Don - The stripey look makes me think it's Owyhee Sunset. Beautiful pieces!

Hey Don- So, are you a wacker? (you break em up with a hammer?) or do you use another method? Man...you have it down perfect.

I don't know what kind of picture jasper that is. I do know it is beautiful whatever its name!

Very nice rocks! My favorites are the big one with a reddish area, the lomg one half beige/half brown-red and, of course the shine you manage to put on them. I still suspect you sink them in honey Adrian

Man, several of those picture jaspers look a lot alike. From the shine it's one of the harder more silicified types. Off the top my head I'd say Cripple Creek or Wildhorse but heck some pieces look like Owyhee or Succor Creek. I know, not much help huh? *L* Great shine!....mel

Well, we can't use what kind of shine you got on these stones to determine what kind of pic jasper they are because you could tumble the mud on the bottom of my 18" saw and make it shine. ;D Could it have been a pic jasper mix that you bought? Doesn't really matter, they came out fantastic.

Hey all, thanks for the compliments!
I did some searching tonight, and the only light I could shed on this was a note on a bag saying "Oregon picture jasper". So maybe I never knew what kind to begin with, and as Mel says, several of the picture jaspers look rather similar. Still, I'm kind of surprised that Mel couldn't give me the exact GPS coordinates where this stuff originated.. ;D
181lizard - yep, I'm a wacker. I try to shape things as best I can with a hammer/chisel combo, and I use a Dremel tool to take out nasty pits or other troublesome spots. But mostly I use a long coarse grind stage to shape things up and remove blemishes.
stonesthatrock - I use CPP as my polish. I'm not sure exactly what it is, but I believe it is just aluminum oxide with a fancy acronym that really doesn't stand for anything. Sometime people call it Cheap Person's Polish. ;D
-Don

I have to say my favorite is the one in the fourth pic from the top with the "blow hole" in it - looks like a whale head - the batch is perfect as usual - amazing shine on them - I've never managed to get more than a dull shine with picture jasper

What a shine! Those are beautiful. I can't belive you get those shapes by whacking with a hammer and chisel. All I get when I try that is thin chips that are useless for anything. Thanks for the pics.

That's a wonderful batch Don, thanks so much for sharing it. I wondered what PJ would look like hammered and tumbled - my ususal approach, and you've given me somthing to aspire to If I can get half that shine, I'll be a happy puppy. I wondered if the picture element would be a waste of time with tumble sized pieces of random stuff, I was wrong - your rocks are stunning, every one would make me smile so I'm investing soon, I'll check back in in about 4 months lol Thanks for the pictures - that should help see me through the weekend!!!! Cheers, H

Thanks again for the compliments everyone.
Okay, I found an old picture I took of the rough, and it's labelled as Wildhorse picture jasper. Kudos to Mel for picking that one as one of his off-the-top-of-his-head choices! I'm going to add that picture of the rough at the top of this thread for people wondering what the rough looked like.
Tony, if you are hammer-cracking rough with a chisel, make sure you give the chisel a good, hard hit... hit it like you mean it! ;D If you hit the chisel just hard enough to break the rock, it often tends to spall off in those little shards you mention. A good, solid whack, harder than you think you need, will get around that problem. This is particularly obvious with something like obsidian -- light hits just produce lots of thin, sharp shards; hard hits break it right where you want. -Don

I heard of a trick called cobbing, have you tried this to help break rocks where you want them? It's simply placing the stone on a hard steel edge (a bit of angle steel would do) and hammering. The blows seem to go straight through the rock and breaks into nice chunks. I recently heard of this trick and have only tried it a couple of times, but it does seem to help quite a lot.
Thanks for the rough shots - it's amazing to see the difference right next to each other like that. Tumbling sure is magic!
Cheers,
Harry.
