Here is a tremendous specimen recently posted by Facebook friend and fellow collector Yasuichi Okazaki in Japan.
The specimen 37mm X 26mm X 46mm is primarily sphalerite crystals but intergrown with bright gold wires.
In his post Yasuichi goes on to describe other minerals, pyrrhotite, jamesonite and ankerite present on the piece, see photos below.
Certainly a beautiful piece and not one I have seen before!
