Sec. 23.16  Misuse of the words ``brilliant'' and ``full cut.''

    It is unfair or deceptive to use the unqualified expressions 
``brilliant,'' ``brilliant cut,'' or ``full cut'' to describe, identify, 
or refer to any diamond except a round diamond that has at least thirty-
two (32) facets plus the table above the girdle and at least twenty-four 
(24) facets below.

    Note to Sec. 23.16: Such terms should not be applied to single or 
rose-cut diamonds. They may be applied to emerald-(rectangular) cut, 
pear-shaped, heart-shaped, oval-shaped, and marquise-(pointed oval) cut 
diamonds meeting the above-stated facet requirements when, in immediate 
conjunction with the term used, the form of the diamond is disclosed.
