Sharp octagon facets give this stone a faceted-gem look even though it's a solid cabochon — the angled edges catch light differently than a rounded cut would. Weighing in at 10 carats, it has enough presence to work as a standalone focal piece.

  • Structured octagon outline, distinct from softer oval or freeform cuts
  • 13x18mm footprint suits pendants and larger ring bezels alike
  • Consistent lab-created color across the full face of the stone
  • Flat back, AAA graded, ready to set
