This freeform cabochon is made from a picture jasper found in the McDermitt, Nevada caldera complex. It was originally named Gary Green Jasper by Gary Macintosh, the founder of the McDermitt Rock Shop in McDermitt Nevada. It is also known as Harlequin Ribbon, Orbicular Larsonite, or Bog Wood. All of our cabochons are cut with a rounded dome, polished flat back, and back cut to accommodate bezel settings. Colors may vary somewhat from what is pictured due to differences in computer monitors.
