Friends here have told me that what they enjoy the most are my comments about where I found material, or how I processed it, etc. So I will continue to share that info which is fun for me. Most of my material is found in the field, but I buy some too. This is 1 week in tin ox, another week in tin ox, then 6-9 hours in ivory soap burnish.

This isn't all of them, but all of them except for the Tecovas jaspers which I'm keeping separate so those photos will come at end. One of the fun things I do each year is try to find a large piece of material that most people seldom buy that large, and then try to tumble it. This Kambaba "jasper" took a while, and it's not perfect, buk I'm happy with it. It's just under 2lbs and a bit over 4" long. The shine is satin, not high shine. I put the green ones together for fun. I forget the name of that bright green rock, but think it came from India. There are two pieces of Larsonite and I forget those others.

A wide variety of PW. Those bright colored pieces are my first time tumbling that kind of pretty PW. I bought those pieces at Quartzite just to get some experience. Man were they tough! More chert, mostly stream chert. I really like that dark piece at the back. It's palm-size. More metal and metallic pieces. All are psilomelane or psilomelane-laden except for those 2 duller pieces of hematite. Most of these I found in the California desert, but the hematite was purchased as well as the pure psilomelane. I have some closeups of that one piece which is very pretty. But it's brittle and touchy to tumble. Sawing it is very touchy. Some agates, and some Mary Ellen jasper. Some chalcedony from Cerro Pedernal in NM. I think all on left is mostly quartzite. The piece on right is Vanport chert from OH.

Misc. larger pieces. The 2 with dark green cast are from Lake Superior or the Fraser River in BC, can't remember which. That striped one has a story about it--somewhere unexpected that I found it--but can't remember it right now. On the left, I think it's called Exotica jasper or something similar, and on the right is unknown as can't remember, though I think it came from Mexico. What in the world is this? It's one of the toughest rocks I've ever tumbled. Took a bit over 2 years in rough grind. Was given to me by someone. Misc. medium size. Forgot to include this striped one is the quartzite pic, as that is what I think it is. It came from Lake Superior. Closeup of misc. smalls mostly 1/2" or so.

Colorful chert from far western OK. This was sold to me as Tiger's eye by the Rock Shed. There is no chatoyance and I don't know what it is. I will ask the owner about it. Wonder if it is some form of Tiger iron.

All of these are beautiful, Bob! That Tecovas Jasper, would you have any pictures of it rough? We’ve run across very similar looking rocks here in Texas and I’ve always wondered what they were. Thanks!

Thanks! The first is raw, the 2nd is after 1 week in rough grind. There are those gray pieces of jasper mixed in which are found with it at times and they are very uniform in appearance. A lot of the Tecovas is very rough and takes a lot of trimming to get rid of bad places including sometimes porous whitish regions. In bright sun this material doesn't look like much. It's only later in the process with patience the beauty becomes apparent. I had no idea in the field that there would be any of those translucent areas.

Wow! Fantastic tumbles! So much color and variety in there!! The little vangard chert from Ohio - is that from flint ridge? I think I read somewhere that the flint is black, all other colors are considered chert, but both 'knapp" the same, i believe. Pretty impressive.

Bob that rock looks like oolitic chert.

Bob, regarding that one rock… I found a similar one awhile back here in south central Texas. I cut a small piece and it polished beautifully. Can’t find what I did with that piece though. Eventually I’ll tumble the whole palm sized rock. From my research, the closest thing I found was oolitic chert. It’s a cool rock, thanks for reminding me about it. I’ll dig it up and get started soon.

velodromed, what is that interesting rock you photographed? I don't think I've ever found anything that looks like that. My first guess would have been dino bone, but in some ways doesn't look right for that.
