Personality
Grey Obsidian is morose and ruthless. She is skilled with Gem technology and works for the Homeworld Gems as a military strategist and takes her work seriously, because this job can't be treated differently. She thinks mainly of her own needs. Grey Obsidian prioritizes logic, reason, and objectivity above emotions. She is great at problem-solving as she uses her own observations to make a conclusion. Grey Obsidian feels that a practical and systematic approach is the correct way to do things. When a cause is important to her, she is extremely emotionally charged.

Grey Obsidian is also incredibly stubborn, dedicated and possessive, occasionally to the point of obsession. When her strategy doesn't work, she starts panicking and trying to fix everything. She believes that running away is not the option - fight or die, that's her motto. However, Grey Obsidian is not so honest about her viewpoints and will not bluntly state what is on her mind. She is socially oblivious, but she is loyal towards people she respects, especially her superiors.

Grey Obsidian shows an aversion to fusion, due to the Homeworld belief that fusion should only be used for combat, but this aversion is mixed with inclination, as for her first fusion(White Rhinestone) they both felt stronger and bigger. Her reaction to her first fusion is similar to Jasper's, after she fused with Lapis Lazuli for the first time.
