Gem-Ready Steven Universe Props for Halloween & Cosplay
Putting together a Steven Universe costume that actually works, for Halloween or a con, doesn’t need to cost you your entire gem stash. Whether you’re dressing up your little sidekick for trick-or-treating or preparing for your next cosplay appearance, we’ve got the perfect sword and shield to make your outfit shine brighter than Rose Quartz’s gem.
Which Size Shielding Your Style?
Our Steven Universe props come in three size tiers, because heroes come in all sizes — from small but mighty, to full-on gem warrior mode.

PETITE (For Heroes Under 5ft)
- Sword: 17″
- Shield: 14″ diameter
- Light and super manageable for younger fans and trick-or-treat pros.
CONVENTIONAL (Cosplay-Ready)
- Sword: 23″
- Shield: 17″ diameter
- Scabbard included to fit the sword — perfect for conventions and photo ops.
X-LARGE (Full Gem Power)
- Sword: 31″
- Shield: 23″ diameter
- Scabbard included and ready for epic entrances (or boss battle poses in the hallway).
All props are made of lightweight wood, so you or your kids won’t be dragging around heavy gear like it’s a real boss fight.
Want to Save Even More? Go Unpainted

Here’s a tip from a fellow cosplayer on a budget: go unpainted. Our Steven Universe swords and shields come glued, pinned, and ready to paint, straps and all — no guesswork required.
Customize your props your way, and keep your budget intact. It’s a fun weekend project, or even a bonding moment with your mini-Steven or Connie.
