused on strategies and battles.

Demantoids

Demantoid.

Demantoids were a subtype of Garnets with yellow-green coloring who served as overseers of the lower classes, worked on colony infrastructures and were more focused on technology.

Pyropes

Pyrope.

Pyropes were a subtype of Garnets with pink-red coloring who served as overseers of the upper class making up Homeworld's aristocracy once a colony was completed. Pyropes were noticeably fancier wearing gowns and living in places like the Palace of Light.

Lapis Lazulis

Main article: Lapis Lazulis

Lapis Lazuli.

Lapis Lazulis were extremely valuable to the Empire. As stated by Yellow Diamond in "What's the Use of Feeling (Blue)?" they were made for terraforming. Peridot 5XG also said they were typically partial to water and flying. Their use for terraforming planets likely explained one's ability to manipulate water with ease and possibly enjoying farming.

Jades

Main article: Jades

Jades appeared to be high-ranking given they attended the Era 3 Ball. Unlike most Gems they had differences between their physical appearances depending on which type of Jade they were though they have been seen in subtypes.

Nephrites

Main article: Nephrites

Nephrite aka the Centipeetle Mother.

Nephrites were in charge of piloting Homeworld Dropships and other spaceships and started building colonies. Their ranking was never clearly stated but appeared to be high considering they captained their own ships and Yellow Diamond contacted one directly in "Jungle Moon" which she would not do with low-ranking Gems. One Nephrite was a captain in charge of other Nephrites under Hessonite's command and leading a dropship that went to Earth.

Topazes

Main article: Topazes

Topazes seemed to be soldiers obeying orders and acting as bodyguards for assigned Gems; these were traits shared with Quartzes and Rubies. Topazes also acted as guards of places suitable for more elite Gems as seen in "Familiar". Rebecca Sugar said Topazes were high-ranking yellow Gems (although oddly enough, Topaz is not exclusively yellow).

Zircons

The defending Blue Zircon.

The prosecuting Yellow Zircon.

Zircons acted as lawyers though they had no choice over what cases they prosecuted or defended for as revealed in "The Trial" and were assigned them instead. In the podcast Rebecca Sugar and Ian Jones-Quartey said they had a sort of medium rank serving the upper classes but no individual power.

Peridots

Main article: Peridots

Peridot 5XG.

Squaridot.

Peridots served as technicians and Kindergarteners sometimes performing field assignments on other planets such as Peridot 5XG. Being workers they had a low ranking and were only allowed into elite Homeworld areas if a job was needed to be done there.

In Era 2 Peridots were given Limb Enhancers to compensate for the lack of strength and unique abilities older Gems had due to the depletion of resources on Homeworld. Despite this Peridot 5XG was shown to have ferrokinetic abilities.

Quartzes

Main article: Quartzes

Quartzes, like Topazes and Rubies were soldiers. Made to fit the roles of elite warriors Quartzes normally had incredible height, broad shoulders and an intimidating muscular build. Jasper fit this description but Amethyst did not because she "stayed in the ground too long" and was therefore "overcooked". Some were used as bodyguards and escorts as shown in Jasper's case. They appeared to be less numerous than Rubies though greater than Topazes. According to Ian Jones-Quartey some had defensive powers as well like Rose Quartz since "they can't all be tanks". Quartzes were described as being "huge, loyal soldiers". Jasper stated Quartzes were made to fight and her kind specifically always got what they wanted. Some also acted as elite guards at Homeworld outposts such as Pink Diamond's Zoo or like the Quartzes commanded by Emerald and Hessonite. They were Gems commonly made on Earth and the most diverse known Gem-type with subtypes including Agates, Amethysts, Carnelians, Citrines, Jaspers and Rose Quartzes.

Agates

Holly Blue Agate.

Blue Lace Agate.

