<p>So considering Pearl's color scheme, let's guess she was either white diamond's, or just a generic pearl. Let's assume when Rose said "My Pearl" she meant it literally, as in she owned Pearl. That makes Rose either a very powerful or special quartz.
</p><p>Considering she's easily Jasper's size or bigger, and Jasper was supposed to be an increadably big and strong gem, even among quartz, that probably means Rose Quartz was very powerful as well. Now consider the search for Jasper; why is recovering her so important to the gem homeworld? Either her power is so well respected that she has special privilages, or there was something special about gems made by Pink Diamond. If this is true, maybe anouther one of Pink Dimond's gems was special enough to warent getting their own Pearl.
</p><p>It's possible that Pink Dimond didn't even make her, though, considering we believe Pink Dimond's only colony was earth, and we know that Rose Quartz was from space. Maybe she was a famous quartz who had already helped to take over another planet. That would also exsplain why she would have her own Pearl, and why she would be sent to earth to help Pink Dimond make her first colony. Plus, this exsplains why Rose would want to protect the life on earth, since she had already seen a planet destroyed by the gems, and didn't want it to happen again.
</p><p>But then again Bismuth said Roze was made "Right here in the dirt" so maybe she was made on Earth. This would certainly lend to the Pink Dimond making special gems theory.
</p><p>Either way it's quite possible that Rose was given Pearl. And if Pearl belong to Rose Quartz, a member of Pink Dimond's court, that would certainly explain the pink dimond on her uniform.
