Besides gem placement, first regeneration outfit we haven't seen yet, peridot saying she looks like a fancy pearl, and skin color, like many fans have mentioned, I've got some more evidence from new episodes to help support the ' Pearl belonging to White Diamond Theory'. Remember in 'Space Race' when Pearl said she had her memories of others worlds and also how she knew about the Moon Base and Pink Diamond's human zoo in later episodes and in 'Adventures in Light Distortion' how she was about to say who she used to belong to she rolled her eyes away and looked very scared and just claimed to serve Homeworld instead. If you look at White Diamonds mural on the moon base and in the old and new Great Diamond Authority logos you'll notice that white diamond has the most colonies and she's always at the top of the old and new great diamond authority logos and in her mural shes holding an orb in her hands ,many people think that this is Homeworld and I personally agree, so this could mean that she is the most powerful diamond and probably governs most of Homeworld. And if we look at Yellow Diamond who has the second most colonies if we remember in message revived when Peridot contacted her and when peridot disobeyed her and called her a clod , and if YD could scare Yellow Pearl and Peridot that easily then, like many fans think, White Diamond could be way worse like way scarier and that could be why Pearl didn't mention her, looked scared and just claimed to serve Homeworld in that episode. And I know what your thinking if Pearl belonged to White Diamond why isn't her hair white, why is it pink? Well I watched a YouTube video by a fan named Rocket Bot, by the way go check
out Rocket Bot's videos they are awesome, called 'Pearl started the Rebellion' he said in 'The Answer' that pearl looked a lot whiter than she does now and I do think that she had white hair. And in 'Gem Heist' when the gems were walking with Holly Blue Agate while she was explaining the zoo's history Pearl at some point during their walk she looked off to the side looking very scared the first time and she looked off to the other side less worried a second time so i think she was just looking around the zoo the second time she was looking around but i think the first time she was looking for some one who might remember her, who is very scary, who probably governs all of Homeworld, who is probably the most powerful diamond of them all I think the first time pearl was looking around she was looking for White Diamond to see if she was at the zoo and was hoping that she wasn't there to see and recognize her as her old pearl. And like how I said that how Pearl had her memories of other worlds, knew about the Moon Base and Pink Diamond's human zoo if WD was the most powerful diamond do you think that like how she went to her colonies to check on progress don't you think that she would have went to the other diamond's colonies to check on progress and also could have went to the Zoo, the Moon Base, and the earth and she could have brought Pearl with her. and remember how Peridot said that Pearl looked like a fancy pearl , what if Pearl had on her first regeneration outfit and had white hair when she served Homeworld and hite Diamond and it makes sense a fancy pearl would make a good pearl for a diamond the highest diamond to be exact who is white, has her gem on her forehead, and governs most of Homeworld. so id think ,like many other fans that pearl did serve White Diamond before she defected to the Crystal Gems and even changed her hair color to make sure that other Homeworld Gems didn't recognize her as White Diamond's old pearl because if anybody found out they could take her back to Homeworld and shatter her.
I have some more evidence from 'It Could Have Been Great' too, remember when the Gems went to the Moon Base for the first time to get the Cluster's coordinates and I think another fan said this but didn't Pearl at WD mural when they first got there and when she was separated from the group for a bit when they were trying to activate the stairs what if she was looking at WD'S mural and when she was going over to the others she had her head turned backwards what if she was still looking at WD'S mural when she was walking before she was turned away by the sudden activation of the stairs and when they were at the top of the Moon Base Pearl was looking out into space. Either she was looking back at earth or she was looking for Homeworld Gems coming here so they wouldn't get caught, or for some Gems that belong to White Diamond and were probably looking for her, or maybe she was trying to keep an eye out for WD herself remember when I said that pearl looked around the zoo a few times but the first time she looked to the side very scared and remember in 'Adventurers in Light Distortion' when Pearl was about to say who she use to belonged to but she looked very scared and just claimed to serve Homeworld instead and remember how I also said that WD could be way more scarier than YD that could be why pearl was looking out of the window in the Moon Base. Anyway I hope you all enjoyed this theory and I hope that the 'Pearl belonged to White Diamond' is proven correct soon.
A big thank you to Rocket Bot ,who made the video I posted, the fan I mentioned in my theory, and of course Amethystkitten for some more supporting evidence and the inspiration to make this theory and to help support her's and all those out there who support the Pearl belonging to WD theory.
