Gagat originally came to Earth with many other gems including Bismuths, Rubies, Quartz' and other Gagats. Once the war began, however, she was almost completely forgotten. This led her to move away from the colonies and aimlessly wander the globe, which led her to the ancient Greek city-states, where she masqueraded as an actor for their famous theatre productions. Eventually Cuprite was sent to capture her and return her to Homeworld. However after her return it was realised that she no longer served a practical purpose for Homeworld, and as such she was exiled to Orlov Diamond.
Gagat possesses standard gem abilities such as shape-shifting, weapon summoning and bubbling gemstones.
