The Gem Homeworld, or simply Homeworld, is the home planet of the Gem race and presumed capital of the Gems' intergalactic empire. It was initially mentioned in "Mirror Gem", and officially debuted in "The Trial".
Before "Change Your Mind"
Little is known about the Gem Homeworld and its previous history, culture, and society. What is known, however, is that Homeworld used to be a totalitarian, oligarchical society governed by the Great Diamond Authority. In this society, the Diamonds ruled over Gemkind, which consisted of a variety of Gems, each assigned a different role based on their Gem-type according to the Caste System that was implemented. For instance, Pearls were servants and considered to be lower-ranking Gems, while the Diamonds were the highest-ranking Gems. The higher up on the Caste System a Gem was, the more privileges and responsibilities they had. Deviation from a Gems' given purpose resulted in punishment, which could sometimes escalate to shattering (the destruction of a Gem). The goal of the Gem race was to expand the Diamonds' "perfection" across the universe by traveling to other planets and establishing colonies. As noted in "It Could've Been Great", once suitable planets were located, they were exploited through facilities known as Kindergartens (which drains a planet's resources to create new Gems) and are terraformed to be made fit for Gem settlements. Any organic life living on a colonized planet would be killed since the process of creating new Gems completely strips a planet of its lifeforce, making the world unsuitable for new life to form. Once a colony is completely drained of its resources, they were typically abandoned and left as husks of their former selves.In "Log Date 7 15 2", Garnet mentioned that the Gem Homeworld is not located in the Milky Way Galaxy, where Earth resides, but in a separate galaxy still visible from Earth.
Homeworld is also technologically advanced, achieving intergalactic travel thousands of years before the beginning of the events of the series. According to Lapis Lazuli, it had become even more advanced since the Rebellion to the point of being unrecognizable when compared with the time that Lapis left, now possessing further technological achievements such as the Gem Warship and Gem Destabilizers. This advanced technology greatly contrasts the old and decrepit Gem technology left on Earth, which Peridot considers to be archaic.
Homeworld in its entirety was shown for the first time in "Legs From Here to Homeworld", where the planet is shown to be a shattered ringworld. Two sets of dark blue rings surround the planet, where its rocky chunks are still held relatively close together by gravity. The surface of the chunks themselves is where the Gem Empire resides, mostly white with small shades of other colors such as pink, blue and yellow mixed in as well. It is currently unknown what kind of catastrophic event has caused the planet to be shattered to the degree shown. The glossy surface of the planet is the dense cityscape carved into its natural surface. The planet has a pink-colored atmosphere breathable by humans, and a similar level of gravity to that of Earth.
Above the planet's surface are layers of dense, artificial infrastructure. The architecture is geometrical, with many of the buildings taking the forms of crystalline structures or inverted pyramids. The sides of many buildings are dotted with dark, neatly-arranged holes. Translucent tubes connect many of the buildings, entering through these holes. Flashes of colored light can be seen traveling along the tubes, although their purpose is unknown. Deep, dark pits lead down into the planet's abandoned surface.
The actual surface of Homeworld is dead, wasted, and abandoned, presumably from the Kindergartens draining the planet's natural nutrients. Dotted around the planet's surface are abandoned Gem structures. Some of the abandoned structures include ancient obelisks resembling the newer ones placed on the upper levels. The old broken statues left behind appear to be fusions, implying that when the original surface began to die Homeworld Gems began to expand upwards, leaving old buildings and some aspects of their culture behind.
Homeworld was a warlike, inhumane society bent on spreading Gems across the universe at any cost, including wiping out organic life. They simply did not care about non-Gem life forms, seeing them as inferior. The Gems came to Earth for the reasons of building a colony and later destroying it after the Rebellion.
After the events of "Change Your Mind", the Diamonds realized the error of their ways thanks to Steven, and completely dismantled Gem society. Realizing that their previous ways of ruling Gemkind were immoral, the Diamonds first disposed of the Caste System so that all Gems are equal; any Gem is free to live the life they want without fear of persecution and punishment. Next, the Diamonds dismantled their armies and ceased colonization of other planets. Finally, Gems are now free to live wherever they please in the universe; Homeworld, Gem colonies, Earth, or anywhere else. Although the Diamonds are still the leaders of the Gem race, they are much more lenient with their ruling and now wish to spread peace and love across space.

