dont the scratches on the stone bother when honing? or do you flatten it first.

Haha not always, they appeared both in black-blue metallic or purple color....here is a Combinaison Stone AD20 labelled as "LA LUNE" which is the typical "Special Stone"...

So there are no tight rules, easiest is to difference the black-blue metallic material from the purple material...

So it turns out that I actually have three of these things. I didn't know that they were La Lunes at first I was even told that they were Vosgienne but after careful examination under magnification I realize that they're the same material as my label La Lune.

The first thing that I looked over that really should have told me it was a la Lune to begin with were the saw marks. Another fine detail that gave them away we're fossils in bedded in both the large la lune and the labeled one.

I originally thought that the big one was a hard slow stone but after testing it again and comparing it to my labeled la lune i can honestly say I was wrong. All three stone's perform the same and my mistaken judgement was probably do to inexperience with the stone. Also all three stone's perform beautifully with glycerin and water.

The sizes are
5×1×.13
4.81×2.38×1
8×1.5×1

I spent all this time looking for a la Lune just to find out I had a few!

That looks like a purple La Lune which is way less aggressive than a grey one, I have both colors. Purple one I have is 4" x 2" and I use it with a dap of shaving cream and H2O. I find that 30 or so laps will improve just about any edge and make it smooth. The grey one gives a very sharp but somewhat harsh edge with 6 yo 8 laps.

Interesting stone, been doing some reading here on the various types, mine has a unmistakable metallic blue sheen to it, and with some lather few laps produce a stellar edge, going to have to get some oil as I'd read that many "come alive" with oil...one thread had them coming in at 30k, under 20 laps, while some excel with just water and a light slurry.

Turns out there is a La Lune Double Face hone as well, never had heard of it, and this was the only place I'd seen one...that one looked like a "brown Escher".

Well actually there is the issue that many slates do show the red / purple coloration with green blotches, spots or lines....its a geological redox reduction which results in that type of coloration and inclusion.

The slates of this type could be found in US (Vermont Slate), GB Wales (Welsh slates) and FR France, surely also on other locations of the world....the Lunes are really from France....

The lunes show a quite good comparable surface structure, actually they have a structure, where the Vermonts in most cases are more mottled. The Welsh slates are much cleaner and fine grained looking without too much structure in the slate....
