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.
