Thread: Help ID the "Gnomestone"

My friend Darl (Tarkus) shared a find of three stones a while back here. He found this hone and a labeled Escher as well as a smaller one seemingly an Esher. He gave me this stone. (THANKS, Darl!) I jokingly told him if it was no good, I would put it in my flower garden and set a gnome on it.
After much joking it took on the name of the Gnomestone. We compared the flattening effort to the Eschers, seemed the same. I have no experience with naturals other than playing around with a Coticule. I have finish-honed 2 razors on it after my usual progression, substituting it for my usual Naniwa 12000. It felt awesome. I could tell it was really getting sharp and the bevel is super shiny and smooth. I will shave test these razors tomorrow to see what I have in a finish. The sides are rough sawn and irregular. It has a light gray surface with darker gray splotches.
Any Ideas what the Gnomestone is?
Thanks,
Tom
