New Girl On the Block

Here's Pink Diamond, new to the neighborhood near her college. At this point, I don't fully know the relationship between her and the diamonds so I made a story for this based on the possible "Pink Diamond's like the little sister" thing. In this made up scenario, the Diamonds are siblings in the Diamanda (meaning diamond) family, from oldest to youngest:
Bianca, Amarilla, Skylar "Sky" and Rosaline (White, Yellow, Blue and Pink)
Rosaline (called Rosie by her sisters, much to her annoyance) moves in with her sisters after graduating high school and coming to their college, wondering what she wants to major in.
Side notes: Blue majors in Creative Writing with a minor in Photography, Yellow majors in Business with a minor Design so she start a line of fun strategy games (with help from her far-more-fun-to-be-around-with little sis) and White majors in both Psychology and Social Sciences (with help from Blue, she hopes to write a book that helps with deal with things like depression.
