(bump) If anyone is on the fence on this one better grab now it because I'm going to start knocking down the price by a few bucks every day. A reverse auction of sorts  |

Can this be tumble polished? I've not gotten good results with other rhyolite.

I would probably not sell it as a tumble material. It does however make REALLY pretty cabochons or belt buckle stones taking advantage of the big wide patterns. It typically polishes to a medium satin to high satin shine. This is a cabochon I made from a stone I got at the same time as this batch.   |

[ebr] Just thought I would throw in my (inflation adjusted) 67 cents worth since I've played around with this same stuff. The wonderstone from the Fallon area varies in hardness. You can typically see the variation without even doing hardness testing. Some of it looks more "porous" - this stuff is softer, probably around a 5 like Tommy said. There is also a lot that is harder - it has a smoother appearance when broken. The pieces I've tumbled vary in shiny-ness within the same batch, some took a high shine, others more satin. I've attributed to this to batches with significant variation in hardness. I've got some running right now that I sorted according to perceived hardness, we'll see how that goes. All this said, it's really gorgeous rock. The patterns can be stunning in a tumbled stone. Argh |

Heat treat and the colors get more vibrant plus it gets a lot better shine. I tumble it and cab it and even knapp some. Cook it to 700 plus degRees and raise temp slowly and lower slowly. It's a volcanic ryolite so it's essentially already heat treated so results vary.

It's a good deal no matter which way you slice it. Roughly 80 cents per pound before shipping. But yeah, I loved that chunk too - surprised at myself for not cutting it. |
