Hey guys, in the picture you can see the darker area around the sconce. It
is not a shadow, they recently changed the sconce and this is what was under
it, it's not just dirt and I'm not positive that honing and polishing would
definitely make it lighter and match. There are 3 of these on the wall.
Has anyone seen anything like this before? The walls are highly polished,
and the other pieces were up for a few decades at least. This is in
Manhattan if that makes any difference, if this has to do with our clean
air. Please let me know any ideas or suggestions. Thanks.
