Comes from SW Oregon (private claim).
Really nice job on the cab, and you managed to avoid much undercutting. Any tricks to share?

I agree with estimation of Mohawkite.
You'll know that both this and Bumblebee are toxic. Of course toxicity is dependent on exposure and this can / will have been reduced by taking the appropriate precautions. This post is intended for those that are not aware.
Beautiful cab btw!

R2D: Great information. I got some slabs in a trade one time from a guy in Washington I met at the Dryhead claim. His were marked "Siskiyou Stone" which made me think it was either from NW California or SW Oregon where the mountains of the same name are. Great to have a better location. I've cut a couple of cabs from it and it took no special treatment at all. No undercutting on the diamond wheels and it took a great polish with optical cerium on a leather pad....Mel

Northern part of the Siskiyou Mountains makes sense, and I wrote down somewhere that it was Josephine County (likely contributed to the name?). Like pulsite, the claim was being mined for precious metal, and this was a side-product. I'm sure the rock shops in that area would know more about it, but haven't been down that way for 20 years - really should go back. I recall buying some at the Madras and Prineville Pow Wows years ago and found that some of the metallics occasionally crumbled during sawing - softer stone generally, so glad to hear that's not necessarily an issue when sanding and polishing.

Yeah, the slabs I got were very hard quartz with the metallics. No cracking , crumbling or undercutting at all. Very fun material to work....Mel

Josephine’s Crown (also known as Josephinite or Awaruite) displays a gorgeous mix of Pyrite and Chalcopyrite in a black veined white quartz base. A mix of Pyrite, Chalcopyrite and other sulphides in white and black quartz. It comes from deep in the earth in Josephine County, Oregon in and around gold mines. Because Widmanstaetten patterns have been found in several specimens of josephinite, which are typically produced during slow cooling of a homogeneous metal, it is now believed that Josephinite was derived from the earth’s mantle. Josephinite Widmanstaetten patterns are the first known in terrestrial rock. also see adsabs.harvard.edu/full/1949PA.....57...93M |

What's the going price on slabs of this material? I have some, but forgot the prices... Haven't seen any sell in a while, but the couple of places on the 'net selling have them at $0.20-0.25 per gram. I've seen slabs sell (and have sold) for higher and lower than that at auction. Haven't seen it at shows recently. BTW, "josephinite" (aka, awaruite) is a mineral, and not the same as "Josephine's Crown." Josephine's Crown doesn't contain awaruite/josephinite. Awaruite/josephinite isn't a gem material, though it is, along with oregonite, the official State Mineral for Oregon and priced much higher by weight as a specimen than Josephine's Crown. |
