  • Weight: 11 Cts | Size: 13x18mm | Shape: Octagon
  • The angled octagon facets create distinct light zones — you'll notice the color shifting in blocks rather than a smooth gradient
  • Best for: structured, modern jewelry designs, geometric pendant settings
  • Setting tip: a straight-edge bezel complements the octagon's clean lines better than a rounded one
  • Lab-created for stable, long-lasting color
