The cut of a diamond is the first and most important of the 4Cs. It defines the beauty of a diamond because it controls how the diamond handles light.

There are two factors that impact the cut of a diamond:

  1. The shape
  2. The quality of the cut

In other words, there can be vast differences in the quality of the cut between two round diamonds, or two ovals, etc.


Other Points to Consider About Cut:

  • An improperly proportioned diamond will never truly dazzle the eye the way a diamond should.
  • Most cutters are more concerned with saving as much weight from the rough crystal as possible, rather than producing the most beautiful diamond.
  • Consequently most diamonds, perhaps as many as 90% or more of the diamonds on the market, have had their beauty sacrificed for weight retention.
  • Diamonds that are cut too deep or too shallow lose light that spills through the side or bottom.
  • Poorly cut stones will be less brilliant and beautiful – and certainly less valuable – than well cut diamonds.
