Silver on Acanthite    Huang Tong Xiang Mine, Lu Jiang, Anhui Province, China.  This outstanding example measures 5.2 x 4 x 2.8 cm overall and is composed of primary acanthite crystals to 1.5 cm each.  On these can be found coils and wires of silver and small shiny secondary acanthite crystals.  Damage-free floater.  Mounted on a custom engraved acrylic base, this represents an outstanding value.  I am currently unable to replace the specimens, at wholesale, for this price.  $550