"Mirror Gem"/"Ocean Gem"
Lapis Lazuli desired to return "home", referring to the Gem Homeworld. It can be seen that the Gem Homeworld is within a great distance from Earth and that Lapis Lazuli leaves Earth and travels in the direction of these stars to the Gem Homeworld. The stars are similar to what may be a map on the Galaxy Warp.
The Gem Homeworld is mentioned by name, and Peridot warps to Earth from there. The Homeworld Warp Pad is repaired by her Flask Robonoids for Peridot to perform a maintenance check. Upon her departure, Garnet destroys the Warp Pad with her gauntlets, once again preventing travel to and from Homeworld.
Amethyst reveals that the Homeworld Gems created other Gems in a facility known as a Kindergarten. Amethyst, among many other Gems, is one of these creations.
According to Peridot, Homeworld has records containing information. These records state that Gems were wiped out on Earth, which is what Homeworld presumed when the Corrupting Light went off.
Lapis Lazuli states that Homeworld is much more advanced, and she does not understand any of it. She contacted the Gems with technology that could communicate with the Wailing Stone, but only with help from Greg.
"The Return"/"Jail Break"
The Gem Warship, transporting Jasper, Peridot, and Lapis Lazuli, is dispatched to Earth from Homeworld. It is supposed to return to Homeworld, but it crashes back to Earth.
Peridot had attempted to repair the Homeworld Warp again, successfully collecting all the pieces of the Warp Pad. Unfortunately, without her Flask Robonoids, she was unable to repair it completely. Peridot is then defeated and temporarily bubbled by the Crystal Gems until Steven unbubbles her in an attempt to find out more about Peridot's real mission on Earth. It is later revealed by Peridot that she was sent on a mission from Homeward to Earth to report progress on the emergence of the Cluster.
Peridot reveals that it does not rain on the Gem Homeworld. According to her, Homeworld eventually no longer saw the Earth as a viable colony and decided to use it for experimentation, apparently several centuries ago. One such experiment is the Cluster, composed of millions of Gem Shards. At this point, it is currently residing in the Earth's core.
Peridot mentions Homeworld when she explains that Pearls such as Pearl herself are servants there.
Garnet mentions that Homeworld sent numerous diplomats to Earth, and it is revealed that there is another authority figure called Blue Diamond.
While on the moon retrieving vital information on the Cluster, Peridot explains that Gem physiology is designed for the express purpose of aiding Homeworld's interstellar conquering. Later, she reveals Homeworld's original plan for terraforming the Earth.
Peridot manages to contact Homeworld through a Diamond Communicator from the Gem Moon Base, and Yellow Diamond's base, presumably somewhere on or near Homeworld, is seen during her conversation with Peridot about sparing the Earth from the Cluster.
Garnet points out Homeworld in the night sky and reveals that it is in another galaxy of its own, instead of the Milky Way.
Lapis Lazuli tells Steven about how she was caught in the middle of the Rebellion. She was poofed, picked up by a Homeworld soldier, and mistaken for a Crystal Gem. Homeworld forces placed Lapis into a mirror and asked her where the Crystal Gems' base and their leader was, but Lapis did not have the answers. When the Rebellion could not be stopped, Homeworld fled Earth and left Lapis behind on Earth.
The Rubies sent to Earth from Homeworld reveal that they were sent by Yellow Diamond to find Jasper (who is the head of the "failed" Earth mission to escort Peridot).
Peridot tells Steven and Amethyst that Homeworld's resources are depleting and newer generation (Era 2) Peridots lack basic powers and abilities. This may or may not limit newer generation Gems to have weapons or even fuse.
It is revealed that Nephrite was the captain of a squadron sent from Homeworld to Earth during the Rebellion in an Ancient Gem Colony Ship, alongside her crew, by an unknown Gem commander.
