In fanfiction, Black Diamond's story can be used to explore themes like redemption and forgiveness. If she was once a tyrant, her journey towards becoming a better being can be a powerful narrative.

Peridot is a character that could be paired with Yellow Diamond in fanfiction. Since Peridot was once under Yellow Diamond's rule, there can be stories about her loyalty, her possible defection, or how Yellow Diamond views her.
