0.62 Ct. Yellowish Green Sapphire from Madagascar

This Madagascar origin sapphire is a transparent 0.62 carat cushion shape stone with dimensions of 5.15 x 4.86 x 3.02 mm, a mixed brilliant cut, and a clarity grade of very very slightly included when evaluated at eye level. The gem exhibits a yellowish green hue with medium intense color intensity and an excellent polish, and it has been heat treated to stabilize and enhance its color uniformity. The cushion outline provides a balanced platform for the mixed brilliant faceting, which merges pavilion brilliance with table and crown facets designed to emphasize both color and light return. At this size the combination of proportions and mixed brilliant faceting delivers a pleasing balance of scintillation and color saturation, while the very very slightly included clarity ensures that the visual appearance remains clean to the unaided eye, offering a stone that is both suitable for delicate settings and durable enough for everyday wear.

The mixed brilliant cut in this sapphire focuses on optical performance by integrating small faceted planes that generate lively scintillation and larger facets that reveal the stone color and internal characteristics. Compared to classic step cuts that emphasize depth of color and clarity, the mixed brilliant cut returns more dispersed highlights and a more dynamic play of light when the stone is viewed under varied lighting conditions. The excellent polish contributes to a high degree of surface reflectivity, minimizing light scatter and allowing the inherent brilliance of corundum to be expressed. The cut proportions and polish quality work together to enhance both contrast and flash, producing crisp facet reflections rather than dull or milky appearances, and preserving the yellowish green tone without washing it out when illuminated by daylight or artificial light.

When placed in context with other gemstones in its category, this yellowish green sapphire displays a characteristic refractive behavior and luster that differ from common alternatives. Natural corundum has a refractive index that typically falls in the range of 1.762 to 1.770 and a relatively modest dispersion, which results in controlled fire and focused brilliance rather than a high degree of spectral color split. Compared to spinel, which has a slightly lower refractive index and a typically softer luster, this sapphire returns light with a slightly stronger contrast and a more metallic luster that emphasizes facet geometry. Compared to green tourmaline, which commonly shows stronger pleochroism and a more glassy luster, the sapphire maintains a denser look and a firmer visual weight due to corundum s higher specific gravity and slightly higher refractive index. Peridot and other green gemstones often present a brighter, more lime like tone and greater dispersion in certain lighting, whereas this sapphire reads as more restrained and sophisticated in its reflective character.

For buyers seeking a gemstone that blends refined brilliance, reliable physical performance, and nuanced color, this cushion yellowish green sapphire from Madagascar represents a considered choice. The heat treatment applied is consistent with standard practices for color enhancement in sapphire and does not diminish the gem s inherent stability or its suitability for fine jewelry. The clarity grade of very very slightly included when evaluated at eye level provides assurance that the stone will present a clean face up appearance in rings or pendants, while the excellent polish and mixed brilliant cutting strategy maximize light return and visual depth.
