"Rose's Sword" is a weapon that formerly belonged to Rose Quartz. It was discovered by Steven and Connie in "Lion 2: The Movie", and is currently stored inside its scabbard in the pocket dimension inside Lion's mane.
The sword has a slightly dark pink pommel resembling a rosebud with a rose quartz embedded in it. The guard and knuckle bow of the sword is pink with the guard having an image of a four-petaled white flower in the middle and the grip being dark pink; the grip, guard, and knuckle bow are inscribed with a twirling thorn design. The sword's cupped hilt and broad blade with its tanto tip are reminiscent of a 17th-century military cutlass. This bright pink blade emits a white aura when pulled from Lion's head. At the base of the blade, the rain guard is shaped like a pink rose with the two outer petals being dark pink.
Rose's Sword first appeared in the episode "Lion 2: The Movie". Steven asked Lion for help when he and Connie were attacked by the Robot Shooty Thing so Lion responded with a glowing mane and eyes whilst the hilt of the sword materialized on his head. Steven pulled out the glowing sword and he and Connie volleyed the elemental blasts back using Connie's tennis skills (previously mentioned in the episode) at the Robot Shooty Thing in order to destroy it.
In "Lion 3: Straight to Video", the sword is seen vertically standing in a pile of stones inside the pocket dimension in Lion's mane. The introduction of the pocket dimension and the revelation of the sword's location inside it indicates how Steven was able to pull the sword from Lion's head in "Lion 2: The Movie".
The sword appears once again in "Rose's Scabbard" after Lion finds Rose's Scabbard on the Gem Battlefield. Pearl states that Steven should have the Scabbard, and that Steven now also owns the sword that it once sheathed. After an unsuccessful trip to Rose's secret armory in an attempt to find the sword, Pearl shows Steven an image of the sword using a hologram, after which he exclaimed that he knew where it was. Back at the temple, Steven pulls the sword from Lion's pocket dimension, much to Pearl's surprise. Later at the Battlefield, the sword was returned into Lion's pocket dimension.
The sword appears in Pearl's hologram flashback of the war fought on the Gem Battlefield. Rose is shown wielding her shield and the sword against an unknown Gem of the opposing faction during the war.
