Magic in this show comes down to pocket dimensions, FTL tech, lasers, which are all technology we can imagine but don't comprehend. Steven's bubble is simply a hard light projection (In "An Indirect Kiss", Amethyst becomes glitchy after her gem cracks and her image becomes fuzzy before it glitchs) like gem bodies or what can be called a force field. Fusion is the combination of the characteristics of the hard light projections produced by 2 or more gems to make a stronger entity  which would require a sufficient amount of cooperation and energy to maintain stability ( The gem stones themselves do not fuse, only the projections do). Gem tech is powered by gems so it could be said that they generate and store a massive amount of energy which can be used to generate their weapons (The more gems you have the more energy, themore energy you have the stronger the fusion). It can be explained as technology so can it really be called magic? Peridot has been shown to understand the items and devices on the show as tech so are those who don't understand it (humans and the exile crystal gems) really a reliable indicator of magic vs. tech.
