My Explanation on Why we haven't seen White Diamond

Perhaps, like Blue Diamond, she's so emotionally distraught from Pink's shattering that it's extremely difficult for her to do anything she's supposed to do. Due to her emotional state, her court has begun to break down as well.This is what this theory would imply. Her kindergartens would start to stagnate and not produce gems, her hierarchy would start to break down due to a lack of leadership, gems would be traveling the galaxy working far less because of this as well. This would also explain how we have not seen any gems in WD's court yet, because the leadership is nearly lost. BD and YD's court are only ones actually capable of carrying out the work the gems species needs. BD, though emotionally distraught, is still taking some care of her gems. This is why YD is so headstrong about moving on from PD's death, Their government is collapsing. YD can still help BD move on and get some things back in order, but YD is feeling like they need to move forward quickly, or their government will truly break down via /r/stevenuniverse http://ift.tt/2rqFrQK
