First off, neither he, or any other Dark Elf, created the Aether. It is the Reality Stone. Odds are a long time ago, one or more Dark Elves found it and turned it into its present state so they could use its power. Whether or not it and the other Stones have more forms is debatable and likely won't be answered until the Infinity War movies. But to be used by the Infinity Gauntlets, they will have to be smaller and gemstone-like.
