We've seen Pearl wield both a sword(s) and spear. She can pull both from her gem, but the swords are always pulled from storage, while the spears are created from light, the same type as her body mass. Garnet's gauntlets and Amethyst's whip are also both of light/gem produced material. Rose's shield is of the same light material, but her sword is a physical weapon like Pearl's many swords. There were also a number of gem weapons on the Strawberry battlefield, obviously physical weapons as well. So what does it all mean? Why do some gems use summoned weapons, while others use physical weapons? Why do some gems switch between the two? Check out the theory below for some answers. This is definitely one of the more solid theories I've heard recently.
