Morgan Hill Poppy Jasper, found in Santa Clara County, California, is a famous, but increasingly rare orbicular jasper with red and yellow orbs.  It is a brecciated japer, oxidized iron-rich whose cracks were filled in by other substances.  This material is no longer being mined, but occasionally pieces surface from long held collections.