Garnet tells Bismuth that the Gems on Homeworld outnumber the Crystal Gems by a huge amount. Bismuth reveals to Steven that Homeworld used Bismuths to "erect spires and temples for the Gem elites to enjoy". She also tells Steven that Bismuths were used to build arenas and spires were used for philosophers to think in.
Peridot reveals to Steven and Amethyst that Homeworld struggled to generate extra soldiers to compete with Rose's army halfway during the Rebellion, so they created the Beta Kindergarten: a rushed Kindergarten used to get soldiers on the ground quickly.
Jasper tells a Corrupted Gem that her weakness is what embarrasses Homeworld. She also tells Steven, Peridot, and Amethyst that every Gem is made to serve the Great Diamond Authority. Those who do not serve the Diamonds are to be shattered and is considered a disgraceful act.
The Rubies reveal that Homeworld Gems have to write up reports after completing missions, hinted at by Peridot when she had her Limb Enhancers.
"Eyeball" tells Steven that she heard rumors that there could still be Crystal Gems (including Rose Quartz) on Earth. These rumors could have possibly originated on Homeworld.
Peridot reveals that there are no Corrupted Gems on Homeworld.
Through the whole episode, Steven is put on trial by the Diamonds for the crimes of Rose Quartz, when the defending Zircon discovers that the rumors of Pink Diamond's shattering do not make much sense or match with the crime, she accuses the Diamonds as potential suspects. After Yellow and Blue Diamond start arguing when the former poofed both Zircons, Steven and Lars escape by stealing Blue Diamond's palanquin.
Lars and Steven flee from a Shattering Robonoid until they encounter the Rutile Twins, who help them find their way through an abandoned Homeworld Kindergarten and meet the other Off Colors: Padparadscha, Rhodonite, and Fluorite. The group explains that defective Gems are not accepted in Homeworld society and consequently shattered. After Lars dies defending the Off Colors from some Shattering Robonoids, he is revived by Steven's healing powers.
After bringing Lars back to life, Steven discovers that Lars' hair now works as a portal to Earth by virtue of being connected to Lion's Dimension. When Lars proposes Steven and the Off Colors go to Earth while he stays behind, the Off Colors refuse because they do not want to leave Lars alone. Lars insists Steven return, however, eventually convincing him to reluctantly go back home to Earth.
Steven tells Connie about his experience on Homeworld, such as being put on trial and chased alongside Lars by robonoids.
Greg assumes that what is upsetting Steven is something that happened on Homeworld that Greg would not understand, so he convinces Garnet, Amethyst, and Pearl to talk to Steven and try to make him feel better.
Steven tells Peridot and Lapis about his trip to Homeworld. When he mentions that he fled the Diamonds, Lapis panics and prepares to leave Earth.
Lars tells Steven how he and the rest of the Off Colors escaped from the planet.
Blue Diamond tells Steven about how he escaped Homeworld and crawled back to his home planet, Earth.
The Crystal Gems (minus Bismuth, Peridot, and Lapis Lazuli), along with the Diamonds, travel to Homeworld to discuss the cure to corruption with White Diamond.
Steven explores various locations on Homeworld such as Blue's pool and Yellow Diamond's extraction chambers.
Steven and the other Diamonds prepare the Era 3 Ball to celebrate Pink Diamond's return and to begin discussions with White Diamond. At the end of the episode, Stevonnie is thrown into the Prison Tower.
Steven uses his mind powers to get help from the other Crystal Gems while still stuck in the Prison Tower.
"Change Your Mind"
Steven manages to escape the Prison Tower and fight the Diamond Mech and White Diamond in the heart of Homeworld's city.
Steven Universe: The Movie
Homeworld is shown at the start of the movie when White, Blue, and Yellow try to convince Steven to stay there in the palace with them.