Crazy Lace Agate 1

Crazy Lace Agate 2

Agates seemed to take on administrative roles as higher ranking Gems. Yellow Diamond stated in "What's the Use of Feeling (Blue)?" they were meant to be terrifying figures intimidating Gems under them into obedience. In "The Trial" it was revealed they could also be bodyguards. It could be assumed based on the way Holly Blue Agate acted around Sapphire and the Diamonds that while having some authority Agates were not high-ranking compared to Sapphires.

Citrines

Citrines were a subtype of Quartzes appearing to be elite guards that serve high-ranking Gems.

Rose Quartzes

Rose Quartzes were new compared to other Gems having been created on Earth. Sometime between the start of one's rebellion and Pink Diamond's shattering every Rose Quartz in existence was bubbled and made to reside in Pink Diamond's Chamber in her Zoo. It was stated in "That Will Be All" that Blue Diamond wished to keep them around for the sake of preserving Pink Diamond's legacy while Yellow Diamond wanted them shattered as they believed one to be responsible for the start of the Rebellion and Pink Diamond's destruction although this was not really the case. While still being soldiers they were apparently known for defensive powers rather than the offensive abilities other Quartzes had although this may be exclusive to the Rose Quartz who was actually Pink Diamond and not the cut of Gem as a whole. Their gemstones appeared to be modeled after the table facet of Pink Diamond's own gemstone lacking the pavilion and instead having a mirrored back.

Cherry Quartzes

Cherry Quartz.

Cherry Quartzes were a subtype of Quartzes with pink coloring. Based on other Quartzes it could be assumed they were Gems of the soldier type as well.

Amethysts

Amethyst.

A red Amethyst with a unique cut.

The red Amethyst with the usual cut although it appears less making it unclear which is correct.

Lace Amethyst.

Amethysts were a subtype of Quartzes mostly with purple coloring. The Prime Kindergarten on Earth produced Gems of this type. Amethysts acted as soldiers and/or guards as seen with the Amethysts guarding Pink Diamond's zoo.

Carnelians

Carnelian.

Carnelians were a subtype of Quartzes with maroon-red coloring. The Beta Kindergarten on Earth produces Gems of this type. Based on other Quartzes it could be assumed they were Gems of the soldier type as well.

Jaspers

Jasper.

Skinny Jasper.

Ocean Jasper

Biggs Jasper.

Zebra Jasper

Eyeball Jasper.

Jaspers were a subtype of Quartzes mostly shown to have tangerine skin and red-orange markings though some were different colors, shapes and sizes depending on the kind of Jasper they were. Similar to other Quartzes below Agates they acted as either soldiers or guards.

Tiger's Eyes

Tiger's Eyes were a subtype of Quartzes yet to be seen but mentioned by name.

Angel Aura Quartzes

Angel Aura Quartzes were multicolored Quartzes.

Unnamed Quartzes

The unnamed type of Quartz that appears in "The Phantom Fable".

Bismuths

Main article: Bismuths

Bismuth.

Bismuths were builders for aristocratic members of society. As such they possessed a broad stature for intense physical labor, above-average resistance to heat and damage and hands capable of fluidly changing form without the need for typical Gem shapeshifting to fit a wide variety of purposes.

Obsidians

Snowflake Obsidian.

Obsidians were tall Gems with a muscular upper half. Like Bismuths, Obsidians were a lower level labour gem, who dug out trenches for Homeworlds armies to use. Unlike Garnets which shared similarities regardless of being Fusion Gems or not Snowflake shared no physical characteristics with the Fusion Gem of the same base name.

• Snowflake Obsidian - A formerly corrupted member of the Crystal Gems who used to dig out ice trenches in the snow when she served Hoemworld.

Larimars

Little Larimar.

Larimars served as sculptors for the Diamonds and other elite gems, although it is unclear if this gave them a high rank in the cast or if they were considered lower class gems.

• Larimar - A formerly corrupted member of the Crystal Gems who used to use her ice powers to create ice sculptures for the Diamonds while she was on Homeworld.

