Item Description

Beautiful lustrous emerald-green euchroite prisms are dramatically strung out in two bands on the thin oxide-coated matrix plate on the rich and excellent small cabinet from the historic Type Locality. Euchroite is a rare secondary copper arsenate and this is a very fine example from this long extinct copper deposit. The crystal isolation is uncommonly fine on this piece. Ex Jack Parnau Collection, prominent California field and mineral collector, who passed away in 1990. He sold most of his collection in 1974. See his biography in the Mineralogical Record Biographical Archive at: http://www.minrec.org/labels.asp?colid=785. Undoubtedly older material!
