This cabochon of Marston Ranch has nice patterns. Marston jasper is a multi-colored jasper/agate mix that occurs on private property in Eastern Oregon. It is, supposedly, an agate/jasper replacement of petrified wood that was included in a bog eons ago. It is known for its bold colors, primarily red, green and gold although many other pastel colors are often included in the formation. One of the most colorful jaspers from the Northwestern US, it takes a splendid polish and produces spectacular finished pieces.
