The Four Cs: Diamond Cut
What is diamond cut? Diamond cut is often used to describe a diamond’s shape, however, the cut on a GIA certificate actually refers to how well the diamond has been cut and polished.
Why Is Diamond Cut Important?
A well-cut diamond reflects light internally and then returns it through the top of the stone, making it look livelier and more brilliant. Diamonds that are cut too deep or too shallow will lose light, making them appear less sparkly and decreasing their value.
The GIA also assesses a diamond’s symmetry and balance, and how well it has been polished. The resulting cut grade ranges from ‘Excellent’ to ‘Poor’.
Pragnell believe cut is the most important C, as it gives the diamond life; therefore, we only use diamonds whose cut is graded ‘Very Good’ or above.
