Thanks this was indeed very helpfull. So the only way to get those crystals is by buying cartel pack? Any of the 2 in particular?
I only bought the Crime Lord (the bigger one) and so far I have three of them. The odds of the bigger one are bigger than in the smaller one. Also, I tried to put one on the GTN but that seemed like it wasn't possible (did it after two days because of the timed binding rule) and I also haven't seen them appear on the GTN, so I think they're only obtainable with the Packs.
