First off--it looks like a Heaton to me.
I appreciate all opinions here.
Most importantly--the rust.
I Like to call these “Coffee Can Marbles”. The discoloration is in fact rust residue. It could be from the bottom of a fish tank(which more than likely would include some other polution or stain) but more than likely this one was stored in a can somewhere that collected a bit of moisture—it was near the bottom of the can.
You can leave it as it is or try to bring it back—both are cool imho.
I use this type of product—always use it wet and a tiny bit at a time. Look for the finest grit that you can find. One of these little cups is all that you need for hundreds of rust-stained marbles.
It is used on my shiny teeth at the Dentist office—why not a marble?

Good luck and Marble—On!!

Clean it w fine steel wool, the rust stains will come off. it may take some elbow grease

CLR ,a wet cotton wash cloth and a tooth brush. Metal on glass doesn’t cut it for me. 🔥

Fine #0000 steel wool is how I remove these rust marks. I think the marble is Alley. Similar to a certain Heaton type but busier IMO.

It's not going to hurt the glass, it's a tool even professional window cleaners use.

I'll try the #0000 next time I need to remove surface crude🔥
