|Behind the Scenes|
Rubies are a subspecies of Gem with fire-related powers.
Rubies have bright scarlet skin, burgundy irises, dark burgundy square-shaped hair, thick builds, and outfits in various shades of red.
Rubies appear to be used as personal escorts and bodyguards for high-ranking Gems. They are considered somewhat unimportant to other Gem types and viewed as nothing more than expendable grunts, though they compensate this trait by merging with each other into Fusions resembling larger versions of themselves.
