I wasn't sure were to start this thread. I found these 2 pieces about a foot apart in the corner of food plot. I've found smooth pepples that look look like the same material but I'm not sure. White Quartz wont scratch it. It's too small to try to see sunlight through it and I dont have a very bright flashlight.

Thank you very much JoeM. I have tried to search the net for an identification but if if I include the name of a rock or mineral in the search, I get pages of countertops.

Searching for "Limonite after" (no "") will yield many results.

Okay, your Limonite Cubes used to be shiny gold Iron Pyrite cubes/crystals.
The easiest way to think about it is they are weathering and turning to rust, but it's called Iron Oxides and Goethite.  So the Iron Oxides are replacing the Iron Pyrite. When one mineral replaces another mineral but still retains the shape of the former it is called a "Psuedomorph". Doesn't matter if the original is replaced by Iron Oxides, Silica/quartz, or Calcium, all psuedomorphs.
Here's a link to a Google page you can read more about it;

Like I mentioned, you can find real nice specimens of the Limonite after Iron Pyrite crystals if you can dig them from where they were formed and they haven't had a chance to tumble around in the dirt for hundreds of years like the ones you are finding. Those are in typical plowed field surface find condition. I dug these from an undisturbed site in Stanley County, NC. The shape and sharp edges should look a little more like Iron Pyrite to you.
