Thread: Identifying a random Japanese Natural stone

Hi guys- I bought this stone last week. It's 3"+ by 7" It's a waterstone puttied into an old pine base. It leaves a hazy mirror finish with scratches in it. Is it possible to identify a stone like this, or should I just leave well enough alone? I am assuming that its Japanese and it slurries relatively easily. The black is in the stone and doesnt seem to affect anything.

looks like a Jnat, but it has to be lapped and the sides cleaned to tell for sure.
Just by looking at a Jnat it is impossible to say what the mine or strata of origin is.

Stone is pretty much lapped... Its got a ding and a nick, etc in the surface but im not going to lap 1/16 off of it just for that. Ill scrub the sides down in a bit...

can you take a photo with slurry on?

Here is slurried. i did it with no pressure with a very worn blue DMT it was a little reluctant to give it up but not nearly as hard as a soft arkansas

Also can you also post a pic of the cleaned side?

I think what you got is the canadain stuff.
There are alot of them floating around.
It slurries and takes to water very nicely.
My has alot of cut to it. and a nice smooth edge.
so you did get ya self a nice stone.
bummer my flash changed the color of
the slurry somehow.

I have got a magog theyre a bit different in color and grit but i dont have enough experience to say with certainty that they are not the same stone

There is no label... The stone is very fine and it looks exactly like labeled stones however - so I assumed it was Magog.
