If you learned something it is not a failure.

Agree with morlock, feldspar and quartz.

I think morlock’s got this one nailed down. No reason for me to guess.

Hardness of 7.5, round and pock marked, fractures exposing crystal lined pockets? Odds are you’ve got a piece of chalcedony on your hands. And while it’s not unheard of for it to be blue, it is rare and quite sought after by jewelry makers. As to what makes it blue, well I’m not certain. I know there are different mineral inclusions causing the color, but couldn’t tell you which you’ve got. In fact, the only included mineral I can remember that does show up is dumortierite. The only reason I remember this one is because I know someone who has a secret spot where he collects it. He claims this material doesn’t fade with exposure to the sun, unlike blue chalcedony with other inclusions.

Looks like a bit of chalcedony on some other type of stone. Can’t really tell for sure, but that’s the impression I get.

My uncle always suggested walnut shells or corn cob. I’ve always been a fan of plastic beads. When I tumbled l the time I kept two pounds of beads for each grit stage.

Doesn’t look like any horn coral I’ve ever seen. Not sure what you’ve got there.

At first glance I thought it was a chunk of bog iron, but looking close I don’t think it is. I think morlock nailed it.

I’ve looked and looked trying to find out what type of animal left this behind, but have had no luck. I’d wager though that it was probably in a tide pool at some point.

It was on a chunk of sandstone that was full of piddock shells, and also had some tube worm remains. No idea where it came from. It was in the yard of the house we moved into when I was a tiny child.

I don’t know what this is, exactly, but I know that it’s from some sort of sea creature. I’ve found stones coated in the same stuff.

Looks like olivine basalt to me, but virtually impossible to tell from photos.

Oh, you KNOW them? Well that changes everything! okay, let me turn off the sarcasm and get serious for a minute. I just have one simple question. Are they collecting these from public lands, or private property?

I’ve got one dresser right now that looks like this. I’m at work right now but I’ll take a picture or two when I get home.
