1.08 Ct. Greenish Blue Sapphire from Madagascar

This fine transparent greenish blue sapphire weighs 1.08 carat, and measures 6.08 by 5.94 by 3.79 millimeters, a classic round shape executed in a mixed brilliant cut that balances fire and color saturation. The mixed brilliant format pairs a well proportioned crown with triangular and kite facets that encourage strong scintillation, with a pavilion that incorporates modified brilliant facets to reinforce return of light into the table. Calculated depth is approximately 63.1 percent, a proportion that places the stone squarely in the zone where light return and face up color intensity are optimized, rather than lost to excessive pavilion depth or a shallow spread. Clarity is graded as very very slightly included at eye level, so the inclusions are minor and do not interrupt the optical performance, and the excellent polish minimizes surface diffusion so that contrast and facet crispness remain excellent across viewing angles. The sapphire is natural with no enhancement, and its Madagascar origin contributes to a distinct color profile that sits between blue and green, with vivid saturation noted as intense in grading.

From a gemological and craft perspective, this stone exemplifies careful cutting decisions made to maximize the unique color and internal light dynamics of Madagascar sapphires. The crown facets are calibrated to produce a play of small, lively flashes that emphasize the stone surface, while the pavilion facet architecture is arranged to return light efficiently, producing a deep, velvety face up tone without undue dark zones. The mixed brilliant approach also helps to mask minor inclusions through reflective interaction, so the very very slightly included clarity does not detract from visual appeal. The intense color intensity communicates strong chromium and iron balance within the corundum matrix, and because there is no heating or other enhancement, the color is inherent and chemically stable, providing a reliable appearance under varied illumination from daylight to warm indoor lighting. Excellent polish and accurate symmetry are essential in maintaining that consistent color and brilliance, and those finishing qualities are evident in even facet junctions and minimal polish lines, ensuring that the gem will continue to perform optically after setting and through routine wear.

When considered as a generational heirloom, the attributes of this sapphire combine aesthetic refinement with material resilience and documented authenticity, essentials for a piece meant to travel through generations. Corundum is second only to diamond in hardness on the Mohs scale, with a rating of nine, making it highly resistant to abrasion and surface wear for daily use, and the lack of enhancements means the stone will not experience unexpected changes from temperature or cleaning over time. The round mixed brilliant shape is inherently classical and versatile, allowing future owners to reimagine settings, move the stone from one mounting to another, or incorporate it into different jewelry types without losing character. Recommended settings for longevity include a secure bezel for active wear, or a well engineered four to six claw prong mounting that balances exposure to light with protection at the girdle, and when married to a robust mounting in platinum or a strong gold alloy, the stone will be well shielded against knocks while retaining maximum light intake. Periodic inspection of the setting and occasional professional cleaning will preserve both the stone and its mount, and the possibility of repolishing by a skilled lapidary exists should the stone ever require minor surface restoration, without altering its original material properties or natural color.

At The Natural Sapphire Company we emphasize provenance, craftsmanship, and stable material properties when positioning a gem for long term inheritance, and this untreated Madagascar sapphire is an exemplar of those priorities. The combination of a truthful treatment history, exceptional polish and symmetry, intense natural color, and durable corundum chemistry establishes a compelling case for this stone to serve as a centerpiece that will retain emotional and monetary value across decades. Whether set as an engagement center, incorporated into a pendant that can be handed down, or kept as a collector stone with documented origin and clarity evaluation, this 1.08 carat greenish blue sapphire is engineered to endure, and to convey both the aesthetic sensibilities and the careful connoisseurship that make a gemstone worthy of family legacy.
