Three Stone Blue Sapphire Ring 3.04 Ct., 18K White Gold

This ring centers a transparent 3.04 carat emerald cut blue sapphire, with dimensions 8.92 x 7.29 x 4.76 mm, exhibiting a length to width ratio of approximately 1.22 to 1, and a depth of approximately 59 percent. The sapphire has been cut to the classic step cut geometry, with broad table, concentric step facets on the crown and pavilion, and subtly truncated corners that emphasize the stone geometry rather than brilliance scintillation. The faceting displays precise parallel alignment and strong facet junctions, producing the characteristic hall of mirrors effect associated with top quality emerald cuts, while maintaining even light return across the table and along the step planes. The material is eye clean at typical viewing distances, with vivid color saturation consistent with fine Ceylon, Sri Lanka origin, and an excellent polish that results in crisp facet edges and minimal surface luster disruption.

Flanking the center sapphire are white trapezoid natural diamonds totaling approximately 0.50 carats, with clarity grades of VS1 and VS2, and a color grade of G. The trapezoid facets mirror the step lines of the sapphire, their modified step faceting and tapered geometry serving to visually extend the center stone and reinforce the rectangular axis. The diamonds are calibrated to sit in precise shoulder seats, their pavilion and girdle alignment matched to the sapphire to preserve symmetry and optical flow. The entire composition is set in platinum 950, executed with four high precision prongs for the center and tailored mounts for the side stones, an open gallery to enhance upward light ingress, and a uniform polish on the shank to complement the stone finishes. The Natural Sapphire Company has specified exacting tolerances in seat angles, prong thickness, and stone centering to ensure long term stability and optimal light performance, making this piece a technically rigorous example of step cut faceting married to classical three stone design.
