So, now that we’ve seen two other Pearls in the show, I was wondering what exactly made the Pearl of the Crystal Gems ‘defective’ as Jasper said. The only major difference I see at first glance is gem placement. Both the Yellow and Blue Pearl have their gems in their chests, while Pearl has hers on her head. But then, it dawned upon me. 

Were those Pearls given to the Diamonds because they share gem placement? Yellow Diamond, Blue Diamond, and their respective Pearls all share gems on their chest. 

Then, I began to realize. Pearl’s white skin. Normal for a Pearl, since common Pearls are usually white in appearance. But, the Yellow and Blue Pearls had colors resembling their diamonds. Then, if you take gem placement into consideraton, well…. There’s only once place to look. 

Did Pearl perhaps work under White Diamond at first? And upon meeting Rose Quartz, decided to change her loyalty and went rogue? 

Probably not but hey it’s a thought lol.
