Noel,

    Red topaz is possible, but improbable. Heat treatment and
    irradiation can bring about the red coloration, otherwise, red topaz
    is improbable 

    In todays market almost any coloration is possible because of the
    diversity of treatment. 

    Any deviation from the known natural colors of gems should be
    treated with suspicion. Regrettably, we are fast approaching an era
    in which appreciation of natural gemstones and their naturally
    occuring attributes is no longer relevant or valued.
