Everyone knows that a gem needs light for energy, but what if darkness can make a gem lose their colour? White Diamond's pearl probably went to that chamber where Stevonnie was placed in by Yellow Diamond. Then after White Diamond switched her original pearl with Pink Diamond. Afterwards, she complicated her commands on purpose to break her, then cracked her gem after she broke. Once she cracked up, White resurrected her but the gem stayed cracked, which is why her face is heavily damaged. Afterwards, she started to control her new Pearl. She might have done the same with other gems, which is everyone fears her. What do you all think?
