Another rare beauty from the mother nature!  Natural iridescent Chalcopyrite is not uncommon but in the very crystallized forms like this is extremely rare and one-of-a-kind!  This belongs to my father’s long-kept rare mineral collections, he has four pieces in total and this is the second best piece.  Thick, mound shaped layer of iridescent Chalcopyrite crystals grown on a Calcite matrix, their morphology is tetragonal with multiple twinning that forms a rather spherical clusters.  The colors are extremely saturated and electric with a brilliant iridescence.  The wide array of colors change with the direction of the light source, outstanding!  A top quality specimen from the famous Daye Copper Mine, simply amazing!
