The Gem Rejuvenator is a weapon used by Spinel in the Steven Universe: The Movie. The weapon possesses the ability to strip any Gem of their memories and reset them to their original self.


According to Bismuth, this weapon was once used on Homeworld to reset gems that defected. The only one known to have existed in the current day was Spinel's weapon of choice.


The Gem Rejuvenator, in its inactive state, is a magenta grip with a pink switch.

In its active state, the weapon resembles a magenta scythe with the blade made of pink energy.


The Gem Rejuvenator works similarly to the Gem Destabilizer. Any Gem struck with this weapon will immediately be poofed. However, upon reforming, the Gem will not remember anything other than its original designed purpose. The affected Gems will also revert to their original outfits.

It is possible to regain the memories of any Gems affected by recreating an event or triggering a feeling that has had a great influence over that particular Gem.

The weapon had a different effect on Steven Universe. Being a human/Gem hybrid, his Gem took the brunt of the attack. As a result, his powers were severely weakened. However, he still had some access to his powers, albeit weak, shown when he was incapable of summoning his Shield for longer than a few seconds.


  • It is unknown if Homeworld still uses these weapons, nor is it known how Spinel got her hands on one.
  • It is unknown if Homeworld used these weapons during the Gem War.
