I lol'd so hard at this.
But seriously, the white/black crystals are so expensive for a reason. They are arguably the MOST rare color crystals in the game, and they look damn cool to boot. I've drooled over one several times in the "preview" window, before coming to my senses and realized how many dailies I had had to run in order to get the credits to buy it off the GTN. Plus the expac was coming out and I didn't want to clear out my credits for a crystal that would probably be overshadowed by new gear soon enough.
