Solitaire Greenish Blue Sapphire Ring 1.37 Ct., Platinum 950

This ring centers a transparent 1.37 carat round greenish blue sapphire, exact dimensions 6.63 x 6.66 x 4.35 mm, cut in a mixed brilliant to refine both scintillation and color saturation. The mixed brilliant combines a brilliant style crown with a modified pavilion, producing a precise interplay between pinpoint scintillation and larger flashes of light, while optimizing face up diameter relative to weight. Clarity is graded as very slightly included at eye level, the inclusions are minor and positioned so as not to interrupt the gem s overall transparency or light performance. Medium color saturation yields a balanced greenish blue that shifts subtly with orientation, a trait consistent with Montana origin. The polish is excellent, resulting in crisp facet junctions and high contrast between light return and dark areas, and the overall symmetry and facet alignment were executed to exacting standards to maximize optical performance and durability.

The mounting is fully realized in platinum 950, chosen for its density and resistance to wear, providing secure metal support and long term stability for the sapphire. The ring profile is engineered so the head elevates the stone sufficiently to admit light to the pavilion while maintaining robust protection for the girdle, and the shank mass is calibrated to balance comfort with mechanical strength. Hand finishing techniques include meticulous surface burnishing and a high mirror polish that harmonizes with the gemstone s excellent polish, and precision setting work ensures secure seats and minimal light leakage. At The Natural Sapphire Company we source this Montana sapphire through suppliers who practice ethical mining methods, emphasizing transparent chain of custody, responsible environmental management, and fair engagement with local communities, measures that support reclamation and reduced ecological impact. Each stone is evaluated by our in house gemmologists to verify origin, cut quality, and finish before setting, making this piece suitable for buyers who prioritize technical gemological integrity, refined platinum craftsmanship, and verifiable ethical sourcing.
