Shadow Milk’s smirk twitched.

Summary
Once upon a time there were four Diamonds who ruled an empire. The most unruly of the four, Pink Diamond, demanded her own world to rule. However, upon discovering the life that existed on earth, the diamond assumed a fake identity and had started a rebellion. After long, lengthy battles between both the crystal gems and homeworld, the war had eventually ended when Pink Diamond faked her own shattering. In their grief and rage however, the three remaining diamonds devastated Earth with an attack that corrupted the remaining gems still on the surface, ending the hard fought war.
Two thousand years later, White Diamond, the supreme ruler of the Gem Empire, had done something both unexpected and thought to be all but impossible. Seeing the gap that Pink's death had caused, White Diamond created an entirely new gem. Now the newest member of the Great Diamond Authority must navigate her way through an empire that's built on both oppression and cruelty. Will her efforts be in vain, or will her presence be the thing that can finally change her society for the better?
A Black Diamond Self Insert.

Summary
Following Bellamy's corruption, he flees Gem society and finds himself isolated on a planet far off the starmaps. After a few hundred years, he's found by an eccentric band of traveling gems, most of which he's fairly sure are fugitives, and essentially adopted into this horribly incompatible group of four (now five). Through Bellamy's eyes, he witnesses these gems' stories one by one, finding these ridiculous figures far more tragic than he would have initially expected. Also, he learns what family is. That's a bonus, I guess.

Summary
Not too different from our Steven Universe that we know. Except for just a few small details from the buildup and duration of the Great Gem War. Blue Diamond might be an integral part of the story 🤭 But you'll find that out soon enough.
Inspired HEAVILY by those fan animations on YouTube (which I watch almost daily because they're so good). My first Work here on AO3, and I am not in any way shape or form an experienced writer. -

Summary
Inspired by Forevermore by OpalizedFossil, I’ve decided to come up with my first fanfic for “Steven Universe” centered on Green Diamond, the daughter of Yellow and Blue Diamond. Like with every OC I come up with, I’ve decided to make a character description to help you see what she’s like, and to use as a reference.
DISCLAIMER: I do not own Steven Universe or any of its characters. They are the works of Rebecca Sugar. This is all purely fanmade.

Summary
It’s been 5632 years, and Commander Jadeite hadn’t forgotten the soldier she sent out to the frontlines in the war against Earth. Day in and day out, Citrine was the sole thought on her mind, so much so that she stopped fulfilling her duty to the Empire eons ago.
When news broke that there were gems alive on Earth, healed from a corruption, Jadeite just had a feeling her fallen soldier would be there.

OC x OC smut, probably one of my favorite works in ages. Has Ruby and Sapphire vibes if that’s what you’re into!
