0.84 Ct.Tw.Total Carat Weight Blue Sapphire Pair from Madagascar

This pair of natural blue sapphires presents a balanced combination of color, clarity, and proportion, suitable for refined jewelry applications. The stones weigh 0.38 carats and 0.46 carats respectively, each cut to a round outline with a mixed brilliant facet arrangement. The first stone measures 4.27 x 4.28 x 2.87 mm, the second measures 4.16 x 4.11 x 3.41 mm, reflecting modest variation in diameter and depth that can be utilized in asymmetric or complementary designs. Both stones exhibit transparent body tone, a medium intense blue color intensity, and an excellent polish that enhances surface brightness. Clarity is graded as very slightly included when evaluated at eye level, indicating minor internal features that do not detract from overall visual appeal, and both sapphires have been heat treated, a stable and accepted enhancement that improves color uniformity. Origin is Madagascar, a source known for producing sapphires with a spectrum of blue hues and consistent crystallographic quality. The mixed brilliant cut promotes scintillation and dispersed light return, which pairs well with both open and closed settings depending on design objectives.

These sapphires are inherently adaptable to a wide variety of jewelry formats, and their specifications allow for precise planning of settings and metalwork. The slight difference in weight and depth provides options for matched stud earrings with a subtle size contrast, paired pendant and ring combinations where one stone is used as a focal point and the other as an accent, or contemporary asymmetric designs that intentionally celebrate size variance. The shallow profile of the 2.87 mm depth stone is well suited to low profile bezels or flush settings, minimizing snagging and emphasizing table surface area, while the deeper 3.41 mm stone benefits from prong or open gallery settings that allow light to enter the pavilion and maximize brilliance. The mixed brilliant facet pattern responds favorably to prong, bezel, tension, and halo treatments, offering designers latitude to prioritize sparkle, security, or modern minimalism. Metal recommendations include platinum and 18 karat or 14 karat gold in white, yellow, or rose tones, each metal interacting differently with the medium intense blue to produce warmer or cooler visual results, and designers may consider paired accent stones or metalwork to harmonize the slight asymmetry.

From a practical and procurement perspective, these sapphires combine durable performance and straightforward care with design flexibility. Sapphires register nine on the Mohs scale of hardness, making them highly resistant to everyday wear, and heat treatment is a long established procedure that does not compromise structural integrity when stones are properly set. The dimensions and facet structure should be reviewed with a jeweler during the setting design phase to ensure optimal seat geometry and prong placement, particularly if one seeks to preserve table alignment and symmetry across paired earrings or matched components. The Natural Sapphire Company can provide detailed imagery, measured diagrams, and certification documentation upon request, facilitating accurate CAD and hand sketch workflows, and the stones are available for custom mounting services or as loose gems for independent fabrication. Care recommendations include routine cleaning with warm water, mild detergent, and a soft brush, avoidance of harsh chemicals, and periodic inspection of secure settings. Overall, this matched pair from Madagascar offers technical consistency and aesthetic versatility, making them suitable for classic and contemporary pieces where measured proportions and enduring color are paramount.
