Yes, Diaz is a black belt, and a legit, solid one at that. The guy he is facing is a truly world class champion black belt. Let's pretend that there is such thing as a "striking" black belt. Some dude who trains for 10 years and is damned good is a "striking black belt" legitimately (I would call most mid to upper tier UFC fighters with "good stand up" a "striking black belt" for this analogy). He then steps in to fight Anderson Silva...
