At 9 carats, this octagon-shaped piece falls in a comfortable middle ground — substantial enough to notice, but not so heavy it dominates a design. The multi-sided cut gives it more reflective surfaces than a simple oval, so the fire shifts more dramatically as it moves.

  • Octagon cut with multiple flat facets for varied light reflection
  • 13x18mm, medium weight at 9 carats
  • Lab-created for reliable color consistency
  • Flat back, AAA graded
