Multicoloured sculptural Orbicular Jasper freeform, freckled with orbicular or tube inclusions, having one polished face while left naturally unpolished verso. The name Orbicular Jasper refers to the spherical and orbicular structure of the mineralised inflections, the way the mineral formed in a gaseous pocket or earth vent. This specimen exhibits tendencies to being an Agate. Agates are Chalcedony, as are Jaspers, the inflections on this polished nodule develop in a tube form, sometimes referred to as an eye form in Agate terms.
A most attractive colouration of Ocean Jasper which is a trade name attributed to this form of Jaspers due to the locality, a recent discovery, along the intertidal shores of north-east Madagascar and the type of structure of the mineral growth. Technically named Rhyolite ( an igneous quartz and alkali feldspar). Found in Analalava district in the Mahajanga jungles of Madagascar.
