Opinion on this hone please.

Hi i got this hone a little while ago i like it and think its a turkish oil stone but am not sure i have a stone that is a turkey and it is a lot browner in colour with more pronounced fractures through it ,This stone is blacker with bands of speckles through it but being natural stones i am sure they can vary a bit the stone measures 130mm long by60mm wide and 30mm deep puts a great finishing edge on a blade with thin oil.

These Turkey Oilstones come in all sorts of colours.

It is a Turkish oilstone, I also bought another one a few hours ago :p. One of the fastest stones I know, works as a finisher, but not the finest finishers. Use it only with oil. If it's too coarse, lap it until the surface becomes as fine as possible. May I ask how much you paid for it?

Thanks for the input guys ,as for price i will tell you because i do no not think it reflects its true value i bought 3 stones in a lot but this was the one i was most interested in because of the odd size and it does have a box but no lid and the box is well made and finished on the edges so i paid $6.50 aus for them all the other two turned out to be man made stones on is a double sided stone and the other is very fine and hard brownie yellow coloured stone.Imay post it later just to see if any one knows anything about it.I think there may have been a few turkish oil stone made there way over here as its the second one i have.

Great $ for Old Turkey.

Turkish oil stones come in a range of colors and grits. Do not drop on a hard surface or they will shatter. You may want to seal that fissure. They are great natural stones that should find a place in a honing progression. They are fun to test.

Actually, they are white. the darker parts of the stones is really light blue. If someone submerge them in oil, then they become black and stay this way forever. Supposedly, the darker the color, the coarser the stone, but it's not always true.

Yes. To illustrate, two hones before and after cleaning:

And two pictures to illustrate both the colour differences and the brittle nature:
