The guy who built my barn used a diamond blade in a circular saw. The
cuts
were nice, and barely burred.

I don't doubt that, but the diamond played a small role in the cut.
Diamond at high temperatures dissolves into steel readily-so in fact they
were more likely friction sawing than anything. You can accomplish the
same task with a fine toothed blade running backwards.
