Description

First – this is not from any newer or recent find in Sapo Mine, this is  very old material from an old collection in Vienna, discovered in the  early 80s. It looks different to Sapo, habit is more blocky, crystals  are more thick and color is much darker, nearly black but with dark  olive green color. It seems to have an internal structure. What you see  is not on the surface, no cracks or damages – these are internal  reflections. 

 The crystal is set exposed in the center, it 24mm  across and 14mm thick, faces show thin modifications along the edges and  all of them are highly lustrous. Very aesthetic assemble, no  significant damages to report. Hard to photograph, much better in  person.
