Do you mean Morgan Hill Poppy Jasper? You can get it on ebay and at a shop in San Jose. The term poppy jasper refers to a great variety of orbicular jaspers. I have a posting in the member photographs section with some of them. Maybe one of them is the jasper you are talking about. Steve
That's what I meant. Morgan Hill jasper. ;D I've seen some really nice looking material lately. But some of that rough is seriously fractured. Is that typical for this jasper? Or is it possible to get some unfractured, stable rough? I've seen plenty of jasper before and wonder why this material is so fractured in the first place.
Steve: There are many forms of poppy jasper generally found wherever there are Franciscan Formation marine cherts outcropping along the west coast of California, Oregon, and Washington. The rock identification section at this site has lots of pics some of us poppy fanciers have posted which can give you some idea of all the varieties (most the pics are in the older pages) There are also isolated locations in the Sierra Nevada foothills and elsewhere. Unfortunately, many of thee coast range Franciscan rock occurs in seismic fault zones and is, therefore, very fractured. The Morgan Hill deposits, though perhaps possessing the most beautiful patterns and colors, are also among the most fractured. Most all the deposits are also on private land and are pretty hunted out too so the price of this gorgeous material is now going pretty sky high. One E-Bay seller is pretty reasonable around $5 per pound but at the last Snyder Ranch Pow Wow I went to here in California, Morgan Hill was going for $5-12 per pound and Hornitos ( the Sierra variety) was $ 12-16 per pound if you could even find it. I personally mine several types and am a great fancier of the poppy varieties and the locations I prospect are all tiny and require hand tools....Mel
Steve- Poppy Jasper is a tough one to get a hold of Unfractured- That is one of the reasons you don't see a lot of tumbled (well except from mel!) stuff- Most of us cab between the fractures- Last I knew Stoner might have some rough he would be willing to sell- PM him and see
I can't tell if thats some Gneiss Schist, or that Schist is Gneiss. All I know is don't take it for Granite
Boy howdy it's fractured. Yesterday I slabbed up about a 4-5 pound chunk of Morgan Hill Poppy Jasper and ended up with a bunch of 2-3 inch pieces. Cutting around the fractures is the only way to cab it. I imagine it's tricky to tumble because of grit lodging in the fractures.
But it's nice stuff. The colors and patterns remind me of the 60s and 70s. That is from what I can remember about those times... ;-)

Rick, Yep the fracture in poppy jasper is so frustrating. My buddy actually drops his slabs on soft dirt to make sure they crack "before" cabbing and they can be real blade breakers in the saw too as they like to shatter at bad times. The Sierra Material is more solid but the best stuff has long since been hunted out and even this material, though from a non seismic region, has often been fractured by weathering and metamorphic processes. I prefer not to treat rocks I work but sometimes I like to fill the worst cracks in Morgan Hill material with Hotstuff. It fills pretty well and helps stabilize the stones. One thing we have to admit, boy poppy jasper has beautiful and unusual color combinations and patterns....Mel

gemsgalore: I need some advice for tumbling my first opal. It's 2"w x 1-1/2"h, circumference is 4-1/2". I only have ceramic filler but no grinding grit on hand. Can I tumble without the grit?

Fossilman: Ed-exactly!!! He seen the purse,told he was going to take it..I called him a moron and he proved to me,that I was right..I was 15,he was 23...
Aug 27, 2015 11:50:07 GMT -5
mr.mohs: gemsgalore-- I got better idea of what to do with that chunk of opal. Rather than put it in a barrel------- hand polish it with 37,000gr emery paper and save it as a specimen...mostly