Rubies

Main article: Rubies

Rubies were another soldier caste and nearly the lowest-ranked of all Gems. They also filled the roles of escorts and bodyguards as well as scouts. Due to their numbers individual Rubies were considered expendable footsoldiers or cannon fodder and much of their worth came from fusing with each other.

Rubies had almost no differences in appearance and were not supposed to have different personalities; the fact they did "flies under the radar" because they mostly acted serious around high-ranking Gems.

Spinels

Spinel.

Spinels were entertainers for those designated their "best friend". They were implied to be rare as Pearl stated in "system/BOOT.pearl final(3).Info" that Steven was a "lucky one" for acquiring such a Gem. The body of the only one seen was more elastic than other Gems even going beyond the movements of Bismuth. According to Rebecca Sugar their gemstone cuts were shaped like playing card suits (hearts, clubs, spades and diamonds).

Pearls

Main article: Pearls

Pearl.

Yellow Pearl.

Blue Pearl.

Pink Pearl.

Lonely Pearl.

Pearls were a servant caste and had such a low rank they were not even considered real Gems but instead viewed as property. They were expected only to serve and be submissive and obedient simply waiting on their owners until being told "That will be all" and not acting independently in any way. Pearls also provided simple luxuries like singing, dancing and entertainment by projecting holograms.

Unlike other Gems Pearls did not have a set uniform as they could be customized in colors and appearances. The position of a Pearl's gemstone along with their colors was made to match their owners with the exception of Pearl likely because she was Pink Diamond's replacement Pearl as opposed to her original one whose features did match her owner.

Pebbles

Main article: Pebbles

Pebbles also acted as servants but unlike Pearls who belonged to individual Gems they appeared to serve everyone. They had building and sewing skills that were enough to fulfill different tasks at incredible speed.

Other Roles

Fusion Gems

Main article: Fusion Gems

Fusion Gems, Gem Fusions or just Fusions, specifically Same-Gem Fusions were used as weapons, especially in times of war and solely for combat being seen as objects rather than their own beings. Fusions outside of battle were considered inappropriate and unorthodox regarded as disgusting, embarrassing or discomforting to behold as inferred from Jasper and Peridot 5XG's reactions towards Garnet. However, the existence of Topaz revealed that despite this, fusions outside of battle were indeed legal on Homeworld provided they were of the Same-Gem type and could only be allowed for certain castes (e.g. soldiers). Even then they were still looked down upon for having a capacity of sentimentality as revealed by Aquamarine.

To a further extent only Fusions of the same type were seen as acceptable such as Fusions consisting of Rubies or Topazes. Fusions between Gems of different varieties were considered abnormalities as the Gems of Blue Diamond's court referred to Garnet as "disgusting" and "unheard of". As other examples Rhodonite and Fluorite were forced to hide to avoid being shattered; Rhodonite's components were even replaced by their Morganite after she found out they liked to fuse. The reasoning for prejudice against Different-Gem Fusions was because they created an entirely new Gem which disrupted Homeworld's society; the new Gem could've had no place in the Caste System and thus hold no job beneficial to Homeworld.

Gem Shards

Main article: Gem Shards

Gem Shards or Shards were the remains of Gems shattered mostly for rebelling against the Caste System. However, according to Pearl in "Frybo" they still had "a powerful partial consciousness that has been harnessed by Gems throughout history to create semi-sentient drone soldiers with the capacity to follow basic orders"; like intact gemstones they could even be used as power sources as seen in "Friend Ship". Unfortunately this proved dangerous to the point Shards in any containers ended up attacking everything around them; in some cases they regenerated as disembodied limbs that would seek out the missing parts of themselves in hopes of reuniting with them.

Unspecified Types/Roles

Main article: Unknown Gems

Main article: Minor Characters/Gems

Gems lacking known Gem-types or societal roles. These types of Gems have been seen in full but their places in the Caste System have not been alluded to enough to determine their positions.

Spodumenes

Orange Spodumene aka the Worm Monster.

