Another Mystery Coticule

[ppetresen]

Hi Folks,

My first stone, a few years old (to me) now was this coticule. Obviously the layer of the stone doesn't change anything, but I'm of course curious. I've never had any issues getting a nice edge off this and when I use a rubber it produces slurry like nobody's business. Interestingly, it has these pink specs in it and the area they are in appears to be slightly softer, something that is only apparent when I lap the stone.

I've attached three photos: one dry, one wet, one with slurry.

Anyone have any thoughts? I've thought maybe La Veille Rouge de Regne (LVRR) but who knows!
