Enargite in such sized crystals is uncommon, and this is a sparkling display piece made showy by the presence of sparkly pyrite atop! Large and stout prismatic Enargite crystals cluster that is completely dusted with tiny, glistening Pyrite crystals really give this an unusual aesthetic, and it stands out dramatically. An old specimen purchased by Ed Ruggiero when it came out in the mid-1970's, it is quite different than the typical "clean" black crystals with matte luster we have seen from Peru since that time. It is a balanced, pretty specimen that displays enargite at a size any previous collector of USA minerals would kill for (when compared to Butte Montana material, typically the old standard). Overall an unusual metallic combo piece.
