Obsidian is a Homeworld Gem and a subordinate of White Diamond. She was created by Lenhi.


Obsidian was made eons ago for White Diamond in order to assist in expanding the Gem empire by surveying newly discovered celestial bodies in order to evaluate whether or not they are viable as potential colonies or material mines. She is one of few remaining Obsidians made from the original template, and, as a result, has a higher status and more abilities than other, newer varieties of Obsidian.




Obsidian is a Gem with an average slender build and dark grey-toned skin. She has white, slightly-waved hair that is swirled to the side with her bangs covering the right-side of her face. She only has one eye which is a dull purple color.



Obsidian possesses standard Gem abilities and traits.


Skill set

  • Intelligence: As an Obsidian, she is very knowledgeable when surveying celestial bodies, knowing how to efficiently utilize resources, as well as being able to identify what conditions are best suited for certain things such as Gem incubation and what materials are worth putting in time and effort to mine.

  • She was the first Gem created by Lenhi and was originally their Gemsona.
