Very interesting!Well guys, seems that today is the Day !
In the last years I've spent some of my free time doing research on the La Lune and the Special Stone sources.
The task wasn't easy, info available near to zero and most of my research were failures, but one day, I was reading an ancient book from 1826 and after 280 pages, a light turn on in my head and all was me clear.
There are some more research to do for confirm my discovery, specially on field, and maybe could be soon, a friend of mine is offer his help, but I'm relative sure to be on target and I can claim that both this stones were quarried in Domptail, a small village of the Vosges mountains, near to Luneville in the Lorraine department, in French country.
Now the light is turned on also to you, wear sunglasse !!!

I was talking to a friend (probably the same friend) about this yesterday and he had some neat info on the subject. I'm looking forward to reading your findings.
