Pyrite

Gem: Pyrite
Nickname: Fool's Gold
Alignment: Homeworld / Yellow Diamond
Pronouns: She/Her
Height: About as tall as Steven and Peridot (minus limb enhancers)
Gem Location: Eye
Weapon: Pyrite’s weapon is a stylized chakram.  It is explosive, and can be struck against a solid object (ie the ground, rocks, etc) and ignited (like a match) before quickly thrown at a foe.  
Special abilities: She is extremely fast and agile, and she has often been known to talk her way out of trouble.
Fun Facts: Pyrite was a failed gem experiment which resulted in a damaged eye, a too-small physical form and a flawed gem.  She was initially going to be shattered but proved to be an asset to Yellow Diamond due to her speed and fierce allegiance to the Diamond Authority and Homeworld.  Pyrite is childish, rarely takes anything seriously and is constantly testing other gems’ patience, which tends to get her into trouble.  Despite her short stature, Pyrite is quite the foe in battle and outwits opponents with her high speed and trickery.
