JC7315.  Descloizite, calcite.  Berg Aukas, Grootfontein, Namibia.   6 x 11.5 cm  246g.  $200.00.  Brilliant black crystals on what appears to have been a mold/cast, as it is hollow underneath.   Calcite coats the back of the top crystals.   There are a couple of broken crystals.  One is visible on the lower front center area.  Ex Willy Israel collection.     ON HOLD
JC7315.  Closer view.  The broken crystal is in the lower front, slightly left of center.

JC6706.   Descloizite.  Berg Aukas, Grootfontein, Namibia.  7.5 x 8 x 9 cm tall.  524g. $250.00.   A plumose habit of crystals emanating from a rounded whitish matrix free base.  Looks like it was growing on botryoidal calcite or something white.  Minor damage to the lower right, as can be seen as somewhat reflective flat patches in the photo.   I took six shots of this one from various angles to show how it looks depending on what angle you are looking at it from.  A neat piece, different from what is usually seen. A very good specimen.  ON HOLD

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.
