>>104309747You need very specific conditions to produce a gem, and all the evidence we've seen shows they can only reliably mass produce a very limited range of gems. Though that's more of a labbor = demand issue, you're going to need way more shit tier gems like Rubies than you are Sapphires or Lazulis, those you can afford to pour more time and resources into creating because their utility or skill set justifies the expense. Weirdo gems like Fluorite probably occurred naturally once or twice by accident, they studied them for potential applications and if they didn't fit Homeworld's structured heirarchy or solve some existing problem they were either destroyed or they tweaked out the possibility of producing them from the Kinndergartening process altogether.
