Biography
Early life
Krystal Sapphire Diamond was born in Olympia, Washington in July 18, 1999 and is an only child of Roark and Sapphire Diamond. Her father is a doctor and her mother was the star volleyball player who later became a health and fitness trainer and educator after Krystal was born.
When Krystal was fifteen years old, Sapphire died of cancer after fighting it for five years. Her death affected Krystal and Roark pretty hard and they slowly do their best to adjust their lives without Sapphire where Krystal took over her mother’s duty around the house. After her death, Roark got a new position at a hospital where Carlisle Cullen works in Forks so he and Krystal move there leaving Krystal to say goodbye to her best friend Anna Reed.
Krystal transfers to Port Angeles High where she meets Carly Jensen, Nathan Dallas and Danielle Olsen who all became her best friends. Krystal also meets Miley Ray, a diva at the school, who became her tormentor due to Krystal’s attention from a lot of boys and to Miley’s displeasure; Krystal is not bothered by her.
The Other Half & A Reason To Smile
Lucas and Krystal.
"Remember how I said that my life is complete, well now my life is complete."
- ―Krystal
In The Other Half, the story was narrated on Lucas Stone’s POV where he became Krystal’s mate while A Reason To Smile is on her POV. In those stories, Krystal starts her junior year in Port Angeles High. At the start of her new year, she meets Lucas and instantly falls in love with him as Lucas returns the same feelings for her. On the second day of school, Krystal asks Lucas out to lunch, which was answered by Emmett Cullen, and the two of them start to get along since then. However, Miley also shows to be interested in Lucas but fails to get his attention and kidnaps Krystal in the bathroom and beat her up with her friends until Lucas, Edward Cullen, Rosalie Hale and Bella Swan came being warned by Alice Cullen and saved Krystal getting Miley suspended. After Carlisle aids Krystal, Lucas confesses his feelings for Krystal as Krystal returns the same thing. In The Other Half from Lucas’s POV, Lucas comes into Krystal’s room to watch her sleep unnoticed to her and hears that Krystal loves him. Later on in the stories, Lucas asks Krystal out on a date and the two of them spend time together at La Push beach. During that, Lucas took off leaving Krystal behind. Curious, she followed Lucas to see him hunting a deer and drinking its blood. When Lucas was caught and told Krystal that he’s a vampire, she said that it was ‘cool’ much to his shock.
Krystal finds out Lucas is a vampire.
Krystal learns more about Lucas and the Cullens and the world they live in making Krystal fall in love with him more as she meets his family at their home. A few weeks later, Krystal received the news from her principal Mr. Fulton that Roark was killed. Because she has no other living relatives, Krystal has to transfer out of school moving to New York to live with her godparents Miranda and Adam Knight which Krystal refuses to be away from Lucas. Luckily, Carlisle and Esme Cullen offered to be her guardians so that Krystal can stay in Forks. After hearing the news about her father, Krystal hears from Lucas that a vampire killed Roark and someone is after her so the Cullens moved Krystal out of her home into theirs for protection. Two weeks have past and so far the Cullens found nothing. While Lucas was arguing with Emmett, an army of newborns ambushed the Cullens and they appeared to be after Krystal but the Cullens destroyed them until Lucas and his family and Jacob Black passed out which is impossible for a vampire, and a guy appeared taking Krystal’s energy and kidnapped her causing Krystal to pass out.
Krystal wakes up all tied to a chair and meets the guy who kidnapped her. He reveals himself as Jonathan, a hybrid who knows about her and the Cullens from Miley who is now a vampire. She reveals that she was the one that killed Roark and agreed to help Jonathan to get rid of Krystal for what Lucas did to Olivia, his mate (unaware to Miley that Jonathan’s using her until later). With Miley’s gift to erase the Cullen’s memory of what happened to them, Miley and Jonathan have enough time to torture and slowly kill Krystal for Lucas to feel the pain Jonathan went through. However while filming Krystal being tortured, Krystal spit into Miley’s eyes causing her to complain leaving the room with Jonathan behind her. Given a chance, Krystal was able to cut herself free and was about to escape until Jonathan catches her and breaks her leg while draining her energy. Just when Miley is about to kill Krystal, Lucas comes in and stops her and Jonathan. Lucas starts fighting Jonathan and Miley but is at a huge disadvantage due to their gifts. Just when Lucas was about to have his head ripped off, Krystal distracted Jonathan and Miley by cutting herself drawing blood out giving Lucas enough time to break free until he caused a fire and Jonathan threw Miley in it after going against him when Lucas told her that Jonathan’s using her. Lucas was just in the air with Krystal in his arms when Jonathan yanked him down causing him to drop Krystal where she hit her head to the ground. She was supposedly dead until Krystal brought herself back to life but just barely giving Lucas the chance to change her. Three days after the Cullens killed Jonathan and Krystal’s transformation, she awakens as a vampire. Lucas was there when she woke up and took Krystal out for her first hunt which she messes up a few times. After her hunt, the Cullens welcome Krystal into their family and became a part of their coven.
A year later, Krystal graduates high school and Alice threw a party at their house. After the party ended, Lucas took Krystal outside where he proposes to Krystal and the two are now engaged.

Unfortunately, the two don’t know where Joham is and they’ve been destroyed afterwards.

Joham, however manage to take Lucina without getting touched by Tiffany and escape only to find out that they wanted him to do that since they were aware that Joham knew about Tiffany’s gift by the real Blake who escape and the Cullens burned a exact replica of him. With Lucas’s aura around Lucina to take in the drug that Joham inserted in her, Tiffany was able to see through Lucina’s eyes and find Joham. Just when they were about to destroy him, the Volturi arrived who heard about the newborn army. They meet Tiffany and Lucina and Aro eagerly offered them to join their coven after hearing about their gifts, which was refused by an angry Lucas. Lucas made them open their eyes about their jobs and the wrongs they did and to do it right. Soon the Volturi burned Joham and left the Cullens and the pack and Edward said that Lucas made the Volturi see the truth although it’s gonna take awhile for them to admit it. Soon everyone expressed their gratitude to Lucas for being a part of their lives where Krystal expresses how her life would’ve been like if she hadn’t met Lucas and cheered for him.