White Diamond's ship is surrounded by colorful structures; the atmosphere is pinkish white, as opposed to the usual night sky with stars last seen in "Steven Universe: The Movie" and Blue and Yellow Diamond's ship are nowhere to be seen, but when they travel to the Earth on "I Am My Monster" they can be seen. White's Ship is in front of the warp pad that Steven arrives in, situated in the pink section of the big diamond emblem that Homeworld Gems were standing in when the Crystal Gems; accompanied by Yellow and Blue Diamond, arrived at Homeworld in "Legs From Here To Homeworld". The Throne Room is now used for display, and the three diamonds now have their own rooms, dedicated majorly to their new abilities.
Homeworld used to maintain a strict caste system, with each type of gemstone having a predetermined role and place in the social pyramid, each with their privileges and ordained purposes. Any Gem who, in any way, digresses from their role, be it intentional or not, would be considered defective. Since the penalties for such actions are severe, most disgruntled Homeworld Gems either keep their dissension to themselves or were forced to go into hiding. Because there are so many of one type of Gem, the Homeworld Gems — except the Diamonds — distinguished themselves via coded serial numbers.
- Main article: Caste System
Resources are dwindling on Homeworld. They can't make Gems like they used to. That's why they give Era 2 Peridots technological enhancements. Because we... don't have powers.
|—Peridot, "Too Short to Ride"|
Things labeled as "Era 1" were created before the alleged shattering of Pink Diamond. During this period, resources were abundant on Homeworld and the Diamonds expanded their Empire across the galaxy. Some examples of Era 1 artifacts are the majority of the Gem structures on Earth, and the Ancient Gem Colony Ship. Era 1 Gems possess all standard Gem abilities. Joe Johnston also points out that Era 1 architecture is based on Art Deco with Roman columns.
Era 2 began with the alleged shattering of Pink Diamond. At some point in time after the Rebellion, Homeworld began running low on resources. To compensate, Homeworld Gems manufactured Gems with fewer abilities to continue Gem production on Homeworld. Some Era 2 Gems are given technological enhancements to make up for their inferior nature. Era 2 ships, such as the Roaming Eye, are known to be more advanced than Era 1 ships. Peridot is an example of an Era 2 Gem. The Ruby known as "Leggy" is quite young and could be presumed as Era 2. Era 2 is more rigid, sleek, and controlled, with its postmodern aesthetic.
Era 3 began with the return of "Pink Diamond" (Steven) to Homeworld after roughly 6,000 years. The beginning of Era 3 was celebrated with a large ball (in "Together Alone"). After the events of "Change Your Mind", Era 3 continued with the cure of Gem corruption on Earth, the dissolution of Homeworld's armies, and the liberation of existing colony worlds, all due to Steven's influence over the other Diamonds' way of thinking. The Diamonds gave up their power and introduced democratic elections in their stead.
There are occupations on Homeworld which were filled by one or more types of Gems in accordance with the strict caste system. However, since the caste system has been dismantled these occupations can presumably now be filled by any Gem. They include but are not limited to:
Steven, Homeworld is not the way it used to be. Everything here is so advanced! I can't even understand it! There's no way anything on Earth can stand up to it! Please, don't put up a fight, it'll only lead to devastation!
|—Lapis Lazuli, "The Message"|
In contrast to earlier Gem technology, which is notably rock- and light-based, some recent Homeworld innovations have seemingly electrical and plastic components, such as destabilizers or robonoids.
- Anti-Gravity Technology
- Faster-Than-Light Communication Technology
- Destabilizer Weapons
- Escape Pods
- Hourglass of Time
- Limb Enhancers
- Red Eye sentries
- Replicator Wand
- Space Stations
- Tracking Vessels
- Tractor Beam Wands
- Transport Ships
- Warp Pads
- Warships (equipped with powerful beam weapons and destabilizer containment fields)
Judicial courts in Homeworld use a system similar to a hybrid of the adversarial and inquisitorial court systems, the main amalgamations being an inquisitorial cast of impartial individuals with no jury and an adversarial court proceeding. The accused is assigned an attorney to convince the Diamonds of negating further charges or the charge entirely. The accusing party, called the plaintiff, assigns a prosecutor to present the case against the accused and convict the defendant.
