As shown in her debut, Blue Diamond is portrayed as a very mellow Diamond who treats high-ranking members of her court with respect. According to Holly Blue Agate, Blue Diamond has a reputation for mercy and forgiveness. This is demonstrated when she "saves" Greg from the threat of the Cluster after taking a liking to him, unaware that the Cluster is no longer active. However, as with Yellow Diamond, her true nature may be at odds with her reputation, as she sentences Ruby to shattering for accidentally fusing with Sapphire while trying to do her job.
Blue Diamond is currently in a state of great depression, having mourned the loss of Pink Diamond for thousands of years after her shattering. She has issues letting go and moving on, instead clinging to any reminders of Pink Diamond's presence. However, she can still be firm when the situation calls for it.
Additionally, Blue Diamond seems to not understand humans, given by how she was surprised that Greg (a human) was able to understand and sympathize with her pain of losing a loved one, and while she considered it a shame that Earth would be destroyed by the Cluster, she does not appear to intend to do anything to prevent it.
