1.14 Ct. Yellowish Green Sapphire from Madagascar

This 1.14 carat oval sapphire from Madagascar presents a precise and technically compelling package for a discerning collector. The stone measures 6.77 by 5.36 by 4.24 millimeters, a dimensional profile that produces a strong face up appearance while preserving proportionate depth. The cut is a mixed brilliant, with a brilliant style crown married to a modified pavilion, a combination selected to optimize both scintillation and depth of color. The clarity grade is eye clean as evaluated at normal viewing distance, which means there are no apparent inclusions to the unaided eye, preserving unobstructed light return and maintaining overall durability. The polish is graded excellent, and the piece bears no enhancement, the color and clarity achieved entirely by natural formation. For purchasers who value traceable provenance and unaltered gem material, The Natural Sapphire Company offers this sapphire with the reassurance of verified origin from Madagascar.

From a faceting and light performance standpoint the mixed brilliant execution on an oval outline is deliberate and technically advantageous. The brilliant crown facets disperse light into a lively pattern of pinpoint flashes, producing scintillation that reads lively in small movements. The modified pavilion facets create larger contrast areas, which serve to anchor the visual field and deepen the apparent color when viewed table up. The cutting geometry yields a calculated depth ratio of approximately 70 percent, a deeper profile than many modern ideals, and that increased pavilion depth concentrates color saturation, enhancing the yellowish green tone when set. The girdle is proportioned to allow secure mounting while minimizing excess metal coverage, and the symmetry of the faceting plan is well controlled, producing even light distribution across the oval outline. The excellent polish provides a crisp facet junction and a mirror like surface that amplifies the stone light return.

Color analysis of this sapphire warrants careful attention because the yellowish green hue is complex and responsive to lighting and orientation. The medium color intensity allows the stone to read both vibrant and nuanced, with primary green tones supported by yellow undertones that temper the saturation and add warmth. Sapphires can display pleochroism, and this material exhibits subtle directional shifts in tone between a greener appearance and a more yellow green face up depending on how it is oriented relative to the viewer and the light source. This interplay enhances visual interest and contributes to dynamic color behavior in jewelry. The refractive index of corundum in general is approximately 1.76 to 1.77, and that optical density combined with the gem cut yields crisp internal reflections and controlled dispersion. The measured dispersion of sapphire is modest compared with diamond, yet the mixed brilliant cutting style maximizes the perceptible fire and scintillation within those physical constraints.

Durability and long term performance are important considerations for buyers who intend daily wear. Sapphire is a 9 on the Mohs hardness scale, second only to diamond among commonly used gemstones, which confers excellent resistance to abrasion and retention of polish over time. The absence of enhancement further supports long term stability, as there are no treatments that could alter or fade with exposure to light or heat. The stone can be set in rings, pendants, or earrings with confidence, though practical mounting recommendations follow from its geometry and optical characteristics. A four or six prong setting allows maximum light access to the crown and preserves the lively scintillation, while a low bezel can be used to protect the girdle if the piece is destined for active daily wear. Metal choices will influence perceived color, with yellow gold emphasizing the warmer yellow aspect and white metals lending a cooler, more green forward appearance. The slightly deeper pavilion suggests that table up color saturation will be strong, so open settings that reveal the pavilion and allow backlighting will showcase the natural color shifts most effectively.

This Madagascar sapphire exemplifies the kind of natural, untreated material that continues to appreciate in desirability over time due to its combination of aesthetic complexity and physical resilience. Its eye clean clarity and excellent polish ensure that the technical craft of cutting remains visible for decades, and the mixed brilliant faceting will sustain lively visual performance in ordinary viewing conditions. The Natural Sapphire Company stands behind the measured attributes and origin of this stone, and we can provide custom mounting options that respect the gem cutting axes to optimize color and brilliance. For collectors and clients who appreciate the interplay of gemological metrics and practical wearability, this 1.14 carat yellowish green oval delivers both immediate visual appeal and enduring value, a natural beauty that will continue to captivate for generations with the right setting and care.
