It's a black hole, the diameter is 0. You can safely assume it's mass.
EDIT: Yes, people who are wrong all the time, I know some report the diameter as being whatever the diameter of the event horizon or Schwarzschild boundary is, but scientists don't, that's not actually the diameter, they'll tell you the event horizon or Schwarzschild boundary diameter if you ask, but they won't claim it's the diameter of the black hole, so shush.)
EDIT2: Yes, I also know it's generally the "Schwarzschild *radius*", but "the diameter of the Schwarzschild radius" just looks bad to me. Again, shush.)
EDIT3: Yes, I know Slashdot doesn't have an edit button... or does it? Could I be testing a hidden feature? Maybe I'm a beta tester for a revision of Slashcode? Or maybe I just right clicked, inspect element, found the edit button, and removed the style="display: none;" tag on it? You'll never know.
