Rubies

Rubies are common solider Gems used by Homeworld, usually for body guarding. All Rubies shown so far, including the Crystal Gem's Ruby have been voiced by Charlyne Yi.

"The Answer"
Two Rubies appear in Garnet's flashback in "The Answer". They were sent (along with the Crystal Gem Ruby) to Earth to escort Sapphire to Blue Diamond. They were poofed by Pearl, and their fates are unknown.

They appear to be identical to the Crystal Gem Ruby and each other in appearance, clothing, and voice. Both Rubies seem to be obsessed with fighting.

They have identical gemstones in different locations.

"Together Alone"
Several Rubies are seen attending the "Era 3 Ball" in "Together Alone", accompanying various Sapphires.

The Rubies salute "Pink Diamond" (Steven), and many appear Sapphires appear later at the dance.
