2.11 Ct. Blue Sapphire from Ceylon (Sri Lanka)

At The Natural Sapphire Company we present a transparent 2.11 carat oval blue sapphire, with dimensions 7.77 by 6.38 by 4.57 millimeters. The gem is fashioned in a mixed brilliant cut, combining a brilliant cut crown with a faceted pavilion that emphasizes both scintillation and color depth. Clarity is graded very very slightly included when evaluated at eye level, indicating inclusions are minimal, fine and well positioned so as not to interrupt the optic performance. Color intensity is vivid, with a saturated blue core and excellent polish that produces crisp facet junctions and mirror like facet faces. Enhancement is heat treated, and origin is Ceylon Sri Lanka, provenance that often correlates with lively mid to deep blue tones and an overall balance between saturation and brightness.

Proportionally this oval exhibits a length to width ratio of approximately 1.22, a proportion that preserves oval character while maximizing face up coverage on a standard finger or pendant. Depth percentage is approximately 64.6 percent when measured against the average of length and width, a depth that contributes to robust face up color without creating excessive darkness. The mixed brilliant faceting scheme places a conventional brilliant table and crown facet arrangement over a pavilion that contains modified step and kite facets, a combination that generates both broad flashes of color and an even contrast pattern. The excellent polish enhances facet reflectivity, improving light return across the table and crown facets, while tight girdle geometry and consistent facet alignments minimize light leakage and reduce windowing. The result is an optical balance where sparkle is finely intermingled with saturated color, rather than one quality overwhelming the other.

Clarity and color characteristics interact to create the visual personality of this sapphire, and the very very slightly included grade signifies that any internal features are small, often pinpoint or feather type, and typically perceptible only with magnification or careful angling at eye level. Transparency is high, allowing internal reflections to develop fully within the pavilion and crown. Color saturation is vivid, and the stone exhibits subtle pleochroic tendencies, showing slightly different blue intensities when viewed along different crystal axes, which can add depth and complexity to the face up appearance. Heat treatment has been applied, a stable and widely accepted enhancement that optimizes blue hue and reduces undesirable undertones, while preserving natural crystal structure. Excellent polish and precise facet cutting further ensure that color zoning, if present, is masked by uniform light scattering and consistent facet symmetry, leading to an even and desirable face up color.

The way this sapphire responds to different lighting conditions is a direct consequence of its cut proportions, faceting style, and intrinsic color. In bright daylight, particularly sky light with high color rendering, the stone will present its truest vivid blue, with strong medium to deep saturation across the table and broad crown facets, and with lively but controlled scintillation from the mixed brilliant arrangement. Under warm incandescent lighting, the blue will take on a slightly warmer appearance, often showing richer royal tones and a softer highlight contrast, which enhances perceived depth and gives the gem a more velvety look. Under modern neutral white LED lighting, which many retail settings use, you can expect crisp color definition, sharp facet contrast and pronounced pinpoint scintillation from the crown facets, making small bright flashes that animate the surface without reducing the overall blue saturation. In dim or candlelight environments, the stone will read darker and more intense, the deep color providing a dramatic single tone that can appear almost inky at extreme low light levels, while localized facet flashes will punctuate the visual field as small bright accents. When viewed with focused spot lighting, such as jewelry display illumination, the mixed brilliant pavilion will produce strong light return with broad flashes and a well defined contrast pattern, ideal for showcasing both color and sparkle simultaneously. For mounting considerations, an open prong setting or a low profile basket will allow maximum light ingress to the pavilion and preserve the balance between color saturation and scintillation, and pairing the sapphire with a cool white metal like platinum or white gold will emphasize its vivid blue character.

This sapphire is well suited to a variety of designs where both color intensity and optical performance matter, including solitaire rings, three stone settings, and pendants where light can interact freely with the pavilion. At The Natural Sapphire Company we can advise on setting geometry and metal selection to ensure the gem performs optimally in daily wear, and we can provide additional photographic and mounting simulations to preview the appearance under different lighting scenarios. If you value a stone that combines technical precision in cut and polish with the quintessential Ceylon blue, this 2.11 carat oval offers a compelling combination of structural quality and visual depth, delivering a refined interplay of brilliance and saturated color across the full range of real world lighting conditions.
