What is Diamond Cut?

• The diamond cut is a style or design guide used
  when shaping a diamond for polishing such as the
  brilliant cut. Cut does not refer to shape (pear,
  oval), but the symmetry, proportioning and polish
  of a diamond. The cut of a diamond greatly
  affects a diamond's brilliance this means if it
  is cut poorly, it will be less luminous.
