Daughter of Blue Diamond (Reader insert)

Part 2

A few years have passed and (Y/n) is the age of 15. She now lives with her new mother, Blue Diamond. She's now closer to her pearl as well. When Blue adopted her as her own daughter, she was introduced to Yellow Diamond, her new aunt. In Homeworld, a lapis lazuli terraforms a small part of land to make water for (Y/n) and to plant a fruit tree for her from the zoo for her to eat.
But not everything will be perfect, a sapphire saw in her future vision that (Y/n) will have the illness that killed her parents. Fearing for her daughter's life, Blue Diamond tries everything in her power to prevent (Y/n)'s death. She lost Pink and she can't afford to lose her daughter as well.

Days have passed and (Y/n) was beginning to feel weak. She could barely stand or walk. Pearl tried everything she can to comfort the daughter of Blue Diamond.
Later that day, Blue went to go visit her daughter in her room. (Y/n) lays in her bed. Sweat falls from her face. When she saw her mother coming closer, she reaches out for her gigantic, blue finger for comfort.
"Mother, I don't feel so good." (Y/n) softly said.
"I know, my little one. I'm trying everything to cure you soon." Blue Diamond replies.
More days have passed and (Y/n) is still getting worse. She sweats more, having trouble breathing, and she can't take anymore pain from her body. Yellow and Blue were in her room trying to comfort her. Yellow Diamond tries to explain to Blue that (Y/n) isn't like them and she won't make it. She could die from her illness.
"I'm sorry to say this Blue, but she won't be able to make it. I think it's time to let her go." Yellow tries to explain.
"No! I won't allow it! We lost Pink and I can't handle the thought of losing my daughter too!" Blue yells.
As they both continued to argue, a coughing fit had stopped them from going any farther. (Y/n) was on her side coughing rapidly. She looks up at her mother and her aunt. Even in the back of them, their pearls are worried for the young human girl.
"Mommy, Aunt Yellow." (Y/n) calls out to them.
Yellow using her finger to stroke her niece's hair while Blue's finger is being held.
Out of nowhere White Diamond's pearl had showed up. "Yellow Diamond, Blue Diamond. Both of your presence is required. Along with (Y/n)."
Both of the Diamonds were in shock that White was calling for all three of them. White's pearl lead them back to White. As they reached their destination, White Diamond was stand by the entrance looking radiant, yet terrifying at the same time.
"Blue, Yellow. You came. And thank the stars you've brought little (Y/n) as well. I've heard that she wasn't feeling well and I believe I've found a way to save her."
"Will it save my daughter's life, White?" Blue was worried for her daughter's life.
White Diamond gives her a toothy smile, "Of course it will. My idea is to turn her into a Diamond like us."

White Diamond explains that she'll need a piece of Blue to make (Y/n) into a Diamond. She cuts a small piece of Blue's hair and begins the process. White places the hair on (Y/n) chest and hair. A blue glow forms around her nearly blinding everyone one. As the glow began to fade, all three Diamonds could see (Y/n) has changed a little. She had a blue diamond gem on her chest, new clothing, and her hair was all blue. She opens her eyes saw all the Diamonds surrounding her.

Blue gently take (Y/n) in her hands and held her closer to her cheek. Tears were forming from both of their eyes. Tears of joy.
White Diamond smiles at the other Diamonds then announces "There we are, she's not longer (Y/n)the human, now she is (Y/n) Diamond. Welcome to the Diamond authority, little blue."
