Pink was a “child” and she needed a servant/caretaker like a pearl to be there. She damaged her first pearl (volleyball), so white gave pink our pearl as a gift. Our pearl was more a combination of the diamonds. In the dress that she wears in the picture it has all of the diamond colors on it.

But No, Pearl does not belong to all the diamonds, the classification is not based on the dress, the classification is based on the color of the stone and its location, and thus the color of the stone is reflected in the color of the physical body that is formed by the magical power in the stone, and Pearl is originally To White Diamond and gave it to Pink Diamond, as for the dress, it symbolizes that Pearl was just a gift from Diamonds to Pink, but in fact, she was the one who made it, White, even the personality and feelings are flawless, she is Pearl, better than the others, like who made her!

Our pearl didn’t belong to any of the diamonds before pink. She was made for pink as a replacement for volleyball.
