So I think it’s about time I start writing up a compilation of all the possible weapons that could result from Rose or Steven fusing with the other crystal gems. Let’s start off easy.

The Temple Gem (Cubic Zirconium?): Sword



As many of you know, the temple gem is in fact a depiction of the fusion between all four crystal gems (for those who don’t: rewatch the pilot, her gems are in color there). What many don’t know is that beneath the waves north of beach city is a sword that broke off from the statue many years ago. We’ve only seen it twice: once in Bubble Buddies and again in Ocean Gem.

The blade comes from pearl’s spear, while the grip and pommel are from amethyst’s whip. Garnet’s gauntlets from the cross guard, but this gem fusion is only possible because the three are bound together by the symbol from Rose’s shield. This is why Alexandrite doesn’t have her own weapon and why she is so monstrous compared to the beautiful and humanoid temple gem: Rose Quartz was the glue that bound the crystal gems together!



(kudos to the anon who pointed out the composition of the sword)

Note: From here on out, all gem weapons are speculation based purely on the possible combinations of available weapons.

Rainbow Quartz: Parasol

While it may seem like a silly choice for a weapon, umbrellas have a rich history of weaponization both in fiction in real life. It was heavily used in the martial arts styles Hung Ga and Bartitsu (the primary martial art used by victorian gentlemen too stuffy to giggle at the name). Fictionwise, it’s also the primary weapon Neo from RWBY and The Penguin from Batman

Based on the fan art, the fandom at large appears to have concluded that Rainbow Quartz’s weapon was a battle axe but in my honest opinion, a parasol seems more faithful to her design and theme. That plus I have a battle axe in mind for someone else.

Rose + Amethyst: Flying Guillotine OR Yoyo

The legendary Flying Guillotine, which has been used more extensively in fiction than it ever has in real life, is simply a bladed bowl or hat on a rope that was supposed to be able to decapitate anyone with single throw and bring back their head. In this case, Rose’s shield would grow thorn-like serrations on the edges matching its decoration and would probably bring back the victim’s gem

Alternatively, The the weapon in question could be a yoyo, which according to urban legend was originally used by Filipino tribesmen as a weapon. We normally use yoyos as children’s toys, but given that both possible fusions involve a smol child (thanks to Lil’ Amethyst) it’s an oddly appropriate choice of weapon.

As many of you may remember Rose’s shield creates vibrations when struck, capable of disrupting gem constructs like Pearl’s holograms or Lapis’s water clones. This additional power would turn a relatively weak yoyo into a tool of destruction!

Rose + Garnet: Cestus

Cesti were an early form of boxing glove used by roman gladiators. While gauntlets and boxing gloves were designed primarily for protective purposes, cesti branched off from the family to become weapons reinforced with (often spiked) steel plates. In this case, Rose’s shield would become the thick plate and might manifest spikes in the form of rose thorns.

As I mentioned above, the shield’s vibrations would also be a powerful addition. This is where the Cesti would diverge from Garnet’s already powerful gauntlets

Rose + Garnet + Amethyst: Sling

Don’t let it’s low-tech construction fool you. Slings were fantastically powerful weapons in the right hands, potentially having more piercing power than an arrow, and sling bullets weren’t exactly hard to come across: any pebble would do. Of course, this fusion’s sling (featuring Rose’s shield as the pouch) would use garnet’s clenched guantlets as a rocket-propelled bullet capable of immense devistation

Rose + Pearl + Amethyst

Like the previous weapon, Amethyst’s whip would serve as a pair of bands while Rose’s shield form the pouch. Together with Pearl’s spear, we’d end up with a fairly nasty slingshot. Note that the slingshot would use energy bullets similar to Opal’s bow due to the lack of Garnet’s guantlets.



People who often forget that, like slings, slingshots were actually pretty decent weapons. A bow’s accuracy and ease of use alongside the ubiquitous ammunition of a sling created a match made in heaven. Unfortunately for the slingshot, rubber bands were invented in 1845, over 500 years after the invention of guns.

Rose + Pearl + Garnet: Battle Axe

Sorry, there’s a reason I’m a fan theorist and not a fan artist. As far as weapons go, this is the one I’m not sure about. I’m certain we’ll se a battle axe at some point, but i’m not sure if this will be the fusion who uses it. Granted, we’ll probably never see this fusion to begin with, but all the same it’s fun to imagine

Bonus Weapon

Yellow Diamond: Sword

For symbolism alone, Yellow Diamond wielding a sword seems the most obvious choice. Just as Steven’s shield is a symbol of his desire to protect, a sword is the oldest lasting symbol of war. Swords were the first tools made exclusively for killing other humans, and at no point would they become the last. It’s brilliant because it not only draws a contrast to Rose and Steven, but also because it draws parallels with the temple gem, who I believe to be Cubic Zirconia. It’s also pretty inevitable that a diamond would have a bladed weapon, since diamond’s fabled hardness actually refers to it’s ability to cut
