Amethyst x Ruby.

Anything that wasn't completely brash and reckless about Sugilite (for instance the smart remarks) is completely absent. Bismuth isn't afraid to show her "true colors" (OH GOD A PUN) and just doesn't care much for anyone other than Sapphire. She's most likely to trigger someone by blurting something offensive. When given a goal, she'll stop at nothing to complete it.
