1.13 Ct. Bluish Green Sapphire from Ceylon (Sri Lanka)

This oval shaped bluish green sapphire weighs 1.13 carats, and presents with precise measurements of 6.51 by 4.94 by 4.15 millimeters. The stone has been fashioned in a mixed brilliant cut, a choice that combines a faceted brilliant crown with a faceted pavilion to maximize fire and scintillation while preserving color depth. Clarity is reported as very very slightly included, evaluated at eye level, which for practical viewing means the gem reads as transparent and eye clean to most observers. Color intensity is described as intense, and the polish is excellent. Importantly, this sapphire is natural and has no enhancement, and it originates from Ceylon Sri Lanka, a historic source known for producing lively and sought after sapphires. The Natural Sapphire Company is proud to present this gem as a rare untreated example that balances presence and wearability for a collector or a client seeking a distinctive center stone.

The mixed brilliant cut is the defining factor in the visual performance of this sapphire, and it is where its value and appeal are most evident. By combining a brilliant style crown with a precision faceted pavilion, the cutter has created a dynamic interplay of light return and color saturation. The proportions are slightly deep, which encourages a richer face up color and an intense bluish green appearance when viewed in standard lighting. This depth also contributes to strong scintillation, which is the contrast of light and dark flashes as the gem or the wearer moves. Sapphires have a refractive index in the range of approximately 1.762 to 1.770, and although they are not notable for the same dispersion as diamond, a well executed mixed brilliant cut will amplify the internal reflections and broaden the perceived brilliance. Excellent polish on the facets ensures crisp light performance and crisp facet junctions, which translates to a lively and luxurious presence on the finger or in a bespoke setting.

Clarity and origin are central to the informed buyer who seeks both beauty and integrity. The clarity grade of very very slightly included, evaluated at eye level, indicates minimal internal features that do not distract from the gem when worn, and in many lighting conditions these inclusions are not apparent without magnification. This level of clarity supports a high degree of transparency and allows the intense bluish green color to be displayed without obstruction. The Ceylon Sri Lanka origin further enhances desirability, because Sri Lankan sapphires often show a bright, resonant character that differs from stones originating in other regions. In an untreated state, the gem retains natural zoning and chromophore distribution that can create a subtle depth and a lively color shift depending on viewing angle and light source. Collectors and connoisseurs value such natural expression, because it communicates provenance and geological history, and it removes the question of enhancement which commonly affects market value and long term appreciation.

For the educated buyer this sapphire represents both an aesthetic statement and a sound gemological choice. At 1.13 carats the gem is substantial enough to command attention as a solitary center stone, while its oval silhouette offers flattering optical length for many ring designs. The fact that the sapphire is unenhanced elevates its rarity and premium relative to heat treated or otherwise modified stones, and the Ceylon origin is an important provenance marker that many experienced buyers seek. Practical considerations also favor this gem, since corundum ranks nine on the Mohs hardness scale, making it suitable for daily wear in rings and in most jewelry types, provided standard care is observed. We recommend a certified appraisal and an independent laboratory report for collectors who wish to document the stone for insurance and historical records, and The Natural Sapphire Company can supply additional imagery, mounting options, and guidance on settings that best showcase the mixed brilliant cut and the intense bluish green color. This sapphire will function as a centerpiece, offering both enduring beauty and the confidence that comes from a well documented and responsibly sourced natural gem.
