1.50 Ct.Tw.Total Carat Weight Bluish Green Sapphire Pair from Ceylon (Sri Lanka)

This pair comprises two transparent Ceylon sapphires with weights of 0.84 carats and 0.66 carats respectively, presented in an oval outline that favors classic proportions for high quality mounting. The larger stone measures 6.37 by 4.80 by 2.93 millimeters, and the smaller stone measures 6.15 by 4.60 by 2.77 millimeters, producing length to width ratios of approximately 1.33 to 1 and 1.34 to 1 respectively, proportions that yield a balanced face up presentation without exaggerated elongation. Depth characteristics are optimized for light return, with calculated depths of approximately 52.5 percent for the larger oval and 51.6 percent for the smaller oval, measurements that sit within the preferred range for oval mixed brilliant cutting to achieve strong brilliance and controlled scintillation. The size and proportions are close enough to read as a matched pair when set side by side, and the modest weight difference gives flexibility for use in symmetrical or intentionally offset designs.

Cut and finish are engineered to amplify the bluish green hue and transparent body color, the mixed brilliant cut combining a faceted brilliant crown with a modified pavilion architecture to maximize internal reflection while conserving rough weight. The faceting grid produces frequent small flashes and a lively scintillation pattern when the stones move, while the oval perimeter and excellent polish ensure crisp facet junctions and mechanically stable settings. Clarity is graded as very very slightly included based on eye level evaluation, indicating inclusions are minimal and not distracting to the unaided eye, which preserves apparent transparency and allows strong light transmission. The color reads as bluish green with medium intensity, a tone that shows attractive saturation without being overly dark, and the stones display the subtle pleochroic behavior typical of corundum that allows slightly different blue and green responses depending on orientation under directional light. Enhancement is heat treatment, a stable and widely accepted method used to optimize color and remove silk, and origin is Ceylon Sri Lanka, a provenance known for lively tone and refined crystal habit, details that are documented by The Natural Sapphire Company.

As a matching pair for luxury jewelry collections these stones offer multiple avenues for high end design, their close proportions and consistent color permitting classic matched earrings, a twin center for a bypass ring, or paired accents in a bespoke necklace pendant ensemble. In earring applications the oval mixed brilliant geometry responds well to four or six prong settings that preserve the pavilion angles for maximum light return, and to halo constructions where a fine row of pavé diamonds will increase apparent diameter while maintaining color contrast. For metal selection white gold or platinum will reinforce the cool bluish green signature and preserve perceived saturation, while yellow and rose gold may be used intentionally to warm the overall presentation and create a vintage juxtaposition against the sapphire tone. The slight weight disparity can be accommodated in symmetrical designs by adjusting halo diameter, bezel edge thickness, or metal rail width, or it can be embraced in deliberate asymmetric couture pieces where a gentle size gradation is an articulate design element.

In the context of a curated luxury jewelry collection these Ceylon sapphires serve as technical examples of precision cutting married to thoughtful color management, making them ideal for connoisseurs who value facet architecture and material provenance as much as aesthetic presence. Their medium intensity bluish green fills a niche between saturated teal and classic blue, offering designers a versatile color that pairs well with near colorless diamonds for contrast, or with colored gemstones for tonal layering. The excellent polish and mixed brilliant faceting ensure that mounted examples will photograph cleanly and exhibit dynamic performance in natural and gallery lighting, qualities that collectors and retailers require for principal pieces. The Natural Sapphire Company can provide further gemological documentation and mounting recommendations to translate these measured attributes into finished jewelry that meets exacting standards for luxury collections, and our team can advise on prong counts, halo proportions, and metal combinations to ensure the pair performs optimally once set.
