I found this in the dirt today. All one piece of whatever it is. Mostly greyish translucent with very oriented lines of brown in the corner section that makes it glow orange in the sunlight. The edge looks like it breaks like flint or obsidian. But the larger surfaces are like very smooth bark on a tree branch. Any ideas what it is?

    Super cool! The banding, the conchoidal fracturing and the vitreus (glassy, 10$ word, payable in nice rocks or cash) luster says agate to me.

      Hmm, yes. I was going to call it the see-throughyness and fancy lines.

    probably some kind of agate, but I’m no expert. Minerals tend to live in categories and are themselves often compounds of other minerals, so it could be layers of different minerals that have their own names, the collection of which also has a name.

    I’m going to chance and say carnelian agate.

      Very probable that’s it. TIL agate is just quartz, which there’s a lot of where I found it. I think there’s actually a ton of agate in the area, they just aren’t pretty. Mine doesn’t look like anything online from a quick search but the translucent material with the stripes sounds a whole lot like agate. It only looks orange because of the light that’s reflecting off the brown impurity, its not a translucent orange.

      I’ve found a ton of petrified wood during my life and never seen any that was mineralized like this. Not to say that isn’t possible. It would be really cool if this is a agate that formed in a spot left by a piece of bark or something. The unbroken surface does look like wood or bark.
