Minor Characters/Gems

"Minor Gem Characters" are Gems who have debuted and been identified, but, as of yet, hold no significant nor recurring roles.

Ruby (right shoulder gem)
"Ruby" is a Gem who appears in "The Answer".

She appears to be identical to the Crystal Gem Ruby and the other Ruby in their Gem trio in appearance, clothing, and voice. She and the other Ruby seem to be obsessed with fighting. Her gemstone is also identical and is placed on her right shoulder. She is voiced by Charlyne Yi, who also voices the Crystal Gem Ruby.

Ruby (right back-hand gem)
"Ruby" is a Gem who appears in "The Answer".

She appears to be identical to the Crystal Gem Ruby and the other Ruby in their Gem trio in appearance, clothing, and voice. She and the other Ruby seem to be obsessed with fighting. Her gemstone is also identical and is placed on the back of her right hand. She is also voiced by Charlyne Yi.

Ruby (triple fusion)
"Ruby" is the fusion of all three Rubies in "The Answer", one of which being Crystal Gem Ruby.

As their individual forms and gemstones are the same, their fusion remains identical except much larger in size. In this form they are much more powerful. However, the true extent of their strength in this form remains unclear because they fought against Rose Quartz, an extremely skilled and powerful warrior. The Crystal Gem Ruby describes the fusion as just "me, but bigger," implying the state of being is not that different for her unfused. She is also voiced by Charlyne Yi.

Blue Diamond's Pearl
Blue Diamond's Pearl is a Gem who appears in "The Answer".

Physically, she appears almost identical to the Crystal Gem Pearl and Yellow Diamond's Pearl, as she also possesses a thin, tall build, a pointed nose, and pixie haircut.

She has sky blue skin and chin-length, messy, periwinkle hair. In the fashion of her owner, Blue Diamond, her eyes are covered by her bangs. Her outfit consists of a periwinkle bodysuit with an open diamond-shaped keyhole neckline, a knee-length, frost blue, sheer skirt, and no footwear. Her gemstone, a powder-blue pearl, is on her chest and is a round polished cabochon.

She appears to be either relatively apathetic to what's happening around her, or doesn't speak unless spoken to.

Yellow Diamond's Pearl
Yellow Diamond's Pearl, also known as Yellow Pearl in the credits, is a Gem who appears in "Message Received". She works as Yellow Diamond's receptionist, taking her call on the Diamond Communicator.

Her build and facial features are similar to that of Pearl of the Crystal Gems and Blue Diamond's Pearl. She sports a beige or pale peach maillot with a similar bustline to Blue Diamond's Pearl. She also wears puffy, canary yellow, sheer shoulder sleeves, and no skirt, as well as pale yellow long stockings and bright yellow flats. In the fashion of her owner, she has a puffy yellow pixie hair-cut that is pointy and in a similar bob design and pale yellow skin. Her gemstone, a yellow pearl, is on her chest and is a round polished cabochon, similar to Blue Diamond's Pearl.

She is shown to have a bad temper and finds satisfaction in other's misfortunes, as well as having a fearful attitude towards Yellow Diamond, to whom she refers to as "My Diamond", much like Peridot.

She is voiced by Deedee Magno-Hall, who also voices the Crystal Gem Pearl.

Gems From Upcoming Episodes
{{Spoiler|

Ruby (left eye gem)
"Ruby" is a Gem who appears in "Barn Mates" and "Hit the Diamond".

She is a part of the Ruby troops sent by Yellow Diamond to retrieve Jasper. She seems to be the most invested on the mission to track Jasper, and is the most stoic, barely saying anything. She seems anxious about something. She is intimidating and scary at most, but she reveals to be quite polite when she thanks the Crystal Gems for their cooperation. Her gem is in her left eye, and her outfit consists of the regular Homeworld uniform. She has the lightest complexion than the rest of the Ruby troops.

Ruby (chest gem)
"Ruby" is a Gem who appears in "Hit the Diamond".

She is the leader of the Ruby troops sent by Yellow Diamond. She is assertive and a natural leader, professional in her actions. Her complexion is the same as the Crystal Gem Ruby's in colour, but she wears a yellow transparent visor 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. She does not wear a shirt, so it's easy to assume she's somewhat androgynous (or even masculine). Her gem is located in her chest. She is also voiced by Charlyne Yi.

Ruby (left shoulder gem)
"Ruby" is a Gem who appears in "Hit the Diamond".

She is a part of the Ruby troops sent by Yellow Diamond and is the most violent of all. She is always fighting with something or someone and gets angered easily. Her skin hue is more orange in color than the other Rubies and her gem is on her left shoulder. Her outfit is the usual Homeworld worker design, with red shorts, and a top with a deep triangular collar, with black trims that meet to form a yellow diamond sign. She also has a unibrow.

Ruby (solar plexus gem)
"Ruby" is a Gem who appears in "Hit the Diamond".

She is part of the Ruby troops sent by Yellow Diamond and appears to be way more gleeful than the other Rubies of the troop. She is amused by the Earth, expresses constant satisfaction, is oblivious to everything, and is dramatic in her mannerisms. Her gem is in her stomach, on her solar plexus. Her outfit features a red shawl-like top on her torso that opens around her solar plexus, and has a yellow diamond on the collar. She has more of a cherry complexion.

Ruby (left knee gem)
"Ruby" is a Gem who appears in "Hit the Diamond".

She is a recently created Ruby who's new to her job as part of the Ruby troop, referred to as "Newbie" by her fellow Rubies. She seems to be the most disorientated and confused, never knowing quite what to do. She's also the most fearful, frequently hiding behind other things. Her outfit is the regular Homeworld uniform, with her gem on her knee. Her complexion is the darkest of the Ruby troop, being more of a burgundy color.

Ruby (quintuple fusion)
"Ruby" is the fusion of all five Rubies in "Hit the Diamond".

As their individual forms and gemstones are the same (minus the left eye gemstone fitting over the left pupil), their fusion remains identical with the exception of a larger size, and a slight outfit variation (including one Ruby's yellow visor). She is also voiced by Charlyne Yi. }}

Trivia

 * It appears so far that Gems of the same gemstone also share the same voice, albeit with some differences in tone save possibly for Lazuli Gems, Quartzes and of course, Diamonds. Their appearances are also near identical, with the exception of gemstone placement and minor details.
 * According to Ian Jones-Quartey, if the Pearls fused, they would form a bigger Pearl with combined colors.
