6500 grit is about 2 um depending on whose numbering system you use.

As you say that's a bit too coarse for diamond because of the deep, "crisp" scratches they leave. I usually go to 0.5 um on diamonds for that reason, whereas I think that 1 um is perfectly fine for AlOxide. SiOxide can safely be even more coarse than that IMO.

As Brian says that is a very nice and uniform edge. I think it's a good example of "maxing out" the media, by which I mean that it's been thoroughly worked with nothing missed, and there probably isn't anything you could do to improve it without using finer abrasives.
