The "Replicator Wand" is a magical tool that was formerly owned by Pearl. It was destroyed by Garnet in "Onion Trade".
About
The Replicator Wand is a magical tool that can be used to replicate any object that it's targeted at and then replicates it without any limit. It can replicate items up to at least the size of a car. It can replicate either one at a time, or a steady stream of the object. Its replicas are not permanent, since if the wand is destroyed, all of the copies created are destroyed along with it. The wand can also be used by humans.
History
This wand belonged to Pearl, however, it became lost over time and is later found by Amethyst in her room. Amethyst, rather than return it, uses it to replicate garbage and puts in Pearl's room. She then allows Steven to borrow it in "Onion Trade". Steven uses it to create replicas of the G.U.Y.S. toy Dave Guy and attempts to trade several Daves for one Ranger Guy.
However, Onion trades for the wand itself and uses it to flood the town with Dave Guys. The Gems try to stop him, but Onion fights back by dropping several replicated cars on Garnet. Steven manages to tackle and disarm Onion. The Replicator Wand is crushed by Garnet after stating, "I'm not cleaning up this mess," referring to the disappearance of all the replicas if the wand is destroyed.
