You are a Peach Beryl, simple as that. However, you are odd in Homeworld standards. Beryls are small, a key factor; you, however, are tall. And, all you've ever known is that you are used as a knockoff Pearl serving a Sapphire. But, when on the way to a new planet, things don't go as planned, and needless to say, you're life is about to get a whole lot more interesting. Note: I am aware that Rose Quartz is canonically Pink Diamond but when I made this story the two being different characters is what I had in mind.
