2.05 Ct. Bi Color Sapphire from Ceylon (Sri Lanka)

This sapphire is a transparent, bi color oval weighing 2.05 carats, with precise dimensions of 7.33 x 6.83 x 4.89 mm, a mixed brilliant cut, and a clarity grade recorded as very very slightly included when evaluated at eye level. The cutter has maintained excellent polish across all facets, producing sharp facet junctions and a lively surface finish. Color intensity is assessed as medium intense, with visible zoning that presents as distinct but harmonious green and yellow green areas when the stone is rotated under direct light. Origin is Ceylon Sri Lanka, and the stone is natural with no enhancement. The proportional relationship between the average diameter of approximately 7.08 mm and the measured depth of 4.89 mm yields a depth percentage of approximately sixty nine percent, a depth that supports strong internal reflection and sustained color saturation without appearing overly deep in hand. The mixed brilliant design here combines a conventional brilliant crown with a pavilion that balances broad flashes and scintillation, a choice made to optimize both life and color contrast in a bi color sapphire.

From a faceting and craftsmanship perspective this gem demonstrates thoughtful orientation and cut planning. The mixed brilliant cut uses a brilliant facet array on the crown to maximize return of white light and scintillation, while the pavilion facets are cut with slightly elongated angles to concentrate color along the long axis of the oval. The cutter oriented the rough to preserve the bi color band rather than disperse it, resulting in a clear demarcation that reads as two related tones under many lighting conditions. Facet proportions show careful attention to pavilion depth and crown height, yielding consistent light return and controlled windowing despite the stone being moderately deep. Girdle finishing is even, and the polish grade of excellent indicates minimal surface residue or abrasion, factors that are important to experienced buyers seeking both optical performance and longevity in everyday wear. The choice of a mixed brilliant style over a full step or full brilliant approach reflects a deliberate compromise to enhance both brilliance and color play, especially in a bi color material where directional phenomena such as pleochroism must be respected.

Optically the sapphire offers attractive behavior for collectors and designers who appreciate nuanced performance characteristics. Clarity is very very slightly included at eye level, a condition that implies the presence of fine inclusions such as minute crystals or subtle silk trails that do not obstruct the table or the major facet windows, and that contribute little to no impact on transparency. These fine inclusions often act to diffuse light slightly and can enhance the perceived depth of color, a desirable effect in medium intense sapphires. The stone exhibits pleochroic tendencies, revealing greener tones when viewed along one axis and warmer yellow green tones along the perpendicular axis, a feature that adds dynamic complexity when set in jewelry that allows rotation. The refractive index typical for corundum means that light is efficiently reflected and refracted within the material, producing strong brilliance relative to many other gem species. Because the sapphire is untreated, its stability and value are greater than heat treated counterparts, and its natural state will age predictably under normal wear. For setting advice, warm metals such as yellow gold will emphasize the warmer green yellow aspects, while white metals such as platinum or white gold will present the cooler green flashes more starkly. Orienting the long axis of the oval so that the bi color division aligns with the finger or pendant axis will best showcase the stone in motion.

There is a romantic narrative embedded in the gem that complements its technical excellence, a story that can be shared with the wearer and kept as part of the jewel provenance. Born in the hills of Ceylon Sri Lanka, where early morning mists lift from tea terraces and sunlight passes through layered leaves, this sapphire carries the memory of shifting light between green and gold, the same movement that creates its bi color character. Imagine the first meeting of two people on a late afternoon walk, when sunlight begins to slant and the world changes hue, a transition that mirrors the stone transitioning from cooler greens to warmer yellow greens as the viewing angle changes. The very very slightly included clarity becomes part of the narrative, described as the trace of a shared secret or a small remembered moment, an inclusion not as a flaw but as evidence of an authentic life beneath the surface. At The Natural Sapphire Company we present this gem as both a technical precision object and a soulful talisman, ready to be set in a design that allows its bi color personality to speak, ready to become a center for new memories and to age gracefully with the wearer. If you prefer, we can provide further photographic views under different light sources and consult on ideal mounting options to emphasize either tone, and to ensure the stone is showcased to its fullest technical and aesthetic potential.
