This is an old time materials acquired by my father in around 2000.  Striking, iridescent Chalcopyrite crystals almost completely covered the Calcite crystals grown underneath.  They look like a plate of armor worn to protect the Calcite, so interesting!  There is a good isolation between the Calcite crystals and the Chalcopyrite are highly crystalized.  The iridescence is in a metallic color ranges from red, orange to yellow which is in lovely contrast to the white Calcite crystals!  And the Calcite exhibit a medium red fluorescence under UV lighting 365nm.  No more of this style have been found since, they are definitely rare and desirable.  Comes with a high quality copper-wired display stand.
