Three Stone Greenish Blue Sapphire Ring 1.15 Ct., 18K White Gold

This ring centers on a 1.15 carat cushion shape sapphire from Montana, with precise dimensions of 6.09 x 5.62 x 4.06 mm, cut as a mixed brilliant to marry the depth and color saturation of a cushion outline with the scintillation of a brilliant facet architecture. The mixed brilliant execution retains a slightly rounded square girdle silhouette while employing a brilliant style crown to maximize light return and lively sparkle, and a carefully proportioned pavilion to preserve color depth and minimize light leakage. The stone exhibits intense color saturation in a greenish blue hue, offering an even, velvety tone across the table without pronounced color zoning. Clarity is graded as very slightly included, evaluated at eye level, which indicates small internal features that do not compromise transparency or face up performance, and the sapphire has been heat treated to stabilize and intensify its color, a standard practice that results in an even, durable hue. The polish is excellent, showing crisp facet junctions and a smooth, reflective finish that enhances both brilliance and color richness, while the origin of Montana contributes a distinct, terroir driven character that reads as cool, mineral, and authentic.

Flanking the center sapphire are two pear shaped white lab grown diamonds, each weighing approximately 0.20 carats, producing a combined diamond weight of approximately 0.40 carats. Each pear is precision faceted in a modified brilliant arrangement to deliver strong scintillation and a clean, pointed silhouette that echoes the cushion curve of the center stone. The diamonds are graded Very Slightly Included, within the VS1, VS2 range, and carry a color grade of F, enabling high contrast against the greenish blue center while maintaining a neutral, crisp white appearance. The pear shapes are oriented and set to optimize light interflow between the stones, with their crowns and pavilions calibrated to complement the center sapphire’s depth and refractive behavior. The result is a three stone composition where the lab grown diamonds act as calibrated light enhancers, increasing perceived brightness and sharpening the sapphire’s apparent saturation without overtly competing for visual dominance.

The setting is executed entirely in 14K white gold, chosen for its balance of durability and warm white hue when polished, providing a stable framework for everyday wear while reflecting light into the stones. The shank is slender and ergonomically contoured, tapering subtly toward the shoulders to concentrate visual weight at the center while maintaining comfortable wear. The center is secured in a refined four to six prong open head, allowing unobstructed light entry to the pavilion and facilitating cleaning access, while the pear diamonds are held in precision prongs that align with the sapphire’s crown angles to create a cohesive optical plane. The open under gallery and precise seat dimensions were engineered to present the sapphire slightly above the band, ensuring optimal exposure to incident light and a balanced silhouette on the hand. Attention to symmetry, prong geometry, and finish are evident in the consistent polish and mirror surfaces of the metal, and the hand setting technique minimizes metal visibility around the girdles for a clean, technical presentation of the gems.

More than a specification, this ring is a study in personality through proportion and material choice, offered by The Natural Sapphire Company. The compact, mixed brilliant cushion and the controlled, intense greenish blue tone speak to an individual who values measured drama and geological authenticity, someone who prefers technical refinement over ostentation. The use of lab grown white pears paired with a natural, heat treated Montana sapphire signals a modern sensibility, a preference for traceable and verifiable choices without sacrificing traditional gemological quality. Craftsmanship traits such as excellent polish, exacting facet junctions, and robust prong engineering appeal to the wearer who appreciates precision, and the ring’s low profile and balanced three stone geometry suit an active lifestyle that still desires elegance. For those who wish to learn more, The Natural Sapphire Company can provide detailed gemological information and bespoke options for metal variations or band adjustments, ensuring the technical specifications and visual character align with personal preference. This ring is a deliberate expression of refinement, combining technical gem cutting, calibrated diamond accents, and purposeful gold work to reflect a wearer who prizes clarity of design and integrity of origin.
