I think there some beautiful stones @aliklat218.
What process did you follow? After the rotary tumble , which gave them such nice shapes, how were they finished... rotary or vibe? The first 3 stones looks like Rhodenite... I have found them to be VERY hard to put a shine on those.
That last stone (pic before the whole batch photo) is stunning! ... also the one 2-up from that one... Brown with black boarders (pet??) soooo interesting. Sorry... I do not know their names.

Nice collection. Wonder if differences in hardness cause some to shine better than others.

Glenn Thank you Glen! That is Rhondenite. I didn't know that at the time I got it. Just thought it was a cool pink and black rock. First 3 are the same, just different sides of it. The brown with black is pet, I think. That came from either @tovi0 or manofglass. The last one is crazy lace

What orrum said, shine is over rated. Great tumbles. Soft rocks about always have less luster. Higher hardness is just easier to polish. Harder to shape, easier to polish. It's a rule. wood ?

I've got some rocks out in the vibe being polished with Cerium Oxide as I type. Gonna be some real shiny ones, you betcha!
Just reached up and stuck my hand in a box where I couldn't see, felt around to see what was in there. Found out it was some coral chunks from you. Dang coral has been in there for some time, but it can still get into your skin and sting! Gonna get a blade, see if I can scrape it out. Thanks, James.

It has been my experience that harder rocks polish better. (Discussion is tumble polishing) Like all those Rios, the Montana agate like agates that have waxy faces at the chipped face always seem to polish well and fast. Coral, Brazilian, Montana, Chalcedony healed clear agates all polish fast and well. Move down to softer jaspers and many will take a lesser polish. the agates that were slow to grind on the king Kong grinder always polished well; I used it to test agate hardness. If slow to grind they were simply hard/tough and polishd well. Cast glass verses blown glass, the cast is much harder to polish. The cast nips easily with the nippers, it's softer when nipping too. Mahogany obsidian takes the best polish of obsidians. Move down to felspar and good luck getting a polish on it, I did better with fluorite. Green clear fluorite polishes better than purple. Certain that rocks from different locations act different. Those were mine and behave consistently like green fluorite polishing well. Are you saying the coral cuts ? It hurts like real coral and must have similar chemicals because the cuts often fester. don't think it breaks as sharp as obsidian though. Never tried cerium oxide, is that your routine polish ?

Never tried cerium oxide, is that your routine polish ? Yes, Cerium Oxide is my go to polish, so far I have been using it with everything. When I started tumbling again several years ago, I had an assortment of different polishes picked up over the years. I did some research online, and found that CO was the preferred polish about forty years ago. So I gave it a try, and I really like the shine it gives. I still have a bit left, but I understand it is pricey. Unless I happen across some at an estate sale or something, I may have to switch to something else at some point.

MsAli great batch! Love the variation and colors. This one is my favorite, what is it? The little dot on the bottom right reminds me of the craters on the moon with the radiating lines coming out.

rockpickerforever How much Cerium Oxide do you use? Rotary? or Vibe? I have some that I have acquired over the years and wanted to go ahead and test it out. Thanks Henry

I still have a bit left, but I understand it is pricey. Unless I happen across some at an estate sale or something, I may have to switch to something else at some point. When I started out tumbling rocks I was buying -Grit Kits- , did not pay attention to the material that the polish was made from but it was a white powder. Then I found Kingsley North and purchased a Large Grit Kit from them, it came with 5 pounds each of 80-220-600 grits but only had 1 pound of Cerium Oxide polish. I asked about it here on the forum and was told to use much less CO polish than the other grits. So from that time about a year ago, in a 6 pound barrel I've been using about 3/4 cup of the larger grits and 1/4 cup of Cerium Oxide with great results. Normally I get 2 pounds CO at a time from Kingsley North . . . www.kingsleynorth.com/skshop/product.php?id=46509&catID=189Just noticed that they sell Super Cerium Oxide too, that's the pricey stuff ... www.kingsleynorth.com/skshop/product.php?id=91525&catID=189

rockpickerforever How much Cerium Oxide do you use? Rotary? or Vibe? I have some that I have acquired over the years and wanted to go ahead and test it out. Thanks Henry I do my coarse grind in rotary, fine and polish in a Gy-Roc A vibe, which has a ten lb capacity. Instructions say to use 2 - 3 rounded teaspoons of polish. I used three in this batch, but probably could have only used 2. I should have looked in my log book to see what I used last time, but just went by the instructions. Well, as they say, the proof is in the pudding! I will be pulling them tomorrow night, at the latest. Pics on Monday.....

Wow! Wonder what makes it so much more expensive? From Kingsley North website: "Sometimes refered to as "French Cerium", very high grade of polish." Maybe because it's French? I don't have any rocks that are special enough to require that, lol.
