Hi Kelley,

    I too was confused about the culet until I recently figured it out
    (if I'm wrong, I'm sure someone will correct me). Take for example a
    brilliant cut diamond. It can have 57 or 58 facets. The 58th facet is
    the culet. If a culet (very small facet at the bottom of the diamond)
    is not cut into the stone before the pavilion facets are cut, there
    is a danger of the bottom point being chipped and thus ruining the
    diamond. So, a small facet is cut and then the pavilion facets are
    cut, hopefully so that there will be a lovely point at the bottom and
    NO culet. However, sometimes a culet facet is left. Hopefully it will
    be so small that it cannot be seen through the table of the stone but
    sometimes (in a poorly cut diamond) the culet facet can be seen. 

    I hope that makes sense. So a stone may have a culet with an actual
    diameter (hopefully tiny) or it may have none and come to a point. 

    As for the other measurement you mention, I'm not sure as I've not
    yet purchased that book. 

Regards,
Helen Hill
