Three Stone Green Sapphire Ring 2.94 Ct., Platinum 950

This ring centers a transparent 2.94 carat round green sapphire, measuring 8.36 by 8.30 by 5.53 millimeters, cut to a mixed brilliant design that balances color saturation and light performance. The stone is graded very slightly included at eye level, with intense color saturation and an excellent polish, and has been heat treated to stabilize and enhance its vivid green hue. Origin is Ceylon Sri Lanka, a source known for lively tone and clean crystal habit, which together support the strong transparency observed in this piece. The mixed brilliant approach on this round sapphire combines a classic brilliant style crown, with kite and star facets that disperse light on the surface, and a modified pavilion that directs light back through the table, allowing the gem to present both scintillation and saturated body color. The cut emphasizes precise facet junctions and tight symmetry so that light paths are coherent and the stone reads as lively and glassy rather than diffuse or muddy.

From a gemological perspective the cut geometry has been tuned to the optical properties of corundum, whose refractive index sits at approximately 1.76, and to the specific width and depth proportions of this crystal. The measured depth of 5.53 millimeters relative to an average diameter of approximately 8.33 millimeters yields a depth around 66.4 percent, a proportion that is deliberate for a colored stone where additional pavilion depth enhances color saturation while retaining strong internal reflection. The mixed brilliant pavilion planes are shaped to favor total internal reflection along controlled escape angles so that long wavelength green light is retained within the stone while shorter wavelength dispersion produces lively flashes. The brilliant cut crown, with its kite and star facets and precise table, is polished to an excellent finish to reduce surface scattering and to maximize return of light through the table. Facet alignment and polish quality are critical, because even minute misalignment or poor polish scatters light across multiple directions and reduces apparent brilliance. In this sapphire the facet junctions are crisp allowing high contrast patterning and a bright, lively face up appearance.

Complementing the center gem are white natural round diamonds weighing approximately 0.20 carats total, graded Very Slightly Included in clarity across VS1 and VS2, with a color grade of F. These side diamonds are calibrated to provide bright white contrast and strong scintillation, their brilliant cut facets acting as reflective accents to the green sapphire, framing its color while contributing pinpoint sparkle. The mounting is executed in 14K white gold, with an elevated prong style that secures the sapphire while allowing unobstructed light entry to the pavilion and efficient egress through the crown. The gallery is open to permit light circulation and to avoid trapping light that would otherwise dull the stone. Hand finishing of the metalwork ensures tight bezel shoulders and crisp prongs that hold each gemstone with minimal metal intrusion into the light path. The Natural Sapphire Company oversees sourcing and cutting coordination so that the Ceylon origin, the heat treatment disclosure, and the final setting are aligned to present the maximum performance of the sapphire and accompanying diamonds. This ring will appeal to buyers who prioritize the technical interplay of facet design, optical behavior, and fine finishing, delivering a piece that reads bright and saturated under both natural and artificial lighting conditions.
