Dear William,  

    From what I know, I have to disagree with the above statement you
    made. I do not think that fluorescence alone will allow you to
    distinguish either synthetic diamonds or synthetic amethyst from
    their natural counterparts. I have heard and seen demonstrated that
    synthetic diamonds are slightly magnetic and with a powerful enough
    rare earth magnet along with proper low friction placement (on a
    cork on water or suspended from a string) this magnetic attraction
    can be demonstrated. 

    (Anyone care to comment on the above? I am not sure if it proven
    that all synthetic diamonds are magnetic.) 

    As for amethyst, I have already stated my case in past posts on the
    need to visually recognize natural growth clues within the stone.

    PS  Very soon we will have pre-fitted specialty 'pin-caps' to fit
    our briolettes in 14 & 18 K yellow or white gold. These will
    increase setting strengths, decrease manufacturing time and
    dramatically lower your costs.
