    "hardest to polish" is a very optimistic. Next to impossible, would
    be the term I use. 

    The degree of table polish is a critical observation in this case. In
    any even, given unusual orientation, I would speculate that it was a
    CVD diamond. Owner should submit stone to GIA, and if it is a CVD,
    the jeweler may be responsible, depends on degree of disclosure he
    provided.
