posible coticule, sharp change into an orange layer

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 :beer1:

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 ? :thinking:

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.

Man ! That looks good enough to eat ! :rofl2:

That has to be a coticule, nice one. I have something similar on a coticule of mine but with a pink bottom layer.

What wood did you use for the scales?

In my humble opinion, and bear in mind that I am not the wold's foremost authority on identifying coticule layers, that stone sure looks like a Les Latnueses hybrid to me.
The stone second from left on the lower line in the photo is the "Burton Series 0001," A Les Latnueses, and quite possibly the most visually striking of any rock I've ever seen. It was sold, and I don't recall who now owns it, but I would dearly have loved to have bought it, if only to look at!

In any case, the OP's stone bears a strong resemblance ..

Sometimes you can get very strange colours from this layer.

thanks for your input!

the slurry it produced is milky, consistent with my other coticules

I do have a Les Latneuses coticule, mine doesn't have such exuberant colors but it could be posible, 1 thing is that my Les Latneuses has a realy hard hybrid layer and kind of a soft normal coticule layer, I haven't noticed this distinction while lapping this specimen.

The overall hardness resembles the la dressante layer (which I know can look exotic as well but not such a distinct layer transistion)

Martin, I do like your suggestion, looking at the back of my rock it seems to resemble this the most :beer1:

@Piet, I honestly have to say that I don't realy know what type of wood that was, I bought a piece at the fijhouthandel in Arnhem in the section with wood for musical instruments, next time I'll ask ;)

If it's from AF I think it could be palisander/rosewood. Another Dutch member also bought a piece from them and gave me some. I forgot how it looked like :o

hello to all
I also say a coticule I have one who resembles this with orange color
