Appearance & Cutting
Broad step facets create long flashes rather than fine brilliant sparkle, while the natural zoning changes character as the stone moves. Its 8.15 × 3.66 mm face-up profile is especially suited to directional, geometric and custom designs.
Clarity & Setting
Natural inclusions are visible under magnification and from certain angles. Buyers seeking a perfectly uniform blue or fully eye-clean sapphire should review the complete gallery carefully; the color variation and natural characteristics are central to this stone's identity.
