Three Stone Bi Color Sapphire Ring 3.86 Ct., 14K Yellow Gold

This ring centers on a transparent 3.86 carat fancy shape bi color sapphire, with calibrated dimensions of 12.49 x 8.51 x 4.55 mm, cut as a mixed brilliant. The mixed brilliant faceting pairs a precise brilliant facet arrangement on the crown with modified step facets on the pavilion, producing controlled light return and a stable scintillation pattern across the larger table plane. The geometry yields an overall depth proportion of approximately 43 percent, which balances face up spread with internal light performance in this elongated fancy outline. Facet junctions are sharply defined, and the pavilion angles have been moderated to preserve the vivid color saturation typical of fine Ceylon sapphires. The stone is set to allow maximum pavilion light passage, the open gallery and elevated seat encouraging interaction between pavilion facets and the incoming light field, enhancing the bi color character while maintaining structural stability in the mounting.

Optical grading records this sapphire as Very Slightly Included at eye level, the inclusion profile remaining discreet and not affecting the gemometeric integrity of the stone. The bi color distribution displays a strong vivid saturation with a central area showing warmer tone contrast against deeper peripheral hues, a characteristic that responds well to viewing under both daylight and warm incandescent spectra. The surface polish is graded excellent, with mirror like facet planes that contribute to crisp facet reflections and minimal on face luster diffusion. The sapphire has been heat treated, a standard and stable enhancement applied to optimize tone and saturation, disclosed transparently in our documentation. The material is attributed to Ceylon Sri Lanka, and the combination of cut proportions, facet architecture, and treatment results in a sapphire that presents as lively and stable in color across typical wear conditions.

Accompanying the center sapphire are matched white trapezoid shaped natural diamonds weighing approximately 0.50 carats in total, graded Very Slightly Included with individual designations of VS1 and VS2, and a color grade of F. The trapezoid shoulders have been selected for symmetry to the central fancy outline, their cut geometry designed to sit flush against the sapphire bezel, maintaining optical continuity and minimizing light leakage at the junctions. These side stones are calibrated and set with precision to preserve the visual axis, their pavilion depths and table relationships chosen to harmonize with the mixed brilliant center. The mounting is executed in 14K yellow gold, the shank fabricated with a controlled taper and an elevated basket to secure the profile, while allowing light ingress to the pavilion facets. All metal surfaces are finished to a high polish to complement the gem finishes, and prong seats are cut to exacting tolerances to reduce stress points on the stones while securing optimal alignment.

The Natural Sapphire Company sources this sapphire through channels that emphasize ethical mining practices and supply chain transparency. The material originates from Ceylon Sri Lanka, where our vetted partners operate with documented commitments to fair labor practices, site rehabilitation, and community reinvestment. Each parcel is subject to provenance verification and chain of custody documentation, and our sourcing partners adhere to independent auditing protocols to ensure responsible environmental and social practices. We disclose enhancement details such as heat treatment openly, and provide laboratory documentation when available, supporting informed buying decisions for technically minded customers. This ring represents not only considered lapidary and metalwork, but also a traceable sourcing narrative, and The Natural Sapphire Company stands behind the piece with full disclosure of origin, treatment, and grading observations. For buyers seeking detailed measurements, facet maps, or additional photographic angles for appraisal or certification, our gemology team is available to provide technical reports and consultation.
