Has anyone had experience with this stone?
A friend of mine got a small (about 1" stone) piece and after I looked around to see what it was .... it is a strange stone.
Julie
Thanks again as usual

The color is only on the outer coating. You can tumble it...but it won't look the same in the end!

the "peacock" color is caused by the metal ore on the surface tarnishing... I was thinking....becasue of this, it may be possible to tumble it, and then find a way to re-tarnish it to restore the peacock color, like maybe soaking it in water and epsom salt (or something like that)... Perhaps you could tumble a single piece in your next batch and then experiment...if it doesn't work you are only out one rock...  Mike |

I've heard the peacock colors are from heating the stuff. Similar to the Russian Rainbow Pyrite. Try and tumble a couple pieces then heat in in the oven or with a torch and see what happens. If I could find the box of Peacock ore that someone gave me to see what I could do with I would do with I would experiment myself...

that might work... I'd try the torch first.... I bet you could re-tarnish them after they are tumbled... |

The color is probably from oxidation and you might get the surface color with heating in a stong oxidizer solution like the oxidizer used in spas or OxyClean or even hydrogen peroxide. I dont know if you would need extreme heat or not to fuse tjhe surgace. Interesting exoperiment. I've seen copper jewellry that had been colored with a torch, too. You can get the same effect on titanium, but I'm not sure how it's done.

I don't think out of all the questions I have asked since coming to this board has a rock generated such responses.
Oven, torch, .... re-tarnish ...
Maybe it is a good thing I do not have any of this precious little stone ... ;D
So many rocks, so many puzzles .... what's a girl to do
