1.43 Ct. Bi Color / Parti Sapphire from Ceylon (Sri Lanka)

This cushion shape, transparent bi color parti sapphire presents a restrained and precise profile, its weight of 1.43 carat serving as the central indicator of its premium quality. At 1.43 carat the gemstone occupies a scale that balances presence with wearability, providing a tangible sense of value without compromise to everyday practicality. The dimensions of 7.55 x 5.72 x 3.39 mm translate directly to a stone that sits comfortably within a variety of ring or pendant settings, while the carat weight conveys the material substance that collectors and connoisseurs equate with higher tier sapphires. The cutting style is faceted, executed in a mixed brilliant cut approach, which together with exacting proportions yields a controlled distribution of light and a refined sense of depth. Measured and assessed by The Natural Sapphire Company, this sapphire exemplifies the way carat weight, dimensions, and cutting precision coalesce to define a gemstone of premium standing.

The mixed brilliant cut and faceted execution of this sapphire emphasize optical balance, with a faceting design intended to optimize both fire and overall brightness. The cutter has retained a classic cushion outline, while introducing a mixed faceting scheme that blends larger brilliant facets with smaller pavilion and crown facets, creating zones of contrast that enhance scintillation without sacrificing table transparency. The excellent polish is immediately evident on inspection, contributing to clean facet junctions and minimal surface disturbance, factors that directly influence perceived clarity and light return. The proportions embodied in the 7.55 x 5.72 x 3.39 mm profile demonstrate a conscientious approach to stone cutting, conserving weight while maintaining an elegant silhouette, and preserving the 1.43 carat mass which represents a key attribute for valuation and presence.

Clarity and color are presented with clarity, the stone graded as slightly included when evaluated at eye level, a grade that reflects minor natural features which do not materially diminish the sapphire's structural integrity. These inclusions are typical of natural sapphires and in this instance serve as identifiers of origin and natural formation rather than detractors from quality. The color intensity is medium, and the bi color parti characteristic presents a deliberate interplay of blue and a softer secondary hue, producing attractive color zoning and an engaging visual character as the stone is viewed from different angles. The sapphire has undergone heat treated enhancement, a commonly accepted and stable treatment that improves color saturation and clarity while preserving the gem's natural origin and inherent qualities. Origin is Ceylon Sri Lanka, an established source renowned for producing sapphires with lively color and good transparency, a provenance that supports the gemstone's qualitative assessment.

In practical terms the 1.43 carat weight combined with the 7.55 x 5.72 x 3.39 mm dimensions makes this sapphire suitable for a range of classic and contemporary settings, including solitaire, halo, and three stone configurations, where its measured presence will remain proportional to typical ring sizes. The Natural Sapphire Company provides provenance and evaluation information to accompany the gem, supporting informed decisions and ensuring clarity in presentation. The overall impression is of a naturally occurring, skillfully finished sapphire in a size category that is often sought for its balance of visibility and refinement, with the carat weight serving as a reliable metric of the stone's premium quality.
