Kite and triangle shaped facets radiate from the centre, breaking light into many small flashes of brilliance and fire. Modified means the pattern is adapted to this outline, with extra or reshaped facets to bring out the colour.

  • Pattern adapted to the outline

Sphalerite has more dispersion than diamond, so even small stones throw strong flashes of spectral colour. It is soft, which is why cut pairs of this quality are rarely seen outside collections.

Two 9 mm rounds, one deep orange and one bright yellow, chosen as a deliberate mismatched pair. Loupe clean, 8.45 carats for the pair, 9.15 × 9.10 × 6.67 mm as measured.
