What are Gems? (Scientific Analysis)

Today I go back to my roots! We are looking at the fictional race of aliens from the animated TV Show, Steven Universe: the Crystal Gems! I will try to classify their culture as well as their anatomy, traits, and bodies through scientific examination and speculation! I will try to answer questions like: What are they made out of? What don’t they need to eat? How do they work? Are they robots? And lastly: What they really are? By using Science!!!

We talk about everything from the Kardashev scale, to nanomachines, aliens, to, surprisingly, crystals!

Hope you enjoy!

Let me clarify: My theory might not fit the show 100% entirely, as it should. My theory is simply a scientific speculation and classification of Gems as if they existed in our Universe and had to follow our Universe's laws and rules. Due to this, the very nature of a fictional show with fictional rules will most likely contradict my real life speculation in some aspects. Just remember, I'm trying my best and I understand Steven Universe has magical elements that might not fit within real life scientific explanations.
