    I would like to point out that while using cryptocrystalline quartz
    is more accurate description of gem chrysocolla, it introduces more
    limited understanding of the process than it has to be. Therefore, in
    my opinion, using simply quartz is preferable for the reason that
    native chrysocolla combines with many other minerals forming variety
    of ornamental materials. Agatized chrysocolla is just one of the
    many. 

    This is repetitious, but once again when we say that something was
    agatized, it does not mean that it became an agate.
