To this point, I've only seen one elite recipe, and it was for an armorsmiths. It was a level 300 recipe and for an amazing breastplate. Judging by the items needed to make it though, it seems reserved for the VERY rich (30 bars of arcanite? ouch!). Granted, this was in game, and if you search through the site there might be more and for other professions.
Edit : here's the item in question
