JC9047.  Diopside, melanite.  Serpentine Dome, San Benito county, California.  11 x 19 cm  >1000g.  $50.00.   30 or so years ago, these were typical of the diopside rich zones of melanite in this area.  This old timer generates from that time period, and may date back to the 1960's.   White/cream bladed diopside heavily coats the matrix, with myriads of tiny, sparkly melanite crystals interspersed throughout.   Rare to see these anymore.
