Accent Stones Bi Color Sapphire Ring 1.49 Ct., 18K Yellow Gold

This ring centers a transparent 1.49 carat emerald cut bi color sapphire, hand selected and precisely matched to the design ethos of The Natural Sapphire Company. The sapphire measures 7.10 millimeters by 5.46 millimeters by 3.90 millimeters, with a depth of approximately 54.9 percent, dimensions that yield a balanced table to depth relationship ideal for step faceting. The gem exhibits medium intense color saturation, with the bi color nature manifesting as a subtle transition across the pavilion and crown when viewed from different angles. Clarity is graded very slightly included when evaluated at eye level, and the cut displays the defining long rectilinear facets of the emerald shape, executed to emphasize parallel step facets and broad facet planes. The stone is untreated, no enhancement, and its origin is Ceylon Sri Lanka, a provenance known for producing sapphires with clean crystalline structure and stable color distribution. The excellent polish on all facet junctions enhances the sapphire surface lustre, producing crisp facet reflections that are characteristic of a well executed step cut.

The emerald cut itself is integral to the visual performance of this bi color sapphire, because the step facet architecture creates broad planes which act as mirrors and reveal internal color zoning with clarity. The crown facets are proportioned to allow measured light ingress through the table, while the pavilion steps are calibrated to return light in broad flashes rather than scintillation, maintaining the dignified appearance unique to step cuts. The 7.10 millimeter length against a 5.46 millimeter width yields a classic emerald ratio that supports symmetry and minimizes windowing, preserving color in the face up view. Internal inclusions described as very slightly included are positioned and oriented so as not to interfere with the centered colour transitions, and the excellent polish reduces surface diffusion of light, keeping facet edges sharp. Because the sapphire is natural and unheated, its medium intense saturation remains stable, and the facet design intentionally showcases the bi color character as a sophisticated, controlled effect rather than an irregular patching of tone.

The setting technology is designed to frame and elevate the emerald cut sapphire, using an octagonal bezel that traces the stone outline and reads as an architectural collar around the crown, giving the gem a precise visual boundary while protecting the girdle. The bezel walls are engineered with a slight inward bevel, a deliberate geometry that guides light into the pavilion flanks and directs reflected light back through the table, thereby enhancing perceived depth. The bezel seat is machined to micrometer tolerances to ensure even pressure distribution around the stone, preserving facet alignment and preventing stress concentrations. Supporting diamonds are straight baguette shapes, totaling approximately 0.40 carats, mounted into a tight channel along the shoulders. These baguettes are natural white diamonds, clarity graded VS1 and VS2, color grade F, and they are cut with linear step facets that harmonize with the emerald cut sapphire. The channel setting is executed with discrete rails that hold the stones flush to the band, minimizing metal exposure and creating a continuous optical flow from the shoulders into the central bezel. The result is a measured contrast between the warm yellow gold and the cool white of the diamonds, balanced so the baguettes function as light directors that emphasize the sapphire table rather than compete with it.

Craftsmanship of the mounting is realized in 18 karat yellow gold, chosen for its warm hue which subtly enriches the bi color tones of the sapphire and complements the cool white of the baguette diamonds. The gold is hand finished to a high mirror polish, with chamfered inner edges on the bezel and softly rounded inner band for comfort fit. The bezel thickness is calibrated to provide protection without obscuring the crown facets, and the undergallery is shaped with open arcs to permit both cleaning access and additional light entry to the pavilion, a careful balance between security and optical performance. All diamond channels are set with consistent bed depth and side wall parallelism, and the baguette lengths are matched to maintain uniformity of line when observed in profile. Every junction is inspected and finished to the exacting standards associated with The Natural Sapphire Company, and the ring is intended for collectors and connoisseurs who value technical precision in faceting and setting. For those who appreciate the interplay of geometry, light, and material, this ring presents a study in how detailed setting techniques make a step cut sapphire resonate, while ensuring long term durability and aesthetic restraint.
