History

Grading

Did you know….?  Because the Princess Cut has never been patented, Grading Laboratories don’t grade Princess diamonds a there are no universally accepted standard.

So, we’ve developed our own criteria to provide consistent cut grading for all our Princess Cut diamonds.  These take into account factors such as table and depth percentage, polish and symmetry and length to width ratio.
