1.15 Ct. Green Sapphire from Madagascar

This 1.15 carat heart shape green sapphire from Madagascar, offered by The Natural Sapphire Company, is a study in exacting proportions and optical precision. The gem measures 6.05 x 6.90 x 4.32 mm, producing an average depth of approximately 66.7 percent which sits within an ideal range for balanced light return in a heart motif. The cutter employed a mixed brilliant cut approach, combining the light performance of a brilliant crown with a carefully calculated pavilion geometry, to optimize both scintillation and depth of color. The heart outline displays crisp lobes and a well defined cleft, and the symmetry across the lobes and wings is controlled to maintain a centered table and even light distribution when set. The excellent polish elevates every facet junction, allowing clean facet reflections and precise facet breaks that contribute to an immediate face up brilliance that belies the gem size.

Color is the defining attribute of this stone, graded as intense in color intensity with a transparent body that allows saturated green tones to read strongly at room light. The pavilion and lower main facets are positioned to concentrate color in the core of the stone, while the crown facets are cut to reveal lively flashes of lighter green toward the table. In practical terms this means the gemstone retains a deep forest green in diffused lighting, and produces flashes of brighter green in directional light, creating dynamic contrast and visual depth. Because the sapphire is not enhanced, the color is entirely natural, which is highly desirable for collectors and designers who require authentic provenance and stability of hue over time. The Madagascar origin contributes to the particular green signatures observed in this example, which often combine subtle bluish undertones with a strong green saturation.

Clarity and transparency have been managed meticulously in the cutting process. The stone carries a clarity grade of very very slightly included as evaluated at eye level, which indicates that inclusions are minimal and do not interfere with face up transparency or light performance. These minute internal characteristics are contained to areas that do not disrupt the primary light paths, allowing excellent brilliance and minimal visible distraction to the unaided eye. The mixed brilliant cut further masks any minor inclusions by increasing internal reflection and contrast, which is particularly effective in a heart shape where the distribution of facets around the cleft and shoulders can hide or de-emphasize localized inclusions. The excellent polish ensures that the surface is free of abrasion lines and tourne border irregularities, facilitating secure setting and maximum contact with metal when placed into a custom mount.

From a jewelry design perspective this green heart sapphire is exceptionally versatile and will stand out in any setting. In a solitaire ring, the saturated green and precise heart proportions create an immediate focal point, and a four or six prong mounting with low profile prongs will maximize light exchange and color visibility. A halo of micro set diamonds will increase perceived size and contrast the green, particularly when set in platinum or white gold, while a warm yellow gold setting will emphasize the stones green warmth and deepen its forest tones. For pendants and delicate rings a bezel with a thin polished rim can provide security without deadening the color, if the bezel is executed with a high polished interior collar to reflect light back into the pavilion. The stones hardness ensures robust daily wear, and with no heat or chemical enhancement reported, the color will remain stable. The Natural Sapphire Company can provide mounting recommendations and CAD visualizations to ensure that the final piece showcases the sapphires intense green and exceptional cut quality to best effect.
