Jasper
- Gem: Jasper
- Weapon: Crash Helmet
- Known fusion: Malachite (with Lapis Lazuli)
Jasper (voiced by Kimberly Brooks) – A tall, muscular Homeworld Gem who is Peridot's escort on their mission to Earth. She was a veteran of the original war on Earth, on the Homeworld's side. She has an especially angry and violent personality and is contemptuous of those she considers weak (although she considered Rose Quartz a worthy adversary).
Her gem stone is an orange jasper embedded on her nose, and her weapon is a helmet shaped like a Japanese punk pompadour; she is a powerful physical combatant who can charge at her opponents with a "spin attack" in a manner similar to Amethyst.
In her first appearance, she also had access to a cattle prod-like "Gem destabilizer" that immediately disrupts a Gem's physical form on contact (a similar device used by Peridot proved ineffective on Steven's half-human physiology).
At the end of 'Jail Break', she fuses with Lapis Lazuli to form the monstrous Malachite in an attempt to exact revenge, but Lapis uses her hydrokinetic abilities while fused to imprison them both at the bottom of the ocean. Jasper made a short appearance in one of Steven's dreams in "Chille Tid".
