Solitaire Bi Color Sapphire Ring 1.38 Ct., 18K Yellow Gold

This ring centers on a transparent 1.38 carat oval shaped bi color sapphire, measuring 7.89 by 5.92 by 3.91 millimeters, cut to a mixed brilliant architecture that balances scintillation with color depth. The mixed brilliant approach employs a brilliant style crown to maximize light return through multiple small star and kite facets, paired with a modified pavilion geometry that preserves color zoning and enhances depth without sacrificing sparkle. The length to width ratio of approximately 1.33 yields a classically elegant oval silhouette, and the overall depth of 3.91 millimeters corresponds to a well proportioned pavilion that sits at about 56.6 percent of the average diameter, a profile that promotes even light distribution and minimizes windowing while allowing the bi color character to read consistently from multiple angles.

Color and clarity are documented with technical precision, the sapphire showing light color saturation and exhibiting a distinct bi color effect that transitions across the table as the stone is rotated. The two tone presentation benefits from the faceting scheme, where the crown facet angles are optimized to refract and scatter light in such a way that the cooler blue zones and the warmer greenish yellow zones remain balanced, rather than one washing out the other. Clarity has been evaluated as very slightly included at eye level, indicating that inclusions are minor, typically fine crystals or needles confined to localized areas and not affecting the overall transparency or brilliance. The polish is excellent, with crisp facet junctions and a smooth girdle finish, which together allow for strong light return and a high degree of polish lustre without surface abrading that would disrupt the visual flow of the color zones.

The mounting is executed in 14 karat yellow gold, a choice that complements the warm component of the sapphire and provides a stable, durable setting suitable for everyday wear. The design reads as a refined solitaire, with four tapered claw prongs that secure the oval pavilion and crown while keeping the profile relatively low to moderate, allowing the gem to sit close to the finger. The gallery is open and sculpted, incorporating a delicate pierced framework beneath the crown that increases light entry into the pavilion and facilitates cleaning access, while maintaining structural integrity. The shank is slim and rounded, transitioning into a tapered shoulder that funnels the eye to the center gem, the entire piece finished to a high polish to reflect light against the sapphire, and to create a smooth mating surface for stacking with bands.

This ring is engineered to serve as both a standalone statement and a component in a stacked configuration, its proportions and construction making it versatile for multiple styling strategies. Worn alone, the mixed brilliant cut sapphire occupies center stage, its balanced depth and crown facet structure delivering a combination of scintillation and color shift that reads distinctly in ambient and directional light. For stacking, the slim shank and modest crown height allow adjacent bands to sit flush without creating uncomfortable gaps, and the tapered shoulder offers a natural nesting point for curved or straight bands. The open gallery and low profile also permit pairing with wider bands without obscuring the pavilion, and the yellow gold palette harmonizes with both matching yellow gold bands and contrasting metals when a mixed metal stack is desired.

Provenance and craftsmanship are integral to this offering from The Natural Sapphire Company, the sapphire originating from Ceylon, Sri Lanka, a source known for producing stones with fine tone and lively color dynamics. The cutting approach reflects careful lapidary decision making, prioritizing both optical performance and the preservation of the stone material, and the setting fabrication adheres to standards that balance form with function. For the technically minded buyer, the combination of a well calculated depth percentage, a mixed brilliant faceting scheme, eye level very slightly included clarity, and excellent polish constitute a gem and mounting designed to deliver reliable performance over time, with the resilience of sapphire on the Mohs hardness scale and the durable alloy properties of 14 karat yellow gold. Care recommendations include routine cleaning to maintain polish and clarity, and occasional inspection of the prongs and gallery to ensure continued security and alignment when worn in daily stacked ensembles.
