Quartz – rock crystal, sphalerite, pyrite, galena

One outstanding, very aesthetic, large cabinet size specimen, presenting, skeletal galena crystals, singenetically developed with perfect black sphalerite – marmatite crystals with very lustrous crystal faces.  and shiny small pyrite crystals. All these crystals are overgrowth by long axes, thin transparent, quartz crystals forming a space net and in the empty spaces are developed small and very shiny pyrite crystals – all that reminds a very aesthetic Christmas tree.
