Treads, risers and stringers from one stone.
A staircase is the one element people touch, tread on and look up at all at once.
Treads and risers
Cut as a set, matched across the flight.
Treads and risers cut from the same block run the pattern up the flight instead of restarting at every step. Granite is the specification here: a stair is trafficked, and engineered surfaces are not rated for it.

Underfoot
3 cm treads, textured nosing.
A stair tread spans unsupported and takes concentrated load, so it is the one place we always specify the thickest slab. A honed or leathered surface gives grip where a polish would be a hazard.
