I took a rock over to Jamie's a couple of weeks ago so she and Rodney could help me identify it. I have had it a few years but was afraid to cut it. Well............Jamie took out the hammer and we busted it in a few places. We were pretty suprised what this rock came out to be. Below is a cab from it that I did today. Still not sure what it is so if anyone has any ideas? lol

I really don't know what it is but it kind of looks like apetite with quartz. How soft is the blue part? Fran

My guess would be Gem silica. It looks like you cut the stone so that the cut was going with the length of the crystals. The middle going length wise in the first pic looks like the form of a long tube. Just my amaturish thoughts on it.
What ever it is, it is really beautiful.

i'm pretty sure its not gem silica. Looks like chrysocola with something i'm not sure.

That looks like an awfully nice piece of chrysocola to be breaking up with a hammer! Nice cab though!

I'd say chrysocolla with limonite inclusions, and some intertwined gem silica. The black spots could be hematite or just chrysocolla (yes, chrysocolla can be black).
The fracturing could be from some moron using explosives instead of hand tools to mine it ... that doesn't look like normal crystal habit.

I have no idea on ID, but that's a gorgeous cab! Such a rich blue/green and I love the clear parts interspersed.

It is a gorgeous color.
I would think if it was Chrysocolla, Jamie & Rodney would have known.

The blue green color makes me feel its chrysocola, the material looks like its from peru or arizona i guess.

Super material. It sure looks like some kind of copper silicate.

Sheri, That is chrysocolla. We only broke off the crumbling rind on the outside of the rock. It looks like Morenci chrysocolla and the fractures are just crazing meaning it is friable. The streaks of silica/chalcedony are what is holding the cab together.
You did a great job on the cab.

Michaeljohn, I think you are thinking of Tenorite. That is a black mineral that is commonly found throughout veins of chrysocolla. By the way, are you still mining chrysocolla from your claim? I'd sure like to see the trench you have been making, bet its pretty big by now. If you have any pictures of your mine, I'd love to see them. Next time we go to some of our favorite locations, I'll try to get some pictures for you.

I really don't mine that much of the Chrysocolla, due to the difficult and dangerous climb. I don't like to do it alone, so now that my Son moved away the trips up there are even less frequent. I plan to go up there by myself soon, though. I'll go up there early one morning, mine all day, spend the night up there, mine all day again, then come back down before dark. While mining, I'll put the good stuff aside, so that the following several trips up there can be quick up-n-downs, without having to mine.
As far as the black specs in the topic cab, yes, if the material is from your "neck of the woods", you're right, it's probably tenorite. That's common for your area.
I'm working on getting my truck in better running condition. Once I'm confident that it'll be more reliable, one of the first little trips I want to make is down to the Phoenix area, to meet all of you folks there and do some hounding. I've hated being this close to all you guys and not getting to hang with you.

Wow Sheri, that stuff looks almost like blue dino bone with that sort of cellular effect going on! Definitely one highly silicified hunk of copper minerals that for sure. Super interesting cab. Thanks for giving us a looksee....Mel

Interesting cab (material). Not sure on what it could be, someone has posted or you find what the mystery stone is.
