There are some real beautiful pieces in there. Great job. What is on the bottom of those dark brown triangular pieces at the top of the picture that is third up from the bottom? Furthermore, what are those particular stones? Banded chert? They look like walnut. Cool brown color.

now that is a lot of tumbled stone!
Do you burnish after your polish? That can help with polish leftovers.
Also, if there is any porosity to the rock the polish embeds itself (this could also be cause for less shine overall as the pores allow the grits to cross-contaminate)
Like you said, there are some real beauties in here.

Nice, wow, that's about the most inclusive mixed batch I'ver ever seen!
If you are concerned that some rocks didn't turn out as well as hoped, hold off on a polish run until you have enough of a similar-hardness material to fill a barrel... the hardest materials (agates) will always polish well in a mixed barrel, but your softer materials like obsidian, amazonite, wonderstone, rhodonite and Llanite won't reach their full potential because they get beat up by the agates.
BTW, that is Llanite I see, right?, in the fifth picture from the bottom, lower-right side? I tumbled Llanite years ago and got OK results, but someday I want to get back to those stones and see if I can't make them really gleam...

you got some good keepers for sure and the best part about tumbling is that any you are not real happy with can always go for another ride later to try to improve them. Did you use a good amount of ceramic? I find that when I have that many slabettes in mine I need a lot of ceramic to keep all those flat surfaces from sticking to each other and not getting the best polish.

Hey all!!! Sorry so late .... I have always had a polish pit issue with the vibe. But this is a learned skill and patience is key. I burnish with Borax and do my best. With this batch, I mixed a TOO wide range mohs, so bad Julie. Randy ... no those are not Wonderstones.... I believe that is Mookite and it came out smokin hot. I was very surprised and very pleased on how well they came out. Since this batch was started last year when I got the slabs and since did all the cutting and trimming, the batch was long time in the making and I am at a loss as to what is what for the most part. There are some smaller almost perfect pieces of Pet Palm and I love them!!!!!!!! I love anything petrified as well as the obsidian. Another big mistake I made were the Moonstone pieces. Now mind you they came out somewhat okay, but I just do not have the knack for Moonstone. That is Jo's area. I try hard, but it just does not seem to work for me. I think for the most part, the ones I have polish issues with should have been in 120 longer before even going into burnish then pre polish. I learn with every batch. As Always! ps ... now all I have to do is re learn wrapping
