That could be a line of iron that is/has been transforming solwly into red iron oxide-aka rust.

Rust takes up more volume then iron and exerts a pressure effect.
So a crack mai develop that leads more water in until the all the iron oxidizes.

Also next to the crack on the down right pic...I se a few patchi areas where the colour tends to be grayish-light green/blue...surface pattern seems to disapear over these spots witch makes me belive that thise spots are diffrent then the rest of the stone.

The only thi g that matches the description is coryde quartzite .... that did not have enough pressure or manganase to catalise...
How I see it...

I'm talking about the stria that most Coties leave behind. Its never a highly polished edge. I have four Coties, one seems like more of a cutter, two are about the same, the other very slow and fine. Some like lots of pressure/torque, some don't.
That's the fun.!! Learning each one you have, or mastering the one you have, and finding its potential or your own sanity. [emoji38]

I'm going to play for a while with this stone and see how it works for me. I've just got a little concern that if its a bad spot in the stone (BTW, No blame on the seller) all it will do is cause me problems trying to learn the stone. I dont get a lot of time to play so its time to put stuff away and get ready for bed. In another 6 days I'll get a little more time to play but for now, It time to put my toys away.
Thanks to all for the comments and hoping all will turn out fine in the end.

BTW, I was eyeing that really colorful Coti for sale on the B/S/T thread but I need to hold off on everything for a while. Plus I dont know squat when it comes to these things so I'm not buying. But it sure is a perty rock!

Thanks Jerry, now I'm seriously looking at ANOTHER stone!!!!!

Nope that is one beautiful stone.
Sorry you're having problems with yours my friend. Mine is doing me very right

Yes it is! You know you want it. Buy it man!

The coarser coticules get a nice buffer from using a thicker solution. Can bump performance.

I would pass on the oil if you are thinking of sending it back.
Do nothing to confuse the return....

I happen to like a bit of lather when I touch up a razor. If it feels a bit in need of
a refresh I often apply a bit of lather to a barber hone and give the edge one or
two wipes (hone strokes) rinse, dry and strop. It is amazing how little work it
takes to refresh an edge.

Oil will wash off a coticule with soap and water. He could easily wash it before returning it.

I dare to differ. I once bought a vintage one that had been used with oil. Had to sand the stone to get rid of it. Oil will also get into litlle irragularities and will not be easy to wash or sand out. If you plan on returning it I would not use oil on the stone.
You may want to check whether the slurry stone is the problem. If you have a different slurry stone or a Jnat you could try that one on the coti and see what happens.

In mine I also suspect the slurry stone. I have another one too now and it seems to make a lot of difference
