Here is an absolutely remarkable specimen from the famous Tri-State district (Picher Field), displaying fairly big polysynthetic crystals of sphalerite, decorated with sparkling micro epitaxial chalcopyrite.
The matrix is a silicified limestone coated in micro quartz and you can note some late generation, very gem red 'ruby jack' sphalerite crystals on it!
Ex collection Koch (Belgium).
