Three Stone Bluish Green Sapphire Ring 1.71 Ct., 18K White Gold

This ring centers on a transparent 1.71 carat round bluish green sapphire, precisely cut to dimensions of 6.51 by 6.34 by 5.02 millimeters, with a modified brilliant faceting schema engineered to maximize both scintillation and color saturation, and a polish graded as excellent. The modified brilliant cut in this stone is characterized by a slightly adjusted facet arrangement on the crown and pavilion compared with a traditional brilliant, providing optimized light return for corundum while preserving face up color integrity. Clarity has been assessed as very slightly included when viewed at eye level, which indicates minor internal features that do not detract from overall transparency or light performance, and which in practical terms enhances the stone with natural identity without compromising brilliance. The combination of precise diameter symmetry and controlled crown and pavilion relationships produces an appealing balance of sparkle and depth, allowing the intense color saturation to remain the dominant visual attribute without excessive darkening or windowing.

Color is a defining attribute of this sapphire, exhibiting an intense bluish green hue that reads differently depending on viewing angle and lighting, a behavior that is emphasized by the modified brilliant cut. The stone’s origin from Montana contributes materially to its character, as Montana sapphires are known for their unique and often complex blues and greens, and for crystal habits that respond well to skilled cutting. This sapphire has been heat treated to enhance color uniformity and remove residual zoning, a standard and stable enhancement for corundum that is fully disclosed and executed to industry best practices. The treatment has yielded a consistent and intense saturation that elevates the visual impact of the gem, while the underlying natural formation and subtle internal features remain evident to trained observation, affirming its provenance and natural history. The result is a gem that balances natural individuality with optimized color presence, making it well suited for a centerpiece setting.

Complementing the center sapphire are white natural round diamonds with a combined approximate weight of 0.08 carats, each exhibiting clarity grades in the Very Slightly Included range, specifically VS1 and VS2, and a color grade of F. These diamonds have been selected and matched for small scale brilliance and contrast, positioned as shoulder accents to enhance the perceived depth of the central tone without overpowering it. The diamonds are set with precision adjacent to the sapphire prong setting, creating measured intervals that allow visual flow from the center to the band, while their high color and clarity grades ensure a neutral and bright interaction with the bluish green center. The mounting is executed in platinum 950, a metal choice selected for its high density, long term wear resistance, and its neutral white color that refracts and returns light without introducing warm overtones. The platinum construction also allows for secure prong architecture and a robust gallery, enabling a balance between secure retention and maximum exposure of the pavilion for optimal light dynamics.

The narrative of this piece and its value proposition are rooted in the synthesis of geological origin, cutting strategy, gem clarity, and artisanal setting, each element contributing to an enduring object suitable for daily wear and generational transmission. Montana sapphires carry a documented history of American mining and gem cutting traditions, and a sapphire of this weight and intense bluish green character is relatively uncommon, which enhances collector interest and intrinsic value. The decision to employ a modified brilliant cut reflects a conscious design choice to translate the stone’s hue into vivid face up presence, rather than to prioritize extreme brilliance at the expense of color, and that design philosophy is further supported by the use of platinum 950 as a stable, high value metal matrix. At The Natural Sapphire Company we emphasize transparent disclosure of the heat treatment and origin, and we document craftsmanship attributes so buyers understand the provenance and technical merits that drive valuation. In practical and investment terms this ring offers a combination of a well documented Montana sapphire, complementary high quality diamond accents, and a secure and enduring platinum setting, together creating a piece that reads as both a technical achievement in gem cutting and metalwork, and as an emotionally resonant heirloom.
