It occurs to me that we don't know for sure every Gem has a signature weapon they summon from their gemstone. Lapis Lazuli fought exclusively with her OP hydrokinesis powers. The only thing she appeared to summon from her gem was a pair of waterwings. What if that's only something "Gem Warriors" like the Crystal Gems train themselves to do? There could be other "gem classes," like a "Gem Mage" that fights just with magic like Lapis. It's not that far-fetched, considering Rebacca's love of RPGs. Peridot might just be a regular maintenance guy not even trained for combat.

That said, if we're assuming she does have a weapon, my vote goes for something utilitarian like a big spanner. Something she could use to make repairs when she doesn't need to defend herself.

If she's more of a gem mage like Lapis, I'd say her specialty is healing magic or illusory holigrams.
