Identifying natural stone

Hello to the board, I trust everyone is well.

I found this stone in my father's garage, I think it came from his friend's brother who passed away and was a craftsman of some sort.

Any ideas what kind of stone it could be? Hard to judge precise fineness, I haven't put a razor on it yet, but it feels pretty fine. It slurries easily to a fine light grey slurry, and is fairly soft, it was easy to lap some deep scratches out of it. I am in the UK, and the stone is 8" x 2" x 1"

Grateful for any thoughts!

I've seen Charnley Forests that are like yours, I'm no expert though.

I'm sure the experts will come out of the woodwork soon! It is a distinctive looking stone, so perhaps someone has a view.

That one front view almost looks like a washita but if it slurries then definitely not. Nice looking stone Monty. I'm eager to hear how it works into a progression.

Yes! It is a nice looking stone. My feeling is that it is a pretty fine stone, but perhaps not a finisher. Let's see...

Thats a Dalmore Blue Stone, most likely around or comparable to a 5K Stone

Many thanks, after a quick web search, that rings true. I have not put a razor on it yet, but did try a kitchen knife, and my rough feeling was 4-6k, so that adds up.

Mystery solved!

That might be a great addition to a progression. It seems like naturals are less often in the middle, at least the ones I run into. Normally finishers or too coarse for razors is what I seem to find.
