to answer both of those questions

spinel is NOT a type of ruby, but rather a cheaper imitation for a ruby in real life (it looks like a ruby but isnt)

fusions and single gems only share names, while garnets happen to look similar to the fusion garnet the two are still completely unrelated

(if gem types were all according to the real world ruby and sapphire would be the same type, guide to the crystal gems outright says that they aren't)
