Minor Characters/Gems

"Minor Gem Characters" are Gems who have been shown and 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 voiced by Charlyne Yi.

Ruby (fusion)
The fusion of all three Rubies in "The Answer".

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. She is 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 and a pointed nose and pixie hair-cut.

She has sky blue skin and long, messy periwinkle hair. In the fashion of her owner, Blue Diamond, her eyes are secluded by her bangs and her gem, a powder-blue pearl, is on her chest. Her outfit consists of a periwinkle bodysuit with an open diamond-shaped keyhole neckline, a knee-length, frost blue, sheer tutu, and no footwear. Her gem 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 a puffy canary yellow sheer silk 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 Gem, a yellow pearl, is on her chest, 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.

Trivia

 * It appears that Gems of the same gemstone also share the same voice, albeit with some differences in tone. Their appearances are also near identical, with the exception of Gem placement and minor details.
 * It can be inferred that Rubies are not assigned to a diamond when they are created, hence there being no diamond on their outfits.
 * According to Ian Jones-Quartey, if the Pearls fused, they would form a bigger Pearl with combined colors.