The court also contains a court reporter that transcribes everything that occurs in the courtroom and a court sketch artist to depict proceedings inside the courtroom. After hearing both sides' cases, the judges decide whether the defendant is innocent or guilty and, if they are guilty, how and what will be the appropriate charge or sentence.
The only case seen so far was when Steven (posing as Rose Quartz) was tried in front of Yellow Diamond and Blue Diamond, acting as both judges and plaintiffs, with a Zircon being Steven's defense lawyer and another Zircon as the prosecutor of the case. Both of the Diamond's Pearls are also present, Yellow Pearl acting as the court reporter and Blue Pearl as the court sketch artist.
Previous Rules and Taboos
All Gems were expected to follow the rules enforced by the Great Diamond Authority. Depending on the severity of a broken rule, a Gem could've faced a number of punishments.
A Gem Must Remain in Their Caste
Every Gem had a purpose in Homeworld's society. Some were scientists, some were pilots, but regardless, a Gem must perform the duties they were made for. A Gem straying away from their purpose, such as a soldier creating art, would've resulted in punishment.
Fusion only had one purpose in Homeworld society, and that was to be used as weapons during times of conflict, otherwise, their existence would be considered purposeless and useless. Fusion, however, could only occur between the same types of Gems, such as two or more Rubies. Cross-Gem fusions, such as a Ruby and a Sapphire, were considered disgraceful and always resulted in a punishment. This was to prevent two Gems of lower caste from fusing into a higher-ranking Gem.
Similar to Fusion, shapeshifting was only to be allowed if it was to aid the Gem into fulfilling her purpose, such as a builder shapeshifting her hands into construction tools. Gems reshaping themselves outside their respective purpose was considered an insult to the Gem's intended form.
Every Gem is made with a purpose: To serve the Order of the Diamonds. Those who cannot fit inside this order must be purged! To come out misshapen, to reshape yourself outside your purpose, and to defend this ruined, worthless planet is a disgrace!
- Execution (Shattering) – Formerly the most common punishment, which involved the shattering of the gemstone, eliminating the core of the Gem and the Gem themselves. Rose confided to Pearl that losing the war would end in them being shattered by the Diamonds. Ruby was sentenced to be broken by Blue Diamond for accidentally fusing with Sapphire, shortly before the latter rescued her soon-to-be former guard, and Yellow Diamond proposed (on deaf ears) to shatter every Rose Quartz Gem because of the actions of Rose Quartz for shattering Pink Diamond.
- Forced Fusion* – As theorized by Garnet, the Gem Mutants were created as a punishment to the fallen rebels for siding with Rose Quartz and the Crystal Gems during the war for Earth. However,as seen in Yellow Diamond's bubble chamber, they seem to be experimental and not entirely made to suffer.
- Rejuvenation* – According to Bismuth, Homeworld's Authorities used to use The Gem Rejuvenator to reset Gems that were seen to have defected. Also, Pearls whose considered defective and could not be repaired/healed by Shell were restrained and reset in The Reef. However, it does not seem to be in the vein of punishment; rather, a discarded means of restoring the offender to do their job like before, though Rejuvenation can be undone, leading to the practice being fairly unknown to Gems in Era 2 that would have no need/status for a Pearl.
- Bubbling* – The Diamonds used to have every Rose Quartz Gem bubbled and placed in Pink Diamond's Zoo until Era 3, both in memory of Pink Diamond and for being the Gem type that Rose Quartz was, who allegedly assassinated Pink Diamond. Certain gems, presumed to be forced fusions, are bubbled in Yellow Diamond's bubble chamber, letting on that even Homeworld uses bubbling as a humane alternative to other means of reuse.
- Harvesting – This presumably involves the recovery and containment of the offender's gemstone to be used for some unknown purpose. Peridot assumed this would happen to her when she saw the Gem Bubbles in the Burning Room. The name suggests that defective (even beyond the standards of Era 2) Gems would be recycled for resources long since depleted.
