Next to yellow and brown, that dark green is one of the commonest jasper/chert colors as it is another of the colors caused by included iron. That color of jasper/chert occurs about everywhere jasper occurs and most types don't have any specific trade name. Trade names are usually awarded when a variety exhibits some fairly consistent ,uniform color or pattern that typifies the type. For example: the dark green jasper with red spots known as bloodstone or the nicely banded, orby dark green Imperial Jasper out of Mexico...Mel

As Mel advised, this is common material. Therefore it won't have a specific locality name. If the look is not distinctive, then why give it a name? Call it Glennzbloodstone. It's as good a name as any.

It's as good a name as any. I know that some places if its recognized has a name. Like mexican crazy lace or butte obsidian. Up here, green jasper is very hard to find and the color looks a lot different. But green jasper is just as good if a location can't be sourced.

If you see a piece of Mexican crazy lace, then you know exactly what it is. Obsidian Butte obsidian same thing.
Montana agate Condor agate Lavic jasper
All the same. Distinctive materials are are diagnosable based solely on appearance. Therefore the name has meaning.
If a material is generic like a green chert/jasper then it fails to deserve a name.
Abc green chert is the same as def green chert is identical in appearance to lmnop green chert. That said, for this green chert material you have, what good is a name?

do you know what town or area it came from in California? For instance on local material I like to say jasper from the matanuska river or epidote from the matanuska valley or something similar like mountian ranges or glaciers.

Well I guess that might help if I ever go to cali, but a general non specific area is what i'd need for the location.

Glenn
I'm trolling you. It could have come from all over the world.
Mel pointed out that type of material is common and widespread.
By saying so he implied knowing where it came from just by looking is not possible.
I think I said so also. But you are not paying attention.

I know its not alaska. it doesn't look like california or washington jasper.. oregon is a possibility.

Glenn, Since green, yellow and red are colors commonly given to jasper by the inclusion of iron salts and iron is super widespread, jasper/chert in green, yellow or red is the commonest type. It would actually be more of a surprise finding a jasper/chert area where various green types did not occur than the opposite. Green chert, usually misnamed jasper, similar to what you've pictured occurs commonly in all the Franciscan Formation chert beds from southern California to Washington state. Up at our old Hunters Valley ranch, the Hunters Valley Chert member was red and green and outcropped in massive quantities. I had to bust through a massive vein to put in a new water line. It's also super common, though higher in quality, in the Rio Grande gravels here in Texas, though most those are jasper not chert since they come from igneous sources in west Texas. Chert is sedimentary in origin. That being said, though red and yellow are more common, green jasper and chert are very very widespread in the western US.....Mel

I'm not sure why green jasper locally is hard to find... it is easier to find colorful agates (very hard to find) than green jasper!

I've pulled green jaspar/chert from all over the mountain I'm on. Quality varies here in SW Oregon. Very common here. Also find it over the border in CA. If it makes you happy, give it a name. Maybe it will catch on and you'll be famous.

Glenn, I am very curious why you should want or need such a specific locality name. I'm not trying to give you a hard time. I know I like to know myself because I sell rocks and jewelry. Do you? I ask because most people who buy rock jewelry (except for collector connoisseurs) really only want to know a common name. The more you can tell them the better, but generally, if you said something like "a green jasper from the Western US" it would be quite acceptable and make a lot of people perfectly happy. Not all pretty rocks have pretty names or come from fancy locations.

Not all pretty rocks have pretty names or come from fancy locations. I just like to name all my rocks with locations... it shares part of the story.. not specifics per say but a broad range... like the talkeetnah mountians (very large range). That stone was actually for someone else. For all I know it could be from India as well. For many people is not necessarily good enough for me I do occasionally sell Items (right now I have 4 more custom orders I need to finish).
