2.12 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This offering from The Natural Sapphire Company is a C.Dunaigre certified Blue 2.12 carat cushion shape blue sapphire, presented in a faceted mixed brilliant cutting style, with precise dimensions of 7.83 x 6.31 x 4.53 millimeters. The stone shows an overall depth that calculates to approximately 64 percent when measured against the mean of its length and width, a proportion that supports both weight retention and controlled light return. The mixed brilliant configuration utilizes a finely tuned crown with modified brilliant facets to optimize scintillation, paired with a pavilion geometry that balances return and saturation, yielding a strong, lively face up appearance. Clarity is reported as very very slightly included when evaluated at eye level, indicating essentially eye clean presentation with only minute silk or pinpoint features apparent under magnification. Polish is graded excellent, and the sapphire is sold with no enhancement, documenting unheated natural color, with origin traced to Ceylon in Sri Lanka.

Color characterization leans to a primary medium to medium deep blue hue with a subtle secondary violet component that gives the stone a cool, vivid personality, classified by the report as intense in color intensity. In practical viewing, the hue presents as a true blue that shifts gently toward violet in certain lighting angles, a result of modest pleochroism typical of corundum with this chemistry and crystal orientation. Compared to classic Kashmir sapphires, which are noted for a velvety cornflower blue and a diffuse, soft light scattering due to dense silk, this Ceylon example maintains a brighter, more crystalline clarity and a cleaner, more saturated surface color. Against the benchmark of high quality Burmese sapphires, which often exhibit a slightly deeper and purer royal blue, this Ceylon sapphire appears lighter in tone but retains high saturation, producing a more luminous, lively blue rather than a dense, inky blue.

A further comparison underscores the distinctive regional signatures that collectors assess when evaluating hue and tone. Relative to Madagascar sapphires, which can present a wide spectrum from vivid blue to slightly inky tones, this Ceylon stone sits toward the brighter, cleaner end of the range, with more transparency and less tendency to local color zoning. Versus Montana sapphires from the United States, which frequently show steelier or teal influenced blues at lighter saturation, the Ceylon origin sapphire here demonstrates a clearer, purer blue with higher chroma and less green influence. Compared to Australian material, which can trend toward deep, inky blue with greenish overtones, the present sapphire is notably more vibrant and radiant at the surface, a quality accentuated by the mixed brilliant cut that favors return of vivid blue light. The unheated nature of this sapphire preserves its natural chromophore balance, allowing the intrinsic iron and titanium levels that generate the blue to be appreciated without alteration.

From a craftsmanship perspective, the cutter has optimized pavilion depth and crown height to balance color saturation, brightness, and dispersion within the constraints of a cushion outline. The mixed brilliant style produces lively facet contrast across the table and crown, while the cushion proportionality creates broad, even face up color with minimal windowing. The very very slightly included clarity grade supports clean table transparency, and the excellent polish enhances facet crispness and the stone mechanical finish. For setting considerations, the dimensions and cushion geometry lend themselves to a range of mounting styles, including classic halo settings that emphasize the intense color, three stone engagement designs that pair the blue center with sidestones for contrast, or bespoke tension and bezel approaches for modern silhouettes. The Natural Sapphire Company provides full documentation with the C.Dunaigre certificate, and our internal assessments align with the laboratory description, ensuring that the combination of provenance, unheated status, precise cutting, and intense natural color make this sapphire a technically distinguished option for knowledgeable buyers seeking a Ceylon provenance blue sapphire.
