Remember, 3/4 full, similar hardness, and filler. Don't rush.

Tiger's eye can be weird too for no explanation. I have never tried tumbling a barrel of only it. Have done a lot of it this year. Some pieces develop problems that repeat no matter how many times I go back to 220. For that reason, it's kind of a tricky rock for beginners to learn on.

BobI wonder if I've just been super lucky; I can get mine nicely polished without a lot of effort, BUT I've never done a load of solely tigers eye either. Hmmm. Guess it's time to buy some more tiger's eye and experiment. For science*! *Totally not for science.

Mel, it seems to me some tiger's eye may have edge fibers that are not as tight as others. I'm just speculating. I recently tumbled red and blue for first time. With gold maybe 75-90% do fine. With red, my experience so far 50%. With blue, out of maybe 15 pieces, none have edge fibers that met my expectations. Went bad in 600 or 1,000 or polish. Going to avoid blue for awhile. Love the red though, yet no pieces completely done yet.

50%?!?!? Booooooo. Good to know though because my latest batch of rough is red tiger's eye. It's so beautiful, I hope it doesn't get all roughed up. You're probably totally correct about the fibres; maybe stephan could chime in? I know that I find there to be a lot of variance between specific rocks (same type) from the same area. Not too shocking. Mother Nature doesn't have much in the way of a quality control department.

I will confirm what another poster said earlier: the white stuff are bruises which happen a lot with tigers eye, which trends to be a relatively delicate material. Try re-tumbling with more small stones / filler to create a more gentle tumble. Tigers eye is a tougher material to tumble for this reason.

Not too shocking. Mother Nature doesn't have much in the way of a quality control department. I don't tumble, so I can't help in that regard. General knowledge of tiger's eye, though: red is heat-treated gold tiger's eye. The latest I've heard is that all the asbestos has been replaced by silica, so it should be less "stringy" than the blue, which still contains asbestos. When cabbing, I've not noticed any under-cutting, but is is certainly likely that the crystals are less well-packed than jasper or agate, so some cushioning media might help (I've heard people here talk about plastic pellets, walnut shells and kaolin clay). Good luck. Hopefully the tumblers can help with that. If I think of anything else, I'll let you know.
