1.09 Ct. Green Sapphire from Kenya

This marquise shaped green sapphire weighs 1.09 carats and measures 9.76 x 4.85 x 3.01 mm, presenting a refined elongated profile that lends itself to elegant ring and pendant designs. The stone is transparent and has been faceted with a mixed brilliant cut, a cutting style that combines a brilliant facet arrangement on the crown with step or variation facets on the pavilion to maximize light return while preserving weight and maintaining a pleasing outline. Color is described as an intense green with even saturation across the table and along the length of the stone, providing a vivid presence without appearing overly dark. Clarity is graded as slightly included at eye level, meaning that while small natural inclusions are present they do not significantly detract from the gem when set, and these features can also serve as natural fingerprints of origin and authenticity. The polish is excellent, resulting in crisp facet junctions and a smooth surface that enhances brilliance and allows the green hue to read cleanly in varied lighting. The gem has been heat treated, a widely accepted enhancement in the sapphire trade, applied to stabilize and intensify color and to improve overall clarity, and this treatment has been fully disclosed.

The origin of this sapphire, Kenya, contributes meaningfully to its character and to its market value, on both a gemological and a provenance basis. Kenyan sapphires are known for producing a distinctive palette of greens and teals that result from specific trace element balances and the geological conditions in East African deposits, conditions that differ from those of classic sapphire sources in Asia and Oceania. This regional identity imparts a degree of rarity, since Kenyan finds of high quality transparent material in attractive hues are less common than some larger producing localities, and the geological story of formation in metamorphic host rocks gives each gem a traceable link to a particular mining context. Collectors and designers often value such provenance because it provides a narrative and a level of assurance about the stone that goes beyond simple color and clarity grades. When a gemstone can be reliably attributed to a known source, it can command greater interest from buyers who prioritize responsibly sourced materials, geological distinctiveness, and pieces that reflect a specific terroir in the world of colored stones.

At The Natural Sapphire Company we maintain a focus on clear disclosure, accurate description, and careful selection, and this sapphire has been examined and described to reflect its true attributes and enhancements. The combination of a classic marquise shape with a mixed brilliant cut and excellent polish makes this gem particularly adaptable to contemporary and traditional mounting styles, allowing jewelers to set the stone either as a standalone center or as part of a multi stone composition. The slight inclusions, noted at eye level, will typically be concealed or minimized when the gem is set, and they add to the natural character that many connoisseurs appreciate. Heat treatment is stable and widely considered permanent under normal wear conditions, however recommended care includes avoiding prolonged exposure to abrupt thermal shock and strong harsh chemicals, and routine inspection of the mounting to ensure the stone remains secure. For clients requiring documentation for insurance or for provenance records, The Natural Sapphire Company can provide detailed descriptions and support for third party gemological reports, helping to preserve the sapphire not only as an object of aesthetic value but also as a documented asset with verifiable origin and treatment history.
