Any ideas what this stone might be?

I found this digging around in my grandparents backyard when their neighborhood was being constructed in northern Illinois.

Looks like a chalcedony nodule, but too hard to tell from the photo. Can you please provide some more photos, including close-ups?

Definitely looks like chalcedony. Is there more if it there or was it just this one piece? Do you have a piece of quartz handy that you can use for a scratch test?
