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

This 2.33 carat round, transparent bi color sapphire is presented with precise proportions and a controlled facet architecture that will appeal to collectors and connoisseurs, it measures 7.82 x 7.93 x 5.05 mm, yielding a depth proportion of approximately 64 percent, a value that indicates a slightly deeper pavilion that favors rich color saturation and lively internal flash. The gem is cut in a mixed brilliant style, combining a classical brilliant facet arrangement on the crown with a modified stepped pavilion, a hybrid approach that balances scintillation with color return. The mixed brilliant crown preserves strong table reflections and crown dispersion, while the pavilion steps act to layer color and create a pleasing spread of light across the face up, the faceting sequence has been executed to precise junctions and consistent angles, producing excellent symmetry and excellent polish that are immediately perceptible in hand held examination.

Color analysis of this Ceylon sapphire reveals a delicate, natural bi color effect, presenting warm golden yellow tones intermingled with cool pastel blue in a light color intensity, the two hues are distinct yet harmonious, producing subtle zoning and dynamic pleochroism as the stone is rotated. This is consistent with sapphires from Sri Lanka, where trace element chemistry and growth zoning often generate such dual chromatic expressions, the light intensity ensures the gem remains airy and luminous, while the bicolor character adds complexity rarely found in singly colored stones. No heat treatment or other enhancement has been applied, the absence of enhancement preserves the original crystal lattice and natural trace element distribution, qualities that are especially prized by purists and those sourcing ethical, untreated material. The result is a stone that presents clear, natural color separation under directional light, and a soft face up appearance that draws the eye to both hue and internal brilliance.

Clarity and finish are integral to the gemological profile, this sapphire is graded as very slightly included at eye level, an evaluation that indicates minor internal characteristics which do not detract from transparency or luminosity, in most viewing conditions these inclusions are masked by the stone s mixed facet pattern and are not visible without magnification. These subtle internal fingerprints are typical of natural Ceylon stones and serve as internal signatures of origin and growth environment, they also contribute to light scattering in a way that can enhance scintillation when the stone is mounted. Craftsmanship extends beyond the cutting plan to include precise girdle finishing and a well executed culet point that maintains pavilion integrity, the excellent polish amplifies facet contrast and ensures maximum return of white light, while the mixed pavilion geometry modulates return wavelengths to accentuate the bicolor effect without sacrificing overall brilliance.

As a romantic narrative attached to its physical attributes, imagine a sapphire that captured the exact instant when night yields to morning over the western Sri Lankan hills, the blue of lingering twilight blending with the first gold of sunrise, this gem holds that moment within its facets, each rotation echoing a promise renewed, the very slightly included clarity reads like memory, small, honest traces of the journey that do not obscure, but authenticate, the light within. For a client seeking a story to match technical excellence, this untreated Ceylon bi color sapphire from The Natural Sapphire Company offers both, it provides measured proportions, a considered mixed brilliant cut, natural, unenhanced color and the subtle internal character that speaks to origin and authenticity, our team can advise on settings that exploit the depth proportion to emphasize either the warm golden face up or the cooler blue flashes depending on orientation, we take pride in sourcing and presenting stones where craftsmanship and natural history coexist, and we are available to provide additional imagery, viewing options, and bespoke mounting recommendations.
