    Here's another link to muddy the waters further:
    http://www.mindat.org/min-9845.html 

    Turquoise's chemical composition is CuAl6(PO4)4(OH)8 5H20. A URL
    from another post: 

    http://www.vcnevada.com/Y&TLtd/page7.html 

    states that their white "turquoise" contains no iron or copper.
    Well, gemologically speaking, if it doesn't contain copper, it isn't
    turquoise. I'd really like to see the "assay" report mentioned on
    the vcnevada.com website. I don't know what this white "turquoise"
    really is, but I'll see if I can pick some up to test next time I
    run across it.
