  • Types of Diamond

    Cuts

  • 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.

    facets (57 when there is no

    culet).

  • Oval Cut Diamonds Oval diamonds are a

    modified brilliant-cut (like

    who likes the look of a

    round diamond, but wants

    something more unique.
