Love the comments

I think the silver mica appears darker as mentioned from other side
making it look darker occasionally or possibly crumpled but not different colors looks interesting

the only thing other than Italian that came to mind for me was Harrochov Harrtil lattice patterns but they are a different
angle and shape to the Yellow diagonal ones in this. Really feel it might have some good age to it also
just a feeling based on the mossy polished base. I have used a magnifying glass for marks but to much
wear to tell sadlly...
