Blue Diamond's debut portrays him as a very good-natured and mellow Diamond who treats high-ranking members of his court with respect. According to Holly Blue Agate, Blue Diamond has a reputation for mercy, sympathy, and forgiveness. "Saving" Greg from the threat of the Cluster after taking a liking to him, unaware that the Cluster is formerly inactive, demonstrates this. However, as with Yellow Diamond, his true nature may be at odds with his reputation, as he sentences Ruby to shattering for accidentally fusing with Sapphire while trying to do her job and saving her by accident. However, it is unknown if his personality has changed over the millennia after Pink Diamonds death. Blue Diamond's temperament appears to have changed significantly in the 5,000 years following the death of Pink Diamond. he was in a state of great depression, still mourning over the shattering of his fellow diamond. he is unable to let go of the past, becoming fixated on preserving Pink Diamond's legacy. His efforts to maintain the late diamond's zoo, save Earth specimens from the Cluster's emergence, and his refusal to shatter the rose quartzes that once served under Pink Diamond shows this behavior. he continues to regard the Earth as Pink Diamond's colony, and, due to being unaware that the Cluster is bubbled, is visibly saddened by the fact that the planet will eventually be destroyed. Additionally, Blue Diamond seems to misunderstand humans, given by how he was surprised that Greg was able to comprehend and sympathize with her pain of losing a loved one. As shown in the episode "The Trial", Blue Diamond is extremely opportunistic, diplomatic, and dexterous. Against Yellow Diamond's wishes, he allowed Steven to continue making his case during his trial, though he did lose his temper when his recounting of events differed. he nonetheless seemed to want to hear Blue Zircon's theory on how and why Pink Diamond was shattered. When Yellow Diamond snaps and poofs both Zircons present at the trial, Blue Diamond confronts him and scolds him for not having enough restraint to hear the case out. This shows that Blue Diamond may be as merciful, forgiving, and sympathetic as his gems claim – at the very least, he certainly has a greater respect for due process and an interest in the truth. However, despite hid more merciful and forgiving nature, he is shown to be extremely unforgiving and derogatory towards fusions of different gems, something that he shares in common with Yellow Diamond. This is first seen when Blue Diamond sentenced Ruby to be shattered just for fusing with Sapphire out of a desire to save her life, demonstrating his ruthlessness towards these situations. Even after 5,000 years, his attitude towards these situations has not changed. When conversing with Steven, he mocked Garnet's fusion and stated that he didn't belong anywhere. Then, when Steven and Connie fused, Blue Diamond lashed out at Steven, viewing such a fusion as extremely inappropriate, and demanded they unfuse immediately. he also had no qualms about locking Steven up as punishment for his actions. Despite this, his tyrannical ways appear to be merely him enforcing White Diamond's rules on Homeworld, and that he and Yellow are in fact miserable under White's rule. he is also shown to be empathetic enough to understand that the Homeworld Gems are suffering because of the Diamonds' ways. After making amends with White, Blue appears to be much kinder and more benign, accepting the Crystal Gems and Off Colors, in addition to being the one to figure out how the Diamonds can cure the Corrupted Gems.
