The eased edge for most worktops.
Answer
What is a bullnose edge on Giallo Siena marble and when is it used?
How the edge is finished
A full radius across the face of a Giallo Siena marble piece. It is the most forgiving edge there is, because there is no corner to chip, and the most expensive to produce, because the radius has to be cut and honed all the way around.

Why this stone behaves this way
On a breccia the arris is the weak place, and a bullnose removes it rather than protecting it. That is why it is specified where a piece will be handled — a bar, a counter edge, anywhere a hand goes along it.
What these figures are, and what they are not The price difference is a production fact and it is worth settling at the drawing, because a bullnose is a different machining operation and not a different profile on the same run.
