0.57 Ct. Yellowish Green Sapphire from Madagascar

This transparent 0.57 carat round yellowish green sapphire measures 4.93 x 4.93 x 3.25 millimeters, corresponding to an overall depth of approximately 65.9 percent, a proportion that balances face up spread with optical performance. The stone is fashioned as a mixed brilliant cut, combining a precisely faceted brilliant crown with a carefully considered pavilion geometry, and it shows an excellent polish across facet planes and junctions. Clarity is graded as very very slightly included when evaluated at eye level, indicating only minute needle and crystal inclusions that do not interrupt the window of clean light return, and the gem is unheated with no enhancement, preserving native crystal chemistry and natural color distribution. Origin is Madagascar, a source known for producing a diverse color range in corundum, and the material exhibits the durability characteristic of corundum with a Mohs hardness of nine, and optical behavior consistent with a refractive index in the range typical for sapphire, factors that together ensure sustained brilliance and wearability in daily settings.

The mixed brilliant cut in this specimen has been executed to emphasize both scintillation and color saturation, with crown facets calibrated to create small, crisp flashes and pavilion geometry aligned to maintain internal light return without excessive leakage. The cutter has optimized the crown to pavilion relationship to allow the medium intense yellowish green hue to present evenly across the table, while preserving weight from the original rough. Facet planning appears to have favored angled star and upper girdle facets to enhance dispersion, with lower pavilion facets arranged to reinforce tone without creating deep extinction zones, and polish quality is such that light transmission is maximized through smooth facet intersections. Clarity characteristics are fine and localized, and under loupe magnification inclusions are typical of natural corundum, with no evidence of fracture filling or diffusion, meaning that the visual appearance you see comes directly from the stone as formed in nature. The combination of cut strategy and the gem native properties results in a lively yet controlled brilliance, a measured play of light that complements the yellowish green hue rather than overpowering it.

The heritage of yellowish green sapphires links to long standing traditions of using green and yellow green corundum as talismans for balance, prosperity, and renewal, a practice found across Asian and European gem lore where the color was associated with growth and protective qualities. Madagascar has more recently established itself in the history of modern gem trade by supplying material that often shows novel and complex tone and saturation profiles, material that lapidaries have learned to respect by avoiding aggressive treatments and by applying jewelry grade cutting techniques that honor the stone origin. At The Natural Sapphire Company we emphasize traceability and ethical sourcing for such specimens, and we value unheated stones for their direct connection to traditional uses and for their rarity in the market. For setting recommendations, a round mixed brilliant with these proportions will sit attractively in a low profile bezel for secure daily wear, or in a four or six prong head to maximize light entry and face up presence, and metal choices will influence perceived warmth of the color, for instance warm yellow gold will accentuate the yellow tones, while white metals provide a cooler contrast that highlights green nuances.

This sapphire is appropriate for clients seeking a technically refined gem that combines measured cutting strategy, natural color intensity, and minimal inclusions, all of which support both aesthetic and conservation preferences. Its unenhanced status and Madagascar origin add provenance value for collectors and designers who appreciate material with a documented history, and the physical proportions make it flexible for bespoke design, from elegant solitaires to multi stone compositions where complementary gems are used to tune overall palette and light performance. The Natural Sapphire Company is prepared to provide further technical documentation and to assist in selection of mounting options that preserve the integrity of the stone, and to ensure that the final piece reflects both the technical merit of the sapphire and the cultural resonance that has historically accompanied yellowish green corundum.
