Cuprite coated with Malachite

A well-formed cuboctahedral crystal of Cuprite measuring to 3.2 cm dominates this small cabinet specimen, all of which is coated by a thin veneer of bluish-green Malachite intermixed with yellow-brown Limonite.   This impressive specimen is from the Andrássy II mine in the Rudabányai Mountains of Hungary.  The large Cuprite crystal sits to one side of a naturally etched and pitted matrix of bluish-green Malachite coating an undulating plate of massive Cuprite.  Several much smaller Malachite covered crude Cuprite crystals are scattered over the matrix.  A large and most pleasing Cuprite crystal for the Andrássy II mine in Hungary.
