Blue Diamond

Blue is a very mellow Diamond who treats high-ranking members of her court with respect, given her assigned role to act as an enforcer and arbiter of Gem society. According to?Holly Blue Agate, Blue Diamond has a reputation for mercy and forgiveness. Blue Diamond's temperament appears to have changed significantly in the 5,000 years following the supposed shattering of Pink Diamond. She fell into a prolonged state of grief and depression. She is unable to let go of the past, becoming fixated on preserving Pink Diamond's legacy. Her efforts to maintain the late diamond's zoo, save Earth specimens from the Cluster's emergence, and her refusal to shatter the Rose Quartzes that once served under Pink Diamond shows this behavior. She continues to regard the Earth as Pink Diamond's colony. Blue is extremely diplomatic. Blue wants everyone around her to feel the pain she feels from losing Pink, but despite seeking to do them harm it only made the pain she felt worsen and her longing to see Pink grow. but, when she is not grieving, Blue is a very caring individual. ?Additionally, Blue is shown to have a humorous side to her. Despite her more merciful, compassionate, and forgiving nature, she is shown to be extremely unforgiving and derogatory towards fusions of different gems, something that she shares in common with Yellow Diamond. Due to their roles as the Gem matriarchs, Blue and Yellow Diamond treat each other with respect, considering themselves equals. However, Pink Diamond's shattering is a source of friction between them, as Yellow and Blue Diamond have been arguing for thousands of years over their different ways of coping with the loss of Pink Diamond. Despite their differing beliefs, they still care about each other, and often comforted one another. Their attitude toward legal matters suits their roles as overruling authority figures.
