Just unloaded the 2nd tumbling attempt ever for me. Mixed batch - almost all I collected here in Idaho. Rotary roughed, and rest is vibe. Still not perfect, but the learning curve is starting to flatten a bit, ha ha. The shine came out much nicer this time - even though the lighting was bad for photos and they don't show the true shine. Learning a lot thanks to all of your help! For example I didn't like the first polish results, so I backed up and redid redid the 500 grit. Much better. Used lots more ceramic media (still had some crazing ) Also, learned to use the best possible material, and be ruthless in sorting out duds at each stage. I probably need to wash the polish off a bit more, but I wanted to post. Hope you enjoy these. Thanks. - Mark Complete batch: A few nicer ones: Does anyone know what the brownish one on the left side is? I think it is a jasper, but the outside is a neat pattern. Polished up super shiny! more: Some petrified wood, plus coral. Is the bottom right maybe a stromatolite? Can anyone identify these materials for me? Both from eastern Idaho. Does "turtles on a half shell" ring a bell for this one? My kids used to love the Ninja Turtles

Nice! Yeah there is some shine there!
That brownish-orangy one in the thrid photo looks like it *could* be dendritic opal, or some variety of fern jasper or dendritic jasper.
The one in the lower right of the pet wood one - to me - looks like banded chert. There are lots of different types of silicified stromatolite though, so that could be although it doesn't look like any I've seen.
Looks like you've got some sweet hounding grounds though! Congrats on a great batch.

Nice batch. Great rocks. Discipline in culling the chipped, pitted and fractured rocks between stages always pays off. I have to agree with herchenx, the rock in picture six, lower right hand looks like banded chert or flint to me too.

nice job, your close ups are showing some good shine. I like the petrified woods in this batch the best.

That's a great looking batch Mark! Nice variety of stones you've collected up there. I definitely see the mutant turtle
