This rings up as silver on my vaquero . To me it looks like a rock from a creek but it's in a field I seen somthing similar as a property line marker on another post but it had numbers and a line on it and was much bigger this fits in the palm of my hand.

What? What is that circle of white? Was it broken and glued back together? I would be curious to see whats inside.

Long ago, I was a Geology Minor in college, and a "rockhound." The white in the stone is most probably white quartz -- which is often found in "veins" running through a granite matrix. The egg-shaped granite rock in the photo is a typical river-tumbled rock. For a metal-detector to react to it, it must contain an electrically-conductive metal or mineral. Iron pyrite ("Fool's-Gold") is often found in quartz veins in a granite matrix. So is iron. So is gold (but MUCH more rarely). Good luck on finding out which of those metals (or another one) is inside that river-tumbled rock. (No, that is not meant as a sarcastic comment.)

Hammer wouldn't busy it open. It looks metallic where the hammer hit it