- Conscious incarceration – During the Rebellion, Homeworld forces recovered Lapis' gemstone and placed it in a mirror in an attempt to gather intelligence on the Crystal Gems from her, confusing her for one of them. In addition, the useful containment of Gem Shards seemed to share a concept- however, the latter had more control over their prisons, leading to revolt.
- Corruption – Corruption was indirectly used as a punishment against the Crystal Gems, and all other Gems present on Earth, from a blast created by White, Yellow, and Blue Diamond. However, as evidenced by the reactions of Blue and Yellow, this was an accident; the intention was a mass shattering. Certain means prevented damage- though very few gems survived such a widespread phenomenon.
On numerous occasions, it has been stated that Homeworld has records cataloging different events in Gem history and facts about locations. It is unknown if reports that Gems must complete after missions are also cataloged in these records.
The records are known to contain hundreds of years of reports cataloging the Rebellion which Peridot has read up on. The Defending Zircon says that records state Pink Diamond was shattered by Rose Quartz in front of her entire entourage. In addition, the records state that Pink Diamond was shattered outside of her own palanquin. Witnesses stated that Pink Diamond stepped out of her palanquin when Rose suddenly attacked her from the front. The records also state that all Gems were wiped out on Earth, according to Peridot. During "The Trial", Yellow Pearl writes down every event that takes place and tells Steven to state his name for the records.

- Homeworld invaded Earth and established the Kindergarten about 6,000 years prior to the events of the show, but was driven off by the Crystal Gems' war of rebellion 5,000 years ago. Based on the numbers given, they occupied Earth for at least a thousand years.
- It is unknown if the planet has an actual name, as up to this point it has only been referred to as "Homeworld".
- Pearl said that Earth was not a Gem-controlled planet, possibly inferring that some planets are under Gem occupation.
- Later, in "Cry for Help", Peridot states that Earth is a part of the "Crystal System", suggesting that Homeworld has incorporated its colonized worlds into a larger territorial body, and has categories for the star and solar systems.
- Interestingly, "Crystal Systems" are the classifications of gemstone structures, of which there are seven, each having characteristic shapes. The systems differ regarding the angles between faces and in some edges of equal length on each face.
- In "It Could've Been Great", Peridot reveals that Homeworld is an imperialistic society, with several planets under their control.
- Later, in "Cry for Help", Peridot states that Earth is a part of the "Crystal System", suggesting that Homeworld has incorporated its colonized worlds into a larger territorial body, and has categories for the star and solar systems.
- It was first implied by Garnet in her verse of the extended theme that living as a fusion on Homeworld may be a practice that is looked down upon, which could be the reason why she willingly sided with the Crystal Gems in the Rebellion.
- This is supported by Jasper's comments on Garnet during both "The Return" and "Jail Break".
- Peridot also supported this theory by calling Garnet a "filthy war machine", implying that fusions on Homeworld are primarily used for war.
- It is proven true in "The Answer" by how the members of Blue Diamond's court reacted to Ruby and Sapphire fusing for the first time, finding the fusion between two different Gems abhorrent.
- This factor was again stated in "Off Colors" by Rhodonite when she was replaced by her unknown master, Morganite.
- It is revealed in "When It Rains" that it does not rain on Homeworld since Peridot was not familiar with the phenomenon. This, along with Gems' non-organic physiology, may be indicative that Homeworld does not have an atmosphere.
- However, this may not be the case since Lars has no problem breathing in "The Trial" and "Off Colors".
- Pearl reveals that Homeworld does, indeed, have an atmosphere in "Legs From Here to Homeworld".
- As revealed in "Familiar", Homeworld has a day and night cycle.
- Peridot reveals in "Back to the Barn" that Homeworld is a caste society.
- A Peridot with a Pearl servant is unheard of on Homeworld since Pearls are considered a luxury for higher classes like the Diamonds, as seen in "The Answer".
- Peridot's lack of knowledge on the wheel hints that Homeworld's advancement has reached far enough that the wheel has become technologically obsolete and has passed out of use and general knowledge.
- In "Too Far", Peridot is unfamiliar with the 24-hour terrestrial day and refers to it as a "rotation". However, she is familiar with the concepts of years, centuries, and eras. The exact specifics of Homeworld chronology remain unclear.
