What part of Oregon. In the field? At a shop? Knowing location and circumstances is helpful.

There is an area, in central Oregon, generally known as Hampton Butte, where green petrified wood, or varying quality, can be found. There are other locales where green jaspers are not uncommon. There are a few areas that are little known where copper ore specimens can also be found. Then there is green serpentine, which is widely scattered across southwest Oregon and parts of the Coast Range.

When you let us know where and the circumstances of finding your rock, those of us familiar with the region can better help you.

Time for lots of coffee.

found in Vale Oregon on top of the ground desert area. It is not transparent at all and the brown part is lava rock
other than being green it has the feel of basalt, but not as soft.

I went to high school in Nyssa and we use to see that kind of rock all over above the high line canal. My Uncle called them green agate.

Green and blue jaspers can be found from Ontario to well south of McDermitt, in Oregon, Idaho, and Nevada. I suspect that is what it is.

Most jaspers from that area are varying shades of brown and red. Greens and blues are uncommon, but not extremely rare. Many types of picture jasper and cutting grade rhyolite can also be found.

Not bad for an eyeball find. Enjoy.

Still time for coffee.

My Uncle called himself a "rock hound" and he really liked the high country between Ontario and Hunington and south west. His main search was for what he called "thunder eggs". That whole country is heavy volcanic area and those type of stones used for jewelry are fairly common.
