Is this a geode?

[Aehill83]

Can anyone tell me what this is? Found on south central Kentucky. Very sparkly on the inside. Is it a geode? It’s not bumpy like I’m used to

Looks like a geode to me. Might be quartz, or any other type of geode. Did you find it on the ground, or chip it out of the rock it formed in?

On the ground

Looks like petrified wood, maybe a tree branch, all the geodes I have seen are crystaline interiors, but not a rock collector so there could be variations....

I can see rings so I'm guessing that its petrified wood. Nice find!

also has what looks like possibly a branch stub at about 8:00

It appears to be solid clear through and not hollow. Is it spherical? If both are true, it is not a geode, although geodes are common in spots of neighboring Indiana. I suspect it’s also granular if you get a close look at it. It may be an ironstone nodule or concretion. If so, the iron cemented together the surrounding sandstone to create the spherical shape. It would be the quartz of the sand grains which is sparkling.
If you can tell me about where you found it I can look it up on the local geologic quadrangle map and see which units in the area might’ve produced it.

Pruning with "Warts-B-Gone" may clear it up

Yup...could easily be a nodule rather than a geode. Hard to tell from the pics. Kind of an odd center color.
