Malachite pseudomorph after Azurite    Morenci Mine, Greenlee Co., Arizona. Ex. Dr. Steven Chamberlain collection.  For the Morenci Mine this is a very unusual piece.  The entire specimen is a single azurite crystal measuring 2.4 x 2.4 x 1.7 cm which has been replaced by malachite. The surface has a satin like luster which in combination with the curved crystal faces produces a play of colors ranging from almost black to a very light green when turned.  This unusual characteristic is impossible to show in photos.  A very attractive specimen from an important mining district.  Damage-free.   275$
