i wonder if these pink spots can be garnet.theyre are thousands of them 1-3 microns.the layer looks to me to be la nouvelle but i need a confirmation and dont know wether to classify it as standard or select grade either.there are 2 manganese swooshes on the bbw side.altogether a very nice stone that gives me great edges for shaving.µ

I've never seen a Coticule like that. I've seen those features on separate samples, but never combined on the same stone . I believe I urgently need to pay Ardennes a visit. Weird and exciting things seems to be going on at the current depth they're quarrying.

The specks are no garnets. The garnets in Coticules can't bee seen with the naked eye.

I have a

on YouTube, in which I am studying one of such specks at high magnification. You can see how I can easily scratch a groove in them with a needle tip. If they were garnets, that wouldn't be possible, as garnets are harder than the steel of my needle tip.

If you're a good observer, you'll notice that there's a smaller particle on the right side of the view, that flares up each time the light reflecting of the needle hit it. I don't know if that's a garnet, but it's definitely more in the right range of size.

Sorry that I can't determine the layer of your Coticule. Maybe I'll know more after visiting Ardennes later this month. In that case, I'll post back.

Kind regards,
Bart.

I'm not the one being asked, but it looks to me like La Grise and La Nouvelle Veine merged together, with the Grise side on the bottom. As far as the speckles, I have no clue.

I still haven't got a clue about the speckles either.
I agree with Jared. It looks a lot like a La Grise, certainly with the particular appearance that gradual, reddish transition between the Coticule and the BBW. At the same time, the blue stratification lines, are more consistent with La Nouvelle Veine.

My visit to the quarry yielded no further information. I did not see similar stones over there. Looks like you have a quite unique specimen over there. :thumbup:

Kind regards,
Bart.

My pet theory is that, given that those two layers are right next to each other, they merged where your stone was in the ground, as apparently that has been happening some in the part of the quarry that is currently being exploited.

It certainly is a very beautiful stone. I hope you enjoy it!
