0.79 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This listing presents a transparent 0.79 carat pear shape blue sapphire, with precise dimensions 6.72 by 4.67 by 3.53 millimeters, cut in a mixed brilliant style and finished to an excellent polish, offered by The Natural Sapphire Company. The stone is classified as slightly included under an eye level clarity assessment, and it displays a medium light color intensity with a clean cool blue hue typical of fine Ceylon material. The sapphire has been heat treated, a stable and established enhancement that improves color saturation and overall eye appeal, and its documented origin is Ceylon, Sri Lanka. These factual parameters provide a concise technical baseline for gemologists and experienced buyers evaluating face up appearance, optical behavior, and suitability for precision mounting.

From a cutting and optical engineering perspective, the mixed brilliant pear combines a brilliant facet arrangement on the crown with a modified brilliant pavilion, optimized to deliver lively scintillation while preserving maximum color face up. The measured pavilion depth of 3.53 millimeters relative to the average of the length and width yields an approximate depth proportion of 62 percent, a proportion that supports balanced light return in corundum when the gemstone is viewed in standard jewelry lighting. The pear outline exhibits a finely tapered point and a well rounded bulbous end, which indicates controlled symmetry through the girdle axis, and the facet junctions visible in the images show tight meeting lines that correspond with an excellent polish grade. The crown facets are cut to create crisp star facets and well proportioned kites, while the pavilion facets are calibrated to minimize windowing and reduce contrast loss, thereby enhancing apparent tone without forcing over saturation. These cutting choices are deliberate, they favor face up luster and blue saturation control over excessive depth, a consideration particularly important in sapphires of this size.

Color and clarity interplay in this sapphire to create a rare combination for the 0.79 carat pear category. The medium light intensity delivers a delicate yet distinct blue that reads as classic Ceylon, with a slight cool bias that often produces a subtle violet overtone under mixed lighting. Ceylon sapphires are prized for this lively, velvety blue that is neither excessively dark nor pale, and finding a pear shaped stone near eight tenths of a carat with such even color distribution and transparency is less common than locating round or oval shapes at similar weights. The eye level clarity grade of slightly included indicates the presence of minor natural features, however these do not compromise the stone structurally, and they are positioned in a way that they are largely masked in typical bezel or prong settings. Heat treatment has been applied to stabilize and enhance the color, a standard practice in the trade that when disclosed, as it is here, allows collectors to focus on cut quality, color tone, and origin. The excellent polish contributes significantly to the perceived saturation and brilliance, as smooth, well finished facets maximize specular reflection and minimize surface diffusion.

For the designer and discerning buyer considering setting options, this sapphire’s dimensions and cut invite a variety of applications, from a refined solitaire ring to a pendant that highlights the pear silhouette. The measured depth and overall proportions favor upward or downward point orientation based on stylistic preference, and protecting the pointed end with a secure prong or tapered bezel is recommended to preserve the cutting integrity. Given the slightly included clarity grade, bezel settings can also reduce visibility of internal features while enhancing perceived size through polished metal contrast. The relatively compact 6.72 by 4.67 millimeter table size yields elegant finger presence without overwhelming a delicate mounting, and the stone photographs provided illustrate its scale on the hand for practical reference. The Natural Sapphire Company can provide additional services such as bespoke mounting, matching consultations for companion stones, and official documentation of origin and treatment upon request, enabling informed acquisition and long term confidence in the gemstone.
