"Message Received"

In "Message Received", Yellow Diamond states that Peridot has a manager.

"Same Old World"

There are a few unknown Gems featured in Lapis' flashback.

"Monster Reunion"

There are a few unknown Gems featured in Nephrite's flashback.


These are the "other Crystal Gems" who were mentioned by Bismuth, except for Nephrite, who is most likely a Homeworld Gem. They appear to be her close friends. Their statuses and physical appearances are unknown.

The former Crystal Gems "Biggs" and "Snowflake" are mentioned, later revealed to be referring to Biggs Jasper and Snowflake Obsidian. Other former Crystal Gems are mentioned.

  • "Crazy Lace" - A former Crystal Gem mentioned by Bismuth. She is presumably a Crazy Lace Agate.
  • Other Amethysts - Former Crystal Gems mentioned by Bismuth.
  • Nephrite - A Homeworld ship pilot, mentioned by Bismuth to Pearl.


Many Corrupted Gems are seen trapped in cages in the Beta Kindergarten. Their bodies are hidden by shadows and only their glowing yellow eyes can be seen.

Additionally, Peridot mentions a Carnelian whose hole is misshaped in the Beta Kindergarten, later assumed to be Carnelian, a member of "the Famethyst" in "That Will Be All". Amethyst refers to one Gem with a thin exit hole as "skinny", later assumed to be a "Skinny" Jasper, a member of "the Famethyst" who debuted in the same episode as Carnelian.


Another Corrupted Gem can be seen in a cage. Only her two eyes and large six-clawed hand can be seen.

"Adventures in Light Distortion"

File:Unknown small gem.png


When Steven is adjusting the Roaming Eye's form calibration system for the Crystal Gems, a small type of Gem, possibly a Pebble, Aquamarine or gems of the Earth and Heaven Beetle type, can briefly be seen on the panel, which subsequently alters the Crystal Gems' forms to be small.

Adventures In Light Distortion 163.png

Also, a large type of Gem, presumably a Quartz, Topaz, Bismuth, Obsidian, or Tourmaline can be seen.

"That Will Be All"

That Will Be All 060.png

A countless number of Rose Quartz gems appear bubbled in a room of Pink Diamond's Zoo.

"The Trial"

The defending Zircon states that Pink Diamond's entourage did not contain any Rose Quartzes and was instead composed of several Agates and Sapphires.

"Off Colors"

Various pieces of old statues can be seen at the beginning of the episode. One appears to be a fusion of two unknown Gems, while the head of a large statue has a gemstone with the same cut as a Rose Quartz's on its forehead.

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

The Rutile Twins mention in that the moment they emerged, the other Rutiles who saw them ran away in fear because of how they looked.

Morganite, an unknown Gem, is mentioned by Rhodonite. She was in charge of the two halves of Rhodonite before she replaced them after she found out that they had fused.


Steven Universe Gemcation 149.png

During Garnet's brief flashback of the Rebellion, two unknown Gem silhouettes appear fighting Pink Diamond alongside Garnet, Pearl and Bismuth.

  • On the left of the image there is a Gem with short hair around the same height of Pearl. She appears to have a thin build. Her hair is similar to the Rutile Twins' or the prosecuting Zircon's.
  • On the right of the image there is a short Gem. She resembles one of the unknown Gems in "The Answer".

"Lars of the Stars"

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.

Nephrite-XJ Cut-763

"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"

During the flashback, many Quartzes belonging to Pink Diamond appeared, emerging from their incubation in the ground alongside Rose Quartz. The silhouettes of other Quartzes, whose purple coloring suggesting they are Amethysts, are also shown working in the kindergarten. 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.


"Now We're Only Falling Apart"

Three unknown quartzes, presumably Amethysts appear in a flashback alongside Pearl, Rose Quartz, and two Topazes. They have large hair covering their eyes and a Blue Diamond insignia on their uniforms.

"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.

  • "Tiger's Eye" - A corrupted Crystal Gem mentioned by Bismuth, formerly bubbled in the Burning Room, and presumably uncorrupted as of "Change Your Mind ".
  • "Larimar" - A corrupted Crystal Gem mentioned by Bismuth (nicknamed "Little Larimar"), formerly bubbled in the Burning Room, and presumably uncorrupted as of "Change Your Mind". Her nickname implies that she is of short stature.
  • "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 green Gems, presumably Peridots, 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 Sentient Statue 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.

The green Gems of this type (that are seen in "Together Alone") have their rectangular gemstones on their forehead.
These green Gems are taller than usual, with long turtlenecks and long heads. They have no shoulder pads, and they have long wide sleeves. Their skirts have an open overskirt that drapes over, forming a triangle. They have rectangular, faceted gemstones.

They are colored in:

  • green (forehead gems), and
  • dark green (left hand gems).
Many Gems of this type are seen at the Ball, saluting the Diamonds.

The dark green Gems of this type (that are seen in "Together Alone") have their rectangular gemstones on the back of their left hands.
  • There is a green statue-like Gem (or Gem-powered object) with a disco ball contained within it, as wells large green hands. Whether or not if this disco ball is this Gem's gemstone or not is currently unknown. 

"Change Your Mind"

In Steven's dream flashback, Blue Diamond mentions a Kyanite colony, though whether she was referring to a planet called Kyanite or a planet that produces Kyanite Gems is unclear. The silhouettes of unknown Gems can be seen surrounding and staring at Steven during his dream. Inside Yellow Diamond's bubble room, there are a number of unknown bubbled cluster gems. There are also yellow Sentient Bridges (presumably Gems or Gem-powered objects) seen leading to Yellow Diamond's bubble room, and on the bridge Yellow and Blue Diamond land on after the former shoves the latter through the bubble room wall.

Six unknown types of Quartz Gems can be seen in Rose's Fountain after having been healed from corruption. They all have different colors, skin patterns, and horns on their heads which they retained from when they were corrupted.

Image Physical Information
A white Quartz with straight blonde hair. She has two spikes on her shoulders, two teal spikes and two slightly larger blue ones, and two light blue and pink spikes on her head. She wears a dark purple top with a lighter purple sheer strap which goes up to her neck.

A light and dark grey striped Quartz with light blue-green hair and single striped horn on her head. She wears a black sleeveless top. 
A light blue Quartz with peach markings on her skin and dark blue wavy hair. She has three light blue spikes with the same peach markings on two of them on her head and wears a strapless dark grey top. 
A greyish-lavendar Quartz with black and grey hair. She has two light purple spikes on her head and wears a strapless top which is similar to Rhodonite's. Her gemstone is located on her chest, although its exact cut is difficult to see.
A mint-green Quartz who wears a dark green, strapless top. She has two spikes on her head and pink splotches throughout her body. She strongly resembles the Snow Monster's uncorrupted form, and is likely the same type of gem.

A multicolored Quartz that is larger than the others, she has thick peach hair tied back with red and yellow ribbons, and a sleeveless gray v-neck with a dull green lace. She has either a gemstone or a horn where her nose should be and her visible eye is diagonally split; the top side is yellow with a red pupil, while the bottom is white with a mocha pupil.

A Gem with thick brown hair can be seen from behind talking to the healed Snow Monster, but no other details of her are shown.
