    If I were a "pencil-necked geek" I would accept this. However, the
    two clasps do not "hang" on opposite sides of my neck, they simply
    lay in contact with the skin on the back of my neck. Also, these
    clasps are so small (I won't bother to check their exact size, but
    they're attached to a very small 1mm rope chain), that I believe
    gravity's effect on them is negligible when compared to the friction
    of the chain, caused by the weight of the (large opal, if you read
    my previous post) pendant against my skin. 

    So, in a way that you didn't mean to proffer, I do believe gravity
    plays a part; gravity pulls on the pendant and chain, but I still
    believe that an unbalanced pendant and/or (however slightly)
    asymmetric bail is the main contributing factor. Then again, is this
    really such an important topic that we need to waste the extra
    bandwidth?
