help identifying this stone... please
i bought this stone.... really know nothing about it other than it is ~5-7k grit....
when dry it is gray in color.... turns dark gray when wet..... the slurry is light grey in color....
it was a bit$h to lap..... i mean harder than chinese algebra......
here are a few photos.... for some reason there appears to be a stain on it.... which i think is where my wife touched it with wet hands before snapping the dry photo....
if needed i can provide better photos....
the stone cuts fairly quickly but seems to be very very smooth....
