Hearts and arrows ideal-cut rounds carry a widening premium

Round natural diamonds cut to the precise symmetry needed for the hearts-and-arrows optical pattern are commanding a wider premium over standard excellent-cut rounds than in past years.

• The hearts-and-arrows pattern, visible through a specialist viewer, only appears in stones cut to near-perfect symmetry, a smaller share of production than standard excellent-cut grading implies.
• Buyers increasingly ask to see the pattern directly rather than relying on a grading report's cut grade alone, since two excellent-cut stones can differ in how cleanly the pattern shows.
• The premium reflects both the cutting precision required and the additional yield lost achieving that symmetry from the same rough.

We can show the hearts-and-arrows pattern directly on request rather than asking you to take a grade on faith. Contact us to view a stone through a viewer before deciding.
