y’know speaking of things that are clearly important and haven’t been addressed yet

i remember a while go people were speculating whether this large blue gem (and the white one from serious steven) were diamonds defeated in the war. obviously we know now that’s not the case. but, like, who are they? 

they’re obviously SIGNIFICANT, but haven’t been addressed since they got bubbled. they’re notably larger than the average gem, too. although, now, we’ve seen someone of about the same size… 

the other significant difference with the blue and white gems here is that they inhabited and could manipulate structures/environments. is this something all gems could do if trapped in a building, or only larger ones like these? we’ve seen a gem trapped in a pillow that could create pillars out of sand, but that might be more akin to lapis controlling water while inside the mirror - a gem that can manipulate an element. otherwise we’ve only ever seen gems become corrupted monsters (and it seems very clear by now that corruption is different from trapping a gem in an object.)

so, yeah! if these ladies aren’t diamonds, who are they? is there a link between their inhabiting buildings and bismuths being architects, creating structures? or are they only related by size, with these two being larger, specialized gems, but in totally different ways?
