I determine hardness through lapping! I'll get the sizes tonight!

It has a very smooth and creamy slurry texture that darkens fast - coticule like .
Nice stone - they are very consistent stones .

Marble.
Texture doesn't look like belorechit.
Too little pyrite.
Belorechit has another type of crack surf

I'm still currently testing this stone but as a interesting side note my original seller seems to be selling a few more [emoji53]

As for my current test I feel that the current stone doesn't remove any steel. But I could be wrong.... original eBay listing was (eBay uk) 262869735650 if anyone wants to see it.

Thanks for sharing, it looks like marble to me too.
