Rhodonite's components are an unknown Ruby and Pearl, while Fluorite's components are six unknown Gems.

"Lars of the Stars"

Nephrite-XJ Cut-763

A group of sixty-seven elite Citrines is mentioned by Emerald to have guarded her fastest ship, the Sun Incinerator, on the docking bay of the planet Klavius 7. Lars and the Off Colors are able to successfully sneak past all of the guards in order to steal the ship. Emerald also mentions that one of the crimes Lars and the Off Colors are accused of is impersonating imperial officers in a cosmic jubilee. While pursuing the Off Colors in her Destiny Destroyer, Emerald commands her crew, who remain offscreen, to fire on the Sun Incinerator's nova thrusters.

"Jungle Moon"

In Stevonnie's dream, the name shown on Dr. Maheswaran (who represents Yellow Diamond in the dream)'s phone is Nephrite-XJ Cut-763. She seems to have been reluctant to begin colonizing the planet due to the presence of organic life, causing Yellow Diamond to demand her to do her job, threatening to shatter her and her crew herself otherwise. According to the silhouette on the phone, she has spiky hair.

Yellow Diamond also attempts to contact the leader of the fleet, however, Pink Diamond interrupts her, so the leader's name and appearance are never shown.

"Your Mother and Mine"

Unknown Crystal Gems also appeared in the flashback, standing alongside Rose and fighting unknown Homeworld Gems at the Ancient Sky Arena.

Near the end of the episode, Rhodonite said there will be Agates on one of Yellow Diamond's Asteroid Mines that they were heading towards.

"A Single Pale Rose"

While Steven is in Pearl's gemstone, he presumably discovered her memories of the abandoned Gem Battlefield the second Pearl sent him to. There when he fell, he saw gemstones of inactive Gems in the sand. Later in the scene when Steven comes back from Pearl's gemstone, there are many Gems that witnessed Pink Diamond's shattering. In a following scene, there is a flail-wielding white Gem that Garnet poofs, and a Gem with a sword that Pearl fights.


"The Question"

Ruby mentioned being surrounded by other Rubies before meeting Sapphire.

"Made of Honor"

After Bismuth is unbubbled in the Burning Room, she reveals the names of several bubbled (and presumably corrupted) former Crystal Gems that she recognized, including Larimar.

  • "Tiger's Eye" - A corrupted Crystal Gem mentioned by Bismuth, formerly bubbled in the Burning Room, and presumably uncorrupted as of "Change Your Mind ".
  • "Beryl" - A corrupted Crystal Gem mentioned by Bismuth, formerly bubbled in the Burning Room, and presumably uncorrupted as of "Change Your Mind".
  • "Serpentine" - A corrupted Crystal Gem mentioned by Bismuth, formerly bubbled in the Burning Room, and presumably uncorrupted as of "Change Your Mind".

"Legs From Here to Homeworld"

Upon the arrival of Pink Diamond's ship, many Gems are seen cheering for the Diamonds. Among the Gems seen in the close-up of the crowd are a group of tall green Gems (possibly Peridots or a related type of gem) a group of short pink Gems, a group of pale blue Gems, and a group of flying Aquamarines.


Yellow Diamond is mentioned to be checking up on Citrine production reports.

Blue Diamond mentions that Pink Diamond used to call a batch of Pyrite "Fool's Gold".

There are several polygonal yellow Sentient Walls (presumably Gems or Gem-powered objects) that seem to make up the wall in the hallway leading to Yellow Diamond's Extraction Chamber. They all have a rhombus-shaped yellow gemstone on their forehead.

There is also a making up part of the entryway to Blue Diamond's pool chamber. The statue is capable of blinking and has a round gemstone on their forehead, so they seem to be a Gem or a Gem-powered object like Lapis's mirror.

"Together Alone"

Various types of Garnets — Demantoids, Hessonites, and Pyropes — are mentioned by Blue Diamond when she taunts Garnet. In addition, some unknown gems can be seen attending the Era 3 Ball. In addition to various JadesAquamarines, Amethysts, Jaspers, Rubies, and Sapphires, these blue-green gems can be seen. Several exact duplicates of these two Gems appear, likely to fill crowd space.

  • There are two green statue-like Gems (or Gem-powered objects), each with a disco ball inside of their cage-like bodies and two large outstretched hands. 

"Change Your Mind"

In Steven's dream flashback, Blue Diamond mentions a Kyanite colony. The silhouettes of unknown Gems can be seen surrounding and staring at Steven during his dream. Inside Yellow Diamond's bubble chamber, there are a number of unknown bubbled cluster gems. There are also yellow Sentient Bridges (presumably Gem-powered objects) seen leading to Yellow Diamond's bubble chamber and on the bridge Yellow and Blue Diamond land on during their fight.

Steven Universe: The Movie

During the broadcast of Steven's message, many unidentified Gems are gathered in a crowd at the Diamond Palace. On an unknown planet, several unidentified Gems can be seen viewing the message from Steven on a beach, including two gems resembling the Heaven and Earth Beetles, and a Peridot.  On another unknown planet dominated by a large city, a group of Gems are watching Steven's message from a balcony. This group includes two Zircons, a Holly Blue Agate, Gem that's presumably a Lapis Lazuli, two Topazes, a Jasper, a Ruby, a Pearl, and two Peridots.

  • The unknown Quartz warrior in "Sworn to the Sword" is voiced by Michaela Dietz, implying she may be an Amethyst.

    • "Crazy Lace" is a variety of agate.
    • "Tiger’s Eye" is a variety of quartz.
    • "Beryl" is a rock type that includes the gems aquamarine, emerald, and morganite.
    • "Serpentine" refers to different gems that come from the rock Serpentinite.
  • Pink Diamond calling the Pyrites "Fool's Gold" is a tie to the nickname given to that rock in real life.
