I might shed some light into that riddle here, actually i have to search thru my Escher Database to give some details.....

Well had to do a bit of search, as Hatzicho already mentioned i would guess that it might be a synthethic stone....
i found those Pictures of the "Ideal" and "Perfect" Razor hones, which showed the same Artwork, or nearly an identical artwork, i dont remember where i have seen those in one of the old catalogues...all are advertised with the old silver Medal from 1903 Linz and 1903 Hannover and all have the "usage with oil or water" printed on the instructions....actually the stones themselves look less green and to tend to go more into a brown color.
