0.68 Ct. Greenish Yellow Sapphire from Madagascar

This 0.68 carat oval greenish yellow sapphire from Madagascar is presented by The Natural Sapphire Company as a precision cut gem with measured dimensions of 5.72 by 4.62 by 3.19 millimeters, yielding an overall depth of 61.7 percent. The stone is fashioned in a mixed brilliant cut, combining a brilliant style crown with a carefully calibrated pavilion geometry to reconcile scintillation and color retention. The cutter retained proportions that favor light return while supporting a medium light color intensity, and the result is an eye clean clarity grade at standard viewing distances, and an excellent polish that produces crisp facet junctions and an even, glassy luster. This sapphire has been heat treated to stabilize and enhance its yellow to greenish yellow tone, a common and accepted enhancement for material from Madagascar that optimizes visual appeal without altering the natural origin, and the piece is suitable for precision set work where facet alignment and seat depth are critical.

Optically the sapphire occupies a transitional hue range between pure yellow and greenish yellow, with the medium light intensity providing a balance of body color and transparency. The mixed brilliant faceting contributes to multiple tiers of return, with crown facets designed to break white light into localized flashes, and pavilion planning that supports broad zone flashes, producing a measured interplay of scintillation and overall brilliance. The oval outline concentrates color along the length, while the modest depth concentrates saturation centrally without producing windowing or excessive darkness. The excellent polish enhances both specular reflection and internal light diffusion, permitting the color to appear stable under daylight, and subtly warmer under incandescent lighting. The stone exhibits modest pleochroic tendencies, with a slightly greener component visible at certain facet angles, an effect that skilled setters can exploit to introduce dynamic visual interest in finished jewelry.

When considering integration into a jewelry design the greenish yellow sapphire is versatile, and its optical characteristics respond differently to metal color and surrounding stones. In yellow gold settings the warm undertones of the metal reinforce the yellow aspect, producing a richer, more saturated appearance that flatters warm skin undertones, and this combination enhances perceived color saturation without requiring a larger carat weight. In rose gold the pink cast introduces an amber contrast that softens the green component, creating a warm, vintage aesthetic that complements olive and warm beige complexions. In white metals such as platinum or white gold the cooler environment emphasizes the green component and the stone can read slightly fresher and more lively, an effect that tends to be flattering on cool skin undertones that have blue or pink veins at the wrist. For neutral skin undertones the greenish yellow center stone remains highly adaptable, and designers often pair it with small white diamonds to increase perceived brightness, or with green accent stones to reinforce the green secondary hue, depending on whether they seek contrast or tonal harmony.

From a craftsmanship perspective this sapphire benefits from careful seat design and secure prong or bezel construction to preserve its facet geometry and optical axes. The mixed brilliant cut requires consistent girdle symmetry to avoid tilt or off axis light leakage, and given the excellent polish the cutter has left precise facet planes that respond well to a low profile bezel or a four prong setting that allows light entry through the pavilion. Heat treatment is stable for normal wear, and routine care involves avoiding abrasive contact and high heat exposure that could affect mounted settings, with periodic professional cleaning to maintain the stone surface and maintain luster. As with all pieces curated by The Natural Sapphire Company, provenance from Madagascar and standard gemological grading parameters are documented, and our team can advise on metal pairing, setting geometry, and certified mounting to ensure optimal color presentation and secure fit. For customers seeking a technically sound, visually adaptable greenish yellow sapphire for an engagement ring, pendant, or bespoke project this gem combines precise cutting choices and balanced color properties to perform reliably across design languages and skin tone palettes.
