Where can I find information on Coticule veins?

[badrunner13]

I see a lot of discussion on here in regards to what vein a Coticule is from but I cannot seem to find a direct source that clearly explains the differences. Is there a resource that exists that I haven't found yet? I have three distinctly different stones but I don't know what characteristics that I should be looking for from each of them let alone the name of them. Can anyone point me in the right direction or tell me more about these?


The one on the left came from TSS earlier this year and the other two are vintage glued combination stones. Any information would be helpful.
Thanks again,
Benjamin

Try coticule.be. They have labeled pictures of the different strata. Maybe you match them to what you have.

Okay so looking at coticule.be it looks like from right to left; La Grise, La Petit Blanche, and La Veinette, Does that seem about right?

Here is a LPB and a Veinette. The one on the left is most certainly a La Grise.

The one on the left is most definitely La Grise as Rick said. The one in the middle doesn't look like a LBP to me, it looks more like a Les Lat, although I'm not extremely familiar with them. The one on the right could be a La Veinette, but its hard to say.

Here is my LBP. They tend to be more creamy looking, and are always natural combos with a thick layer of dark blue lines running between the layers