- Gems refer to their designated Diamonds as "My Diamond".
- As seen in "Message Received", Gems salute their Diamonds and other superiors by crossing their arms and forming a diamond with their hands.
- Shown in "Message Received", "Back to the Moon", "That Will Be All", and "Legs From Here to Homeworld", Homeworld Gems distinguish themselves from others of their type via codes and serial numbers based on Facet and Cut. For instance, Peridot is identified as "Peridot Facet-2F5L Cut-5XG."
- Judging by Peridot's Twitter account having the name "Peridot5XG", it can be assumed that the cut portion of a Gem's identification serves as their principal means of identification. The facet code is most likely the era in which the Gem was created (2 for Peridot), followed by the official name of the facet. Since "Eyeball"'s identification code also contains an F in its facet portion, it is possible that the F is merely a placeholder for Facet and that the final numbers following indicate the Gem's respective facet.
- In "Log Date 7 15 2", it is shown that Homeworld's galaxy can be seen with the naked eye from Earth.
- Although the color may be a factor, it is currently unknown how gems are specifically distributed between the courts of each Diamond.
- As Peridot was made on Homeworld, this proves that like Earth, Homeworld has Peridotite minerals. It is most likely that Homeworld has other similar minerals to Earth.
- Due to Lapis' reaction to them in "Same Old World", and the fact that it does not rain on Homeworld, it can be presumed there are no trees on Homeworld.
- In "Too Short to Ride", it is revealed that Homeworld is currently low on resources and, due to this, they are unable to create Gems with standard Gem abilities. However, the fact that Peridot is now known to possess ferrokinetic abilities suggests that resources are not as scarce as Peridot claims since the only standard Gem ability she is shown to lack is shapeshifting.
- In addition to disliking fusion, Homeworld also seems to have an unfavorable view towards shapeshifting. Peridot calls it "an insult to your intended form." Jasper calls it "reshaping yourself outside your purpose."
- However, similar to fusion, shapeshifting most likely does have a useful purpose for Homeworld for Era 1 Gems to be given this power in the first place.
- Although the Gems speak English, they have their own writing system.
- Bismuth's dialogue in "Bismuth" indicates that Homeworld itself was untouched by "the Rebellion".
- In "That Will Be All", it is revealed that the remaining Rose Quartzes are being held in bubbles, due to Blue Diamond not wanting to shatter them in keeping Pink Diamond's legacy.
- In "Lars' Head", it is revealed that all Gems with no contact with Earth are under the impression that it was destroyed when the Diamonds attacked it. This suggests that false propaganda meant to uphold the Diamonds' image of superiority is spread throughout Homeworld.
- As shown in "Off Colors", there appears to be water on Homeworld, seen dripping from the ceiling of the cave where Steven and Lars met the Rutile Twins.
- Homeworld's environment is similar to the sci-fi futuristic world of Studio Ghibli's animated music video "On Your Mark" that was released in 1995.
- Reflective surfaces appear to be extremely rare on Homeworld: when in "Catch and Release" Peridot glimpsed her reflection in a mirror, she was visibly surprised and regarded it with curiosity.
- Her "smiling" at her reflection is a common action for primates unfamiliar with mirrors: this gesture shows they possess a sense of self and permits them to see a part of their body – their teeth – that is normally hidden from sight.
- The Mirror Lapis was trapped in is an artifact from Era 1 which may have become obsolete by the time Peridot emerged (and, unlike Earth mirrors, it was not used as a looking-glass), or she may simply never had the chance to come across any such items.
- According to Joe Johnston, Pearls are specially made for their owners and they are "programmed" to follow the orders of their masters.
- Pearls are able to quibble their way around orders. For example, when Pearl was specifically ordered never to speak of the circumstances surrounding Pink Diamond's faked shattering, this did not prevent her from guiding Steven to discover the truth. Furthermore, because she was specifically told that the purpose of her final order was to make sure that no one would ever find out what really happened, she could easily disregard the order as obsolete as soon as someone found out the secret.
