    Hi All, Found this reference to Black Gold on the web. 

    "The color of gold is determined by which chemicals it is found with
    or which metals it is alloyed with. Black gold from Brazil gets its
    color from the chemicals found with it. Alloying with malachite gives
    gold a black or near-black purple color."
