I hand cut this cabochon. Measurements are in the title in mm. A heart shape with a satiny matte finish. One of the amazing things about this stone is that it tends to emulate the local scenery with canyons, cliffs, mesas, and buttes out in Eastern Oregon. I'm not 100% sure if this Oregon picture jasper is technically "Chicken Track," "Succor Creek," "Wild Horse" or some other variety of local picture jasper. There are quite a few varieties and I have trouble keeping track of them all! I know it's not Rocky Butte or Owyhee. Oregon is like the promised land of picture jaspers! CHAIN NOT INCLUDED.
