Holly Blue Agate is a Homeworld Gem, and an original character that appears in Steven Universe.


Holly Blue Agate has an appearance similar to that of other Agates, as she is tall and bulky with short hair. Her skin is periwinkle and she has two large dull lavender eyes with black pupils, a sloped nose, and a large mouth with full lips. Her hair is in a short updo that has two outward points, and her hair is banded in colors of light cool magenta, white, and light lavender. Her gemstone is located on the back of her head and is cool blue.

She wears a black and dark blue sleeveless bodysuit with tall white high heeled boots, and over her shoulders is a royal blue shawl with a Blue Diamond insignia on it.


Matronly and methodical, Holly Blue Agate oversees Pink Diamond’s Zoo with little tolerance for a lapse in protocol. She serves as an attaché to Blue Diamond and takes her job very seriously. She manages the base and its employees when Blue Diamond is not around, showing skill in leadership and management. Her severity is matched only by her elitism, as she is rough and rude to the Quartz Gems that inhabit the facility, yet obsequious to Gems of higher social status than her own.


Holly Blue Agate possesses standard Gem abilities, bubbling, shapeshifting, fusion, regeneration, agelessness, and superhuman strength/durability. As a Quartz-type Gem, she is easily strong enough to deliver painful blows to other Quartz Gems. However, against multiple opponents such as the Crystal Gems, she can be easily dispatched.



  • Electric Whip Proficiency: With the desire to discipline others, Holly Blue can summon a blue whip with electrical currents running down it. The whip appears to have the same durability as Amethyst’s whip since Pearl’s spear easily cuts both.
