Got around to photographing some of my recent finds today..and since I'm new to the hobby I need help with identification. So I will be making a few threads hoping for your wisdom in ID's. Thx much in advance. This one is from north central WI, it looks like it has a wax coating covering it...
Possibly another agate, try shining it up with some emery paper. Looks a little sand blasted but the dull hue, waxyness, is a good indication for chalcedony.
