2.45 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This oval shaped blue sapphire presents a precise and measured profile, weighing 2.45 carat and measuring 9.38 by 7.75 by 3.82 millimeters, with transparency that allows for clear examination of its internal and external attributes, a mixed brilliant cut that balances large face up presence with controlled light performance, a clarity grade described as very slightly included when evaluated at eye level, an intense color intensity and an excellent polish that refines every facet junction. The gem is heat treated, a standard and stable enhancement used to optimize color and clarity, and it originates from Ceylon in Sri Lanka, a region noted for producing sapphires with lively cornflower and deep ocean blue tones. The Natural Sapphire Company presents this stone with full disclosure of these technical details, enabling informed decisions based on concrete measurements, cut style and treatment history.

The mixed brilliant cut employed for this oval sapphire is a considered synthesis of facet geometry that enhances the inherent optical properties of corundum, translating gemological parameters into deliberate visual outcomes. The crown is faceted in a modified brilliant arrangement, providing multiple small facets that capture and refract incident light into bright flashes of white light known as brilliance, while the pavilion incorporates a combination of pavilion facets that control the return angles and confine light within the stone for maximum internal reflection. This combination reduces light leakage through the base and minimizes the appearance of windows, which can diminish perceived color and sparkle. In an oval outline, the mixed brilliant cut also concentrates blue saturation toward the table, producing a deep and even face up color that reads as intense without appearing overtly dark, a balance achieved through careful pavilion angles and crown height. The interplay of broad facets and smaller scintillation facets creates a varied pattern of light return, with broad, saturated flashes that emphasize the sapphire s core color, interspersed with lively pinpoint scintillation that articulates movement and life as the stone or the viewer moves.

Facet junction precision and the excellent polish further amplify the effect of the mixed brilliant design by ensuring that light rays encounter smooth, accurately oriented planes without scattering from surface abrasion or polish lines, resulting in crisp, high contrast flashes and sustained internal reflection. The stone s transparency and very slight inclusions are positioned and sized such that they do not interrupt the overall light performance when viewed face up, and the cutter s approach uses facet placement to either conceal or integrate natural features into the visual pattern, preserving brightness and color uniformity. Because the overall depth is governed by the 3.82 millimeter profile in relation to the length and width, the cutter s choices produce an optimal balance between face up size and internal geometry, ensuring a satisfying presence on the finger while maximizing retention of light within the crystal. The result is a sapphire that offers both the saturated blue tone associated with Ceylon material and the lively internal reflection that characterizes skillful cutting, with the mixed brilliant format acting as the engine that translates material quality into perceptible brilliance and scintillation.

Practical considerations include the heat treatment applied to the sapphire, which in this case has been used to enhance color uniformity and clarity in a stable manner consistent with trade practices, and the origin from Ceylon, which contributes to the gem s characteristic hue and overall appeal. The combination of a robust cut, careful polishing and a transparency graded as very slightly included supports setting options that expose the table and crown to light, allowing the mixed brilliant facets to perform optimally in a variety of mounting styles. For clients seeking a stone where measured specifications and controlled optical performance are paramount, this 2.45 carat Ceylon sapphire delivers a clear statement of quality, with the mixed brilliant cut engineered to maximize light return, sustain intense face up color and maintain scintillation across movement. The Natural Sapphire Company provides this gem with detailed provenance and technical description to assist gemological assessment and to ensure the stone s attributes are fully understood prior to setting.
