Solitaire Green Sapphire Ring 1.17 Ct., 18K White Gold

This ring centers a transparent 1.17 carat cushion shape green sapphire that measures 6.49 by 5.98 by 3.15 millimeters, cut to a mixed brilliant design to balance optimal light return with a pleasing pavilion geometry. The mixed brilliant approach places a modified brilliant facet arrangement on the crown, paired with step or partially modified facets on the pavilion, creating lively scintillation across the table while preserving depth and color saturation. With the measured depth of 3.15 millimeters the stone shows a depth to average diameter ratio of approximately 50.5 percent, a balance that minimizes windowing while maintaining strong face up brightness. The facet junctions exhibit an excellent polish, which translates into crisp facet planes and minimal surface abrasions, preserving contrast and maximizing mirror like reflections under varying lighting conditions.

Clarity and color are assessed with the practical standards that experienced collectors and setters expect, the sapphire is graded as eye clean at normal viewing distance, meaning no inclusions are visible to the naked eye, which allows uninterrupted light performance through the mixed brilliant pavilion architecture. The color presents medium saturation, which in this green sapphire yields a lively and versatile face up tone, strong enough to read as distinct green while remaining sufficiently light to showcase internal fire and facet dynamics. The mixed brilliant cut complements this color grade, by using crown facet angles to disperse white light and pavilion shaping to reflect internal color back to the observer, so the stone reads consistently across different backgrounds. Excellent polish enhances the apparent clarity and color, because polished facet surfaces reduce light scattering, permitting a cleaner path for light to enter and exit the stone.

Origin plays a significant technical and market role, this sapphire originates from Tanzania, a region known for producing corundum with complex trace element chemistry that can create unique green hues. Tanzanian deposits often yield stones with balanced incorporation of iron and chromium and sometimes titanium, and that trace element mix influences both hue and response to cutting. For technical buyers the provenance matters because it informs expected crystal habit, inclusion types, and color zoning tendencies, which in turn guide cutting strategy and mounting decisions. At The Natural Sapphire Company we document origin because knowing the source assists our lapidaries in selecting facet templates that best leverage the stone crystallography, for example orienting the table to minimize color zoning in face up orientation and choosing pavilion angles that sit within the crystal cleavage and growth plane constraints to avoid internal stress and enhance durability.

The ring setting is executed in 10K white gold, chosen for a combination of structural resilience and a bright, polished aesthetic that complements the green sapphire without overwhelming its color. The mounting uses a four prong solitaire style, with prong geometry engineered to secure the girdle at four symmetrically spaced points, while minimizing metal obstruction around the crown to maximize light entry. The seat and prong cups are formed to match the cushion outline and the mixed brilliant girdle profile, ensuring the stone sits with correct table alignment and even tension. The shank is a classic rounded profile finished to a high polish, providing comfort for daily wear while maintaining the overall minimalist silhouette that emphasizes the gemstone. Throughout our production, The Natural Sapphire Company applies precision hand finishing to the prong tips, internal seat contours, and polish grades, so the overall piece maintains long term structural integrity and optimal optical presentation.
