Ruby, nicknamed Doc by Steven, is a Homeworld Gem who made her debut in "Hit the Diamond". She is the leader of the Ruby troops sent by Yellow Diamond to retrieve Jasper. She was last seen floating in space after Steven opened the airlock on the Moon Base, although it is unknown if Navy saved her.

Appearance

Doc's complexion is the same as the Crystal Gem Ruby's in color, but she wears a yellow transparent visor similar to Peridot's and a pair of red shorts, held on by a pair of black suspenders that have two halves of a yellow diamond on the edges. Her gemstone is located on her chest.

Personality

Doc is a natural leader, assertive and professional in her actions. While the others are often distracted, she stays on task. She is the most competent member of the group along with "Eyeball", who is more experienced in Gem history, due to being older than her. She uses strict and commanding language when interacting with the other Rubies, but is very respectful towards Amethyst (who was shape-shifting to appear like Jasper).

Like the other Rubies, Doc is easily fooled by disguises or lies. She also made the error of not including herself in counting the group when she noticed too many Rubies standing about.

History

"Hit the Diamond"

Doc and her squad of Rubies prepare to search for Jasper after arriving on Earth. They notice a nearby barn and decide to search it. Steven is able to fool them, however, convincing them that they need to win a game of baseball before they can check the barn. The Ruby squad and the Crystal Gem Ruby constitute the Ruby team. They face off against the human team: Steven, Pearl, Amethyst, Lapis Lazuli, and Sapphire. Doc plays as the pitcher for the Rubies. They are able to take the lead in the top of the ninth, but ultimately lose when Sapphire hits a two-run home run in the second half of the inning. When Sapphire reaches the home plate, she accidentally fuses with Ruby, revealing themselves to be Gems. The Homeworld Rubies realize they have been deceived and fuse together. Peridot runs out of the barn to help the other Crystal Gems. Upon learning that she was assigned to the Earth mission, the Ruby fusion demands that Peridot tell her where Jasper is. Steven tells her that Jasper is on Neptune, convincing the Rubies and prompting them to defuse. They board their Roaming Eye and head to Neptune.

"Earthlings"

Doc and her Ruby squad return to Earth. After arriving, the Rubies are imprisoned in water bubbles by Lapis.

"Back to the Moon"

The Rubies are released from their water bubbles and questioned by Steven. He asks them why they have returned, and Doc reveals to the Crystal Gems that they have realized they have been deceived again, being unable to find Jasper after searching for her on Neptune and all the other planets in the solar system. She angrily demands that they tell her where Jasper is. The Rubies are tricked again, however, when they take Amethyst for Jasper after she had shape-shifted into the Homeworld Gem. Doc informs her that Yellow Diamond is awaiting her return and that they can take her back to Homeworld. Amethyst convinces the Rubies to allow her to stay on Earth with the pretext of keeping the Crystal Gems prisoner. Using the Roaming Eye, the Rubies and the Crystal Gems travel to the Moon Base after Doc tells Amethyst that she will need to file a report to Yellow Diamond. At the base, they discover the main panel destroyed and the Diamond Communicator missing. After Amethyst gives Eyeball the task of filing the report for her back on Homeworld, the Rubies board the Roaming Eye and prepare to leave. Doc exits the ship to offer Amethyst a ride back to Earth, and sees her in her normal form. With her disguise revealed, Doc orders the other Rubies to assemble and they fuse to fight the Crystal Gems. After Steven opens the airlock, Sardonyx forces the Ruby fusion to un-fuse and the Rubies are sucked out into the vacuum of space.

"Adventures in Light Distortion"

When the Gems and Steven leave Earth in the Roaming Eye on their way to rescue Greg from Pink Diamond's Zoo, they accidentally hit Doc and she sticks to the windshield briefly before rolling off.

Abilities

  • Pyrokinetic Touch: Like the Crystal Gem Ruby, Doc is shown to be able to set things on fire by touching them. This is shown in "Hit the Diamond" when she sets the baseball on fire before throwing it.
  • Photokinesis: In "Back to the Moon", she is shown projecting a red light from her gem as the Gems exit the Roaming Eye. She shares this ability with Garnet, Pearl, Peridot, Eyeball, and the Rutile Twins.
  • Piloting: As shown in "Back to the Moon", she is an expert pilot who is able to fly the Roaming Eye. She shares these skills with Pearl, Peridot, and Navy.

