posible coticule, sharp change into an orange layer

[Bram]

Hi, I recently aquierd this litle piece of rock sold to me in combination with two razors, I cleaned and lapped the stone and I'm convinced it is a piece of Belgium Coticule but it transitions into an orange layer which is something I've never seen in any picture of coticules online. so I wanted to show it,

do you guys agree it is a coticule? if you have any other idea about this rock I would realy like to know

first a picture of how it was in the ad


this is how it looked after cleaning and lapping:


and for some extra detail some pictures of the sides (I also lapped the sides but left a couple of sides with the original sawmarks is cause that might help identifying the hone)



and just one more picture showing the stone with one of the razors after I cleaned honed and rescaled it

I have not seen that shade of orange in one but it sure looks like a coticule. Does it produce a milky slurry?

+1 to what Ron just said. Sure looks to be a coticule. Some kind of deposit in the layer that maybe reacted to the moisture it was exposed to when lapping ?

That is a sweet piece of mother nature. How does it hone?

Something that just occured to me, that stone looks as if it is from the hybrid, Les Lat layer. I have seen that color in parts of Les Lat stones.

Nice looking stone! There was a slate mine in Belgium with a couple of layers of coticule in Recht. They were only
exploited during a brief period. But the coloring looks very close to yours.
