here are some more interesting views. notice the chipped area has some translucence to the top layer

Unless it's just my screen, I don't see any translucence. I see whitish areas, but not translucence. We're all just looking at a screen though... much easier to say for sure when seeing it in person.
Yeah that picture is not as good as i though it was...
maybe ill shine a flashlight in the stone and take some pics to show it a little better.
I am adding myself to LI believers.
Some JNATs are very slow. Your stone looks like hard asagi. Try sharpen something bigger like chisel, knife or kiridashi. And use stone with thick slurry. That makes very black slurry (steel swarf).
LI stones are hard stones and fast sharpeners without slurry usually.
LI and JNAT differ in how fast they absorb water along the sides. JNAT absorbs water faster on the sides. It's slate. This could be a good test.
