Larry, regardless of what Herane's guys said, there is no way the pen blanks are E.I. rosewood. The end grain says that's impossible. As nearly as I can tell, it's probably Brazilian rosewood, although I'm not 100% on that.
Here's a typical end grain of E.I. rosewood, then the end grain of the pen blanks, then a typical end grain of Brazilian rosewood.

I can only assume the Hearne guys don't understand wood anatomy and have based their statement on the face grain. I agree that the face grain suggests it could be E.I. rosewood but I don't have any samples of E.I. rosewood that look quite like it, whereas it looks exactly like a piece of Brazilian rosewood that I have.
At any rate, ID via face grain is reasonably accurate SOME of the time, but end grain is MUCH more reliable all of the time and as you can see from the pics, it's quite distinctive in this case.
