Polishing
From sawn to mirror — the grit ladder that brings out a stone's face.
Polishing is just scratching — finer and finer scratches until they're too small to see. The grit ladder goes from 50 to 3000, and skipping a rung is the one mistake you'll never recover from.
The ladder
50–120 grinding, flatting the face 220–400 honing — the scratches start to blur 600–1200 satin to semi-gloss 1500–3000 mirror, only on dense stones
The trick
Change grit only when every scratch from the last one is gone. Water, patience, and a flat lap — polish is 10% skill and 90% refusing to move on too early.
