1.27 Ct. Yellowish Green Sapphire from Tanzania

This transparent 1.27 carat cushion shape yellowish green sapphire measures 6.54 by 5.40 by 4.46 millimeters, and its proportions reflect deliberate material optimization by our lapidaries at The Natural Sapphire Company. The mixed brilliant cut combines a brilliant facet arrangement on the pavilion with a carefully modified crown pattern, producing both strong return of light and controlled face up color. Facet junctions display crisp alignment and an excellent polish, enhancing scintillation and preserving sharp windowless light performance. Color intensity is described as intense, with a balanced yellowish green hue that presents lively green body color with secondary yellow flashes when viewed off axis. Clarity is graded very very slightly included, evaluated at eye level, and the inclusions are minor, well positioned, and do not detract from the gem s transparency or its dispersion of light. The sapphire is unenhanced, no enhancement, which means the natural color and crystal chemistry from its Tanzanian origin are intact, offering collectors and connoisseurs an authentic and traceable example of African corundum.

Over years of wear this sapphire will continue to captivate because of inherent material resilience and thoughtful cutting. Corundum s hardness of nine on the Mohs scale confers excellent resistance to abrasion, while the stone s dense refractive index and precise facet geometry maintain lively brilliance and crisp contrast patterns even after routine use. Because this example is unheated, its color stability is anchored in natural trace element distribution, reducing the risk of long term color alteration under normal environmental exposure. The robust polish and well executed girdle proportions reduce susceptibility to chipping, and when set with common protective approaches such as a bezel or a secure four prong with reinforced corners, the gem will sustain its optical performance and structural integrity. For technical buyers who assess cut symmetry, light leakage, and facet terminations, this cushion sapphire delivers on all counts, and The Natural Sapphire Company stands behind the gem with provenance details and setting recommendations to ensure the stone remains a focal point for decades, continuing to reveal its nuanced yellowish green character in different lights and settings.
