Unknown Jasper Cabochon

We aren't sure of the source of this jasper but based on the color it most likely comes from Oregon.  It does have a clear agate area at the top.

The cabochon measures 35 x 20 x 7.1 mm.  It has a girdle height approx. 2.7 mm and is sloped at 5 degrees for ease in setting.  The back is also polished.
