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.

Trivia

 * It appears that Gems of the same gemstone also share the same voice, albeit with some differences in tone.
 * This does not include fusions of two different kinds of gems seeming as their voices are fused versions of the fusees voice.
 * It can be inferred that Rubies are not assigned to a diamond when they are created, hence there being no diamond on their outfits.
