    As a GIA alumni, I take an issue with Wayne characterization. When we
    talking about appraising something, we are assigning value to an
    object. Before value can be assigned, it must be determined what the
    object of appraisal is. GIA training has to do with determination of
    what object is using scientific principals. After the nature and
    quality of object, diamonds in our case, was determined, then
    appraisal using these finding can try to assign value to the object.
    The reason that GIA does not teach appraisal, because the value
    depends on market conditions which are impossible to predict and
    frankly useless. The stone can appraise to one value and be valued 
50%
    more or less in 3 month, while quality shall stay the same. 

    In Gerry's case he should have employed gemologist and not an
    appraiser. In my experience, just because someone calls himself a
    diamond dealer does not imply gemological competence. It only implies
    that person knows how to make money selling diamonds or what he
    thinks are diamonds. The adage " Let the Buyer Beware " still
    applies.
