A deep olive-green Hedenbergite included Quartz cluster from the famous Huanggang Mine of Inner Mongolia.  The exposed area at the bottom part of the cluster exhibits the dual core nature of growth and the ultimate Hedenbergite pseudomorph.  White substance appeared on some prism faces due to Calcite intergrown.