Spodumenes were Gems with large singular eyes sometimes covered by hair. They have only been seen in orange coloring although spodumene comes in many colors in the real world.

Green Dwarf Gems

The Heaven Beetle and Earth Beetle.

This type of Gem had varying shades of green ranging from bright lime-yellow to pale forest-green. They are small in stature compared to Aquamarines.

Tourmalines

Tourmalines were large and bulky Gems with balloon features.

Watermelon Tourmalines

Watermelon Tourmaline.

Watermelon Tourmalines were a subtype of Tourmalines with pink and green coloring.

Violet Gems

The Water Bear.

Very little was known about this type of Gem. They appeared to have a hunched stout build and the only instance shown had her body shrouded in a gelatinous cloak revealing very little about her physical features.

Rutiles

The Rutile Twins' intersected gemstone.

Rutiles were tall and lanky Gems with a somewhat rectangular build resembling a real-life rutile. Although not much was known about them they seemed to have piloting capabilities. Judging by the words of the Rutile Twins they appeared to be mass-produced thus likely holding a low rank although this is unconfirmed.

Other Unknown Roles/Gem-Types

Desert Glass.

Comby.

• Desert Glass - A presumably uncorrupted Gem seen in "Steven's Lion" with the ability to create structures out of sand. Her physical form has not been seen. The type classification which this Gem falls into is unclear.
• Beryls - Nothing is known about this type of Gem although one was a Crystal Gem during the Rebellion. Despite sharing a real-world mineral class with Aquamarines and Emeralds they appeared to be unrelated.
• Serpentines - Nothing was known about this type of Gem although one was a Crystal Gem during the Rebellion.
• Pyrites - In "Familiar" Blue Diamond mentioned she let Pink Diamond name a batch of Pyrites as Fool's Gold. They may be high-ranking due to a small batch seemingly being regarded as a specialty.
• Comby - A Gem in the shape of a comb who serves Blue Diamond. She resembled a Pebble and it was very likely she was one.
• Kyanites - In "Change Your Mind" Blue Diamond mentioned she let Pink Diamond bring alien worms to Homeworld from a colony of Kyanites.
• Micas - A type of Gem mentioned by Yellow Diamond in "Change Your Mind".
• Stones - Another type of Gem mentioned by Yellow Diamond in "Change Your Mind".

Defective Gems

Main article: Off Colors (group)

Main article: Crystal Gems

Defective Gems referred to as being Off-Color served no use to the Empire, were cast out of its society and if caught were shattered. The only exceptions were the Quartzes at Pink Diamond's Zoo kept in service by Blue Diamond. Amethyst was another exception provided she wore Limb Enhancers like Era 2 Gems to reach her "height requirement".

Corrupted Gems

Main article: Corrupted Gems

Corrupted Gems, also known as Gem Monsters were Gems who became corrupted by the Diamonds after the Rebellion assuming monstrous and nigh-incoherent forms. One of the main objectives of the Crystal Gems other than the protection of humanity and Earth was to defeat, contain and hopefully cure these Gems. They did not exist on Homeworld and as such had no place in its society.

Mutant/Cluster Gems

Main article: Cluster Gems

Main article: The Cluster

Cluster Gems, otherwise known as Gem Mutants were Crystal Gems shattered during the Rebellion and fused against their will into monsters similar to Corrupted Gems. The Cluster was a result of the Diamonds attempting to harness this process to create a "geo-weapon" which would destroy Earth and other planets as well.

Trivia

• This utilitarianism or functionalism-inspired governing system of judging an individual's worth on their outward appearances was similar to the Caste System and Functionism from Transformers, specifically the Aligned series and 2005 IDW Generation One reboot in that they were glaringly suppressive, toxic, flawed and resulted in uprisings that brought about the end of times during which many lived in fear for their lives should they step out of line.
• The movie revealed that Rejuvenators were the initial method of wiping out disobedient Gems, but due to those Gems being able to restore their memories from something that influenced them the most, this was ended in favor of either imprisoning or shattering them.
