RockandFound Posted May 23 Share Posted May 23 My guess is petrified wood especially since it was found with a bunch of quartz and the banding but I’ve never seen any pictures of petrified wood like this. Hardness is 6-7, the deep brown is Gemmy. Maybe its a limb cast. I found it in Moulton TX where their is also a lot of oil in the ground. Idk if that has anything to do with it but I’m very curious about what caused the blue color in the one. If you know anything about it I’d be very interested in what you have to say.

4meter Posted May 25 Share Posted May 25 Its a Quartz nodule (concretion). I'm sure there are a dozen possible Rock Hound, and Gemologist terms for it as well. There are lots of these in the limestone rocks of East Tennessee. Quote Link to comment Share on other sites More sharing options...

Interesting. What about the blue color? Maybe copper oxides? Btw I’m from TN but didn’t get into rockhounding till I moved out west. I’m traveling up there in a week recommend any good spots in middle TN. Quote Link to comment Share on other sites More sharing options...
d_day Posted May 28 Share Posted May 28 These look like flint nodules. Like 4meter says, they form in holes in limestone. Quote Link to comment Share on other sites More sharing options...

It can be quite difficult to ID something from pictures alone. Quote Link to comment Share on other sites More sharing options...
