I'm sure that whatever they end up doing it'll be cool ^^. Was nice talking with you

We don't really know if they had a creator or not, but yeah. Still, fiction's full of examples of artificial intelligences developing emotions, so perhaps that happened with the gems too. Maybe we'll find out someday.

We can't really know for sure. But, if somebody else created the diamonds and the other gems, perhaps that person (or species) liked the idea of making them look the way they do. Still not seeing anything illogical here.

Well, if the Gems' creators were the Diamonds (who all look female) then it doesn't seem unusual for them to make female followers. And really, you don't need a justification for them all looking female any more than you would need a justification for making them look like robots, or any other more generic sci-fi alien appearance. It doesn't affect their ability to do their jobs one way or another, and they have to look like /something/. So again, we return to the question, what should they look like?

Firstly, where did you get this "sole purpose is conquest" thing? We've seen plenty of gems who aren't designed to fight or conquer anything. And even though war is extremely important to gems, there are tons of jobs in any military that don't involve fighting. As for the gems' emotions, I can only infer that they aren't capable of designing intelligent gems that don't have feelings. Finally, even if every gem is designed for combat, I see no reason why it would be somehow illogical for gems to look like women.

The elites have emotions and can appreciate aesthetically pleasing things, so they presumably prefer good-looking servants to less good-looking servants.

Not all of them, as Pearl proves. And military organizations pay a great deal of attention to cosmetic details, like how you wear your uniform, your posture, how you salute a commanding officer, all that stuff. Doesn't seem all that ridiculous for gems to do the same even down to the appearance of their troops, since that's a thing they can control.

For the heck of it, and because their culture seems to value strict attention to detail, which often goes hand in hand with caring about appearances and presentation. Isn't that a big plot point with Pearl, how she was designed to be pretty and a status symbol?

What's to say inorganic aliens can't have an appreciation for aesthetics?

What should they look like?

I don't see why this would refute my idea. They're just behaving in ways that seem natural to them, and humans (including the audience) perceive those behaviors to be feminine. Aliens looking and behaving like women really isn't any more far-fetched than aliens looking and behaving like giant bugs, or whatever other concepts are more common in sci-fi.

If you want to get really particular about lore or whatever, why do all the gems speak English? It isn't just Garnet and the main gems who do, it's every single one, even those who have never been to Earth at all. Now, if you want to explain this away, you could hypothesize that gems have some sort of built-in feature that translates everything they say into the language that the listener understands. This would make sense for a race that operates on a galactic level, colonizing, conquering, etc. If this is the case, then the gems all using female pronouns could just be an artifact of how the English language works. People traditionally refer to themselves with pronouns, and out of all the options, that label most accurately describes /to humans/ what gems are. It's true that an alien warrior race might not really have any use for the concept of a gender within their own society, but when interacting with humans, who fixate on it and use it to determine how they interact with people? Very important.
