Howdy, The material exclusive of the dimpled pieces, looks to be flint or chert of pretty nice quality. The dimpled pieces might be some sort of petrified mud or even a coral of some kind. Think the ones I saw labeled as mud though, were from Wyoming....mel

Flint or chert...that's what I was thinking. The white piece has some very small veins of some type of shiny stuff (for lack of a better explanation)

norocks: Flint and chert often have inclusions that can be filled with clear chalcedony, quartz crystals, pyrite or marcasite etc......mel

So, would this stuff be worth picking up?

I'm not sure about the lighter lumpy stuff that Mel calls mud, but the flint and chert pieces are definitly worth the time. It will polish up great although it may take a long time to shape in 60/90 because it is so hard. I have been working a few batches for a couple of months with spectacular results. The colors you have should be awesome when finished. Good luck!

I put some hot water in the WF this evening and cut a couple of these. The blue stuff cuts easier than the white, but it is very fractious.

The flint is different to cut than most rocks. The fracturous properties and the harder density makes the stuff a nightmare to cut, and the only way is to go slow.