Fusions

  • When fused with multiple Rubies, specifically "Eyeball", "Army", "Navy", and "Leggy", they form a larger Ruby.

Appearances

Relationships

Other Rubies

Doc is the leader of the group, commanding them around and initiating their fusion by calling out "Rubies assemble!" She is a strict leader, often reminding the others to focus on the mission at hand. In her strictness, she is a bit rude, as she pushed Leggy out of their spaceship in the beginning of "Hit the Diamond" when the unsure latter was taking too long to get out. However, she also grabbed Leggy's hand at the end of said episode to make her come with them, demonstrating some care to not leave her behind. During their fusion, she stands in the middle, being the connection point to all the other Rubies.

Crystal Gems

Doc, like the rest of the Homeworld Gems, expresses dislike for the Crystal Gems for being their enemies, but also for being tricked and lied to. During the baseball game in "Hit the Diamond", she befriended the Crystal Gem Ruby thinking she was a Homeworld Gem, but was later shown to dislike her when she and Sapphire fused and exposed their identities as Gems.

Amethyst

In "Back to the Moon", Amethyst shape-shifts into Jasper to fool the Rubies again. Amethyst is able to impress and amuse the Rubies, making them comfortable in her presence. They sympathize with her story of keeping the Crystal Gems prisoner, crying and clapping because of her apparent devotion. They are seen playing along with her when she pokes fun at Pearl for being talkative, kicks some dirt to demonstrate her animosity towards the Earth, or gives the Crystal Gems the silly nickname Crystal Germs.

Doc uses respectful language when talking to her, and offers her the captain's seat in the Roaming Eye when they decide to head to the Moon Base. Doc is happily surprised and blushes when Amethyst pulls her to sit on her lap and even offers to do it again when asking Amethyst if she needs a ride back to Earth at the end of "Back to the Moon".

When Amethyst reveals her true form, Doc becomes angry at having been tricked again, and orders her team to attack the Crystal Gems.

Yellow Diamond

She mentions Yellow Diamond frequently, reminding the other Rubies that they cannot mess their mission up, as they had received direct orders from her. Surprisingly, Doc rather informally refers to her as just "Yellow" in "Back to the Moon", when she tells the others that "Yellow will definitely wanna know about ["Jasper" capturing the Crystal Gems]".

Gemology

Ruby In Real Life

Natural ruby.

Gemstone Information


  • Rubies are composed of a material known as corundum, the second hardest crystal structure after diamond (9,10 on the Mohs Scale of Hardness).
    • Since Ruby is a member of the corundum group, it is closely related to sapphire and thus shares some properties with it, such as hardness, composition, and double refraction.
    • In its pure form, corundum is colorless.
    • Rubies are the most expensive colored stone, going by carat.[1]
  • The word "ruby" comes from the Latin 'ruber' meaning red and, like many other gemstones, the ruby's symbolic meaning is heavily dependent on its coloring.
  • Natural Ruby is one of four "precious" gemstones (including diamond, emerald, and sapphire), known for its rarity, monetary value, and hardness (second only to diamond).
    • Natural Ruby can be distinguished from synthetic ruby by its inclusions; natural ruby typically exhibits inclusions, whereas synthetic ruby tends to be eye clean.
  • The color of ruby is its most important quality factor. The most sought after color is a strong pure red to red with a hint of blue, called pigeon's blood.
    • The vivid red color of ruby means that it is associated with desire, and it is thought by some to be a stone of love with an aphrodisiac effect.
    • When the color of ruby is too light, it is classified as pink sapphire, but the line between pinkish-red ruby and pink sapphire varies by region.
  • The ruby is closely associated with aspects such as vitality, life, passion and fire, all of which can be symbolically linked to the color red.
    • This shows in Ruby's emotional temperaments and overall emotional/angry attitude as well as her strength.
    • It is said that rubies can over-stimulate people who are sensitive or irritable.
  • Ruby is the traditional birthstone of those born in July and is also the zodiacal stone for Cancer and Aries.
    • Ruby is also used to celebrate the fifteenth and fortieth wedding anniversaries.
    • The day assigned to Ruby is Tuesday (hence the Rolling Stones song, "Ruby Tuesday").
    • The planet Mars is famously known as "the red planet", due to the high concentration of iron oxide (basically rust) on its surface and rubies, along with all of the aspects mentioned above, have been linked with Mars in one form or another.
    • Ruby is the national gemstone of Burma and Thailand.
