This banded green jasper can be found in several locations, and can sometimes be identified based on the size of the bands and the hue of green. I collected my stash from the side of a cliff near Wikieup, Arizona. It was more of a mining effort than merely collecting though. It required chiseling chunks from a band that was about a foot thick and ran for several hundred yards along the wall. Fortunately, the band is only a couple feet up from the river bottom so there was no precarious climbing to do.
Lizard stone isn't the hardest of jaspers out there, certainly not porcelain grade. But it does polish, and makes nice cabochons, especially if you are looking for that unique shade of sage green.
