Thank you Deb, I knew that but it takes me a while and a battle to get used to copying them from there to here..... I think I've got it now.

Great progress, I also like the kabamba. You have a pretty wide verity of hardnesses there, are you planning to polish them in the same run? Looking forward to the finish.

Very good looking bunch! I, too, am a kambaba fan. I bought a slab on a trip. The vendor told me it was bird's eye serpentine! Ha!

So far, I have kept the Spectrolite seperate. I have also found the rutilated quartz to be crumbly and much softer as a result than I would have thought for a quartz. I believe I will run the Rutile Quartz and the Labradorite together in the final runs. The Agate, Kambala, Fire and Rose quartz, and Amazonite seem to be closer in hardness and have been working well together. I expect the Kambala is a bit softer than the Agate and Quartz, so I may do that with some other materials. I have a first run going in the 6# barrel or banded amythyst, Ocean Jasper, Lace Agate, and some assorted odds and ends, so I may be combining and grouping the stones in that batch with more similar hardness materials from these first batches as I get them to a more finished state and for polishing. I really feel the plastic pellets are slowing down the process, but have been concerned about not having a cushion on the Labradorite and rutile quartz as these seem more inclined to chip or fracture. I welcome recommendations from all of you with more experience.

I have been attracted to this stone for a while, actually all the orbicular jaspers. I have read the Kambala Jasper is actually a fossilized stromatalite (spelling?), a prehistoric algae. I like all the greens, blues, and the contrasting black or deep forest green eye formations. Birds eye serpentine.......... A believable name, I love the creativity of some people who create names for stones when they don't know what it is...... which for the sake of accuracy makes me ask, is it Kambala or Kambaba? or are both correct?

I have always heard it called Kambaba Jasper or Crocodile Jasper. Norcross-Madagascar Minerals, the miners of "Kambaba Jasper" (Crocodile Rock) (and I believe the foremost experts on that subject) says Kambaba Jasper is a "fossilized Stromatolite Algae."
Nice Job on the tumbling. I like them all!!!

I am so anxiously looking forward to the final results on these stones. I am sure its a "newbee" thing, but it is hard for me not to open the barrels everyday to see how they are doing. I appreciate the advice and instruction here.
webminer, I thank you for the name clarification, and very much for referencing your source on the name for this particular Jasper. Although the word Kambala rolls off the tongue a bit better, I will refer to it from this point forward as Kambaba, or crocodile jasper.
I hope to have some further improved photos to add as I go forward, and a few new materials.

It is always a rush opening the tumbler up. Especially when it is time to get them out of polish.
I do not even care if they are the prettiest stones.

Quick question.... I am preparing to go to the finishing stages (500 or 1000) on a few of these. I have checked the hardness scale for everything. Most of what I have is at 7, with the Jaspers listed at 6.5-7, and the Labradorite and Amazonite at 6.
How close in hardness would be recommended to run together for a polishing stage? Is 6-7 range OK to mix?

Some cool looking stuff you got there! You probably would be ok polishing them together, But me personally I prefer to keep it the same during polish to avoid any fractures or dings on the rock.

My experience is that the feldspars at 6 would do better separately but others may have a different experience.

Well, the first re-run load is out of the polish run, and I am disappointed. Perhaps I just cannot get a high gloss shine with this tumbler. I ran from coarse for weeks, to each phase of progression for 8+ days on all grit progressions. I used at least 1 tblsp of grit per pound, so the 3 pond barrel had 3-4 tblspoons of grit. Ceramic media was used as filler with some plastic pellet. All loads were run twice with borax and ivory soap before going to the next finer grit. I am not sure what I am doing wrong here, but I can get a better shine if I hand buff each stone. Here's how they look...... The whole batch Kambaba Jasper
Agates
Rutilated quartz
These are the ones I hand buffed with a polishing compound
Labradorite
Is there a particular polish that may help? I was using the standard rock shed polish. Or maybe I will need to break down and get a vibe tumbler for the polish phase? ?

They look good! Some materials get a better shine then others and some rocks polish better with different kinds of polish.

I would not be dissapointed with that batch. They look Damb nice. There is a really sweet piece of Lab there. I have to get off my butt and post the pics of my first batch, then you will understand dissapointed:). Nice batch of rocks
