    According to the definitions I learned through GIA, CZ is a simulant
    and it is not a synthetic -- a simulant being any stone, natural or
    man-made which is used to imitate another stone.  As CZ is used to
    imitate diamond it is a simulant, but so is white zircon or any other
    white natural stone when it is used in lieu of diamond.  A synthetic,
    on the other hand is a man-made version of a particular NATURAL stone
    -- man-made white sapphire, then is both a simulant and a synthetic. 
    CZ would only a synthetic if cubic zirconia occurs in nature, which
    it does not.  Moissanite, is both a synthetic and a simulant, as it
    is reported that, silicon carbide occurs in nature, though rarely and
    not in cuttable form.
