1.18 Ct. Bluish Green Sapphire from Nigeria

This 1.18 carat transparent trillion shape bluish green sapphire is an exercise in precise gem cutting and uncompromised natural quality, offered by The Natural Sapphire Company. The stone measures 6.06 by 6.60 by 4.38 millimeters and presents a classic trillion cut executed to deliver optimal light performance. The faceting displays a modified brilliant arrangement with crisply defined crown and pavilion facets, tight facet junctions, and symmetrical terminations, producing strong internal reflections and even scintillation across the triangular plane. The cut proportions preserve depth and table size to maximize color saturation while maintaining excellent light return, and the polish is graded excellent, creating smooth facet surfaces that enhance brilliance and clarity viewing.

Color and clarity characteristics are of primary technical importance in this sapphire. The hue is a distinct bluish green with intense color intensity and uniform distribution, allowing the gemstone to exhibit saturated tone without appearing dark or murky. The clarity is evaluated as very slightly included at eye level, indicating minimal internal features that do not interrupt the clean visual face up presentation or the stone's overall transparency. Critically, this sapphire is untreated, with no enhancement reported, which preserves the natural trace element balance responsible for its hue and contributes to its market rarity and long term value. Origin information further amplifies its appeal, as this sapphire is from Nigeria, a provenance that reflects specific geological conditions that yield unique trace element signatures and color expressions. Nigerian sapphires have become notable among connoisseurs for their distinct bluish green tones and for the comparative rarity of high quality, untreated material from those West African deposits.

For collectors and trade buyers who evaluate stones on technical merits, the combination of precise trill ion faceting, intense untreated color, excellent polish, and a very slightly included clarity grade creates a gemstone that performs exceptionally in both jewelry settings and gemological study. The Natural Sapphire Company can assist with additional technical documentation and independent gemological reporting upon request, supporting provenance verification and the stone appraisal needs of knowledgeable buyers.
