Found on creek bank in Western North Carolina. Lots of rain the last couple weeks. Washed it down. Approximately 25 lbs. I recommend muting audio for video as my sidekick was trying to be amusing. Thanks in advance
a coarse-grained sedimentary rock composed of rounded fragments (> 2 mm) within a matrix of finer grained material. "the sediments vary from coarse conglomerate to fine silt and clay" synonyms: aggregate · agglomerate
It looks like it is probably concrete that has tumbled in a river for quite some time in my opinion or as said above a conglomerate.Which is natures form of concrete also known as a concretion, the pressure of all the weight of soils compress into a solid form.The bottom of very old riverbeds have this and it can be called a false bedrock.
My first thought was 'concrete' as well Dana.
It could also be 'high-strength concrete' (used in bridge and road building) due to it's excessive weight?

"Concrete has been used since ancient times. Regular Roman concrete for example was made from volcanic ash and hydrated lime. Roman concrete was superior to other concrete recipes (for example, those consisting of only sand and lime used by other cultures. Besides volcanic ash for making regular Roman concrete, brick dust can also be used. Besides regular Roman concrete, the Romans also invented hydraulic concrete, which they made from volcanic ash and clay."
Thanks everyone!! Does anyone know if there's any value in one of these. There's some beautiful gems I've never seen. The video nor the picture do it any favors. I'm mesmerized by it.

You can always have it professionally polished.
But it's unlikely to ever have much monetary though, I think it would make for a nice display piece on a book shelf.
Here's an interesting 'yellow rock' I found in a field, I polished it with Conservators Wax and it now sits on a window sill.
I think the iron plow strikes give it character.

I appreciate that and awesome idea. Thanks. I'm hopeful it may. I need to post a few pictures of some of the gems. I'll try and update it shortly. Thanks again
