Three Stone Bluish Green Sapphire Ring 4.58 Ct., 18K White Gold

This ring centers on a 4.58 carat cushion shape bluish green sapphire, measured precisely at 10.02 x 8.96 x 5.39 mm, cut as a mixed brilliant, and originating from Ceylon Sri Lanka. The mixed brilliant approach pairs a brilliant facet arrangement on the crown with a modified pavilion geometry, balancing broad table reflections with deep internal scintillation, and yielding a lively interplay between flash and sparkle across the pavilion facets. The gem displays vivid color saturation and an even distribution of hue, the bluish green character indicating a primary blue component with a balanced green modifier, which contributes to both depth and adaptability under different lighting. The gem was evaluated as eye clean at standard viewing distances, and an excellent polish enhances facet crispness and light return, while the cut depth relative to the average girdle diameter gives a well proportioned profile, approximately 56.8 percent, that maximizes brilliance without sacrificing weight retention in the pavilion.

Flanking the center sapphire are white half moon shaped lab grown diamonds, totaling approximately 1.20 carats, selected for their color grade F and clarity grades in the VS1 and VS2 range. The half moon silhouette is executed with precision to mirror the curve of the cushion outline, the tapered shoulders of each crescent aligning to create continuous optical flow from center to side. Each half moon uses a dense brilliant facet set on the crescent surface to deliver white light return and to frame the sapphire with spectral contrast, while trimmed girdles and consistent facet junctions ensure secure settings and minimal shadowing at the junction with the central stone. The lab grown origin allows for rigorous control of crystal growth and facet orientation, producing consistent scintillation and predictable optical performance in matched pairs, and the VS clarity range keeps internal characteristics minor and local, preserving clean windows into the sapphire without distracting pinpoints.

The mounting is crafted in platinum 950, chosen for its mechanical strength, natural white tone, and long term wear characteristics that support repeated cleaning and maintenance without loss of mass. The setting employs precisely milled prongs that engage the sapphire at structurally favorable anchor points on the girdle, each prong tipped and hand burnished to avoid abrasion to the pavilion edges while maintaining low visual intrusion. The half moons are set in paired shoulder settings that are integrated into a reinforced gallery structure, the under gallery incorporating triangulated openwork for optimized light circulation and to reduce unnecessary metal mass beneath the pavilion, improving perceived size and lift of the center gem. All metal surfaces receive sequential hand finishing and polishing, with particular attention to the junctions where prongs meet the shank to ensure flush seating, minimal snag potential, and crisp profile lines that complement the geometric restraint of the cushion and crescent forms.

Beyond material specifications and technical execution, the ring is a considered exercise in symbolism and enduring design language, articulated and guaranteed by The Natural Sapphire Company. The three stone arrangement, with a substantial central sapphire flanked by supportive crescents, reads as past, present, and future, a temporal narrative rendered in refractive geometry. The cushion shape carries an historical resonance, its softened corners and pillow outline suggesting vintage lineage, while the mixed brilliant cutting strategy modernizes that silhouette with dynamic light performance, creating a dialogue between tradition and contemporary craft. The bluish green hue embodies balance and renewal, blue suggesting fidelity and green suggesting growth, together communicating a commitment that is both steadfast and evolving. The platinum 950 setting reinforces that message of permanence, its density and hue providing a neutral and durable frame that will preserve optical relationships for generations. In technical terms this ring unites precise lapidary control, matched facet geometry in the side diamonds, and thoughtful metallurgical choices, all assembled to produce a jeweled object that reads as both a rigorous piece of gemological engineering and a carrying symbol of continuity and support.
