Three Stone Blue Sapphire Ring 4.48 Ct., 18K Yellow Gold

This ring centers a GIA certified, transparent blue sapphire weighing 4.48 carats, presented in a cushion shape with precise dimensions of 10.54 by 7.85 by 6.01 millimeters. The stone has been fashioned with a mixed brilliant cut, a deliberate faceting schema that combines a brilliant style crown faceting pattern with a modified pavilion arrangement to optimize internal light return and dispersion. The crown exhibits a finely faceted table and carefully arranged star and kite facets that increase scintillation, while the pavilion geometry has been calibrated to balance light leakage and color saturation, resulting in evenly distributed brilliance across the table. Clarity has been evaluated as eye clean at typical viewing distances, indicating no inclusions visible to the naked eye, and the polish has been graded excellent, giving crisp facet junctions and high surface reflectivity. The sapphire displays vivid color saturation consistent with high grade Ceylon material, with a strong medium to medium deep tone that enhances the blue violet spectrum, and the stone has been heat treated, a stable and widely accepted enhancement that refines color and clarity while maintaining structural integrity. Origin reporting identifies the sapphire as Ceylon Sri Lanka, a provenance that corresponds to the characteristic bright, lively blue associated with this source, and the GIA certification provides an independent technical record of the gemstone s measured parameters and treatments.

Flanking the central sapphire are white emerald cut shaped natural diamonds totaling approximately 0.66 carats, selected for their crisp facet architecture and optical contrast with the cushion mixed brilliant center. The diamonds are graded Very Slightly Included in clarity, in this instance VS1 and VS2, indicating inclusions that are minor and not expected to affect the clean visual impression when set, and they carry an E color grade, denoting exceptional colorlessness that enhances perceived brightness against the yellow gold mounting. The emerald shaped diamonds have linear step facets that produce a hall of mirrors effect, providing a counterpoint to the scintillation of the central mixed brilliant cut sapphire and creating a composed transition of light. The mounting is executed in 18 karat yellow gold, chosen for its warm hue that complements and intensifies the sapphire s blue, and the metal work demonstrates exacting craftsmanship, including a four claw prong system for secure retention of the center stone, precisely tapered shoulders to visually balance the proportions, and an open under gallery to facilitate light ingress and ease of cleaning. All seatings and bezel clearances have been finished to tolerances that ensure even pressure distribution, and the surfaces are hand finished to a high polish that matches the gem polishing grade, producing a coherent ensemble between metal and stones.

As an engagement or wedding piece this ring functions both as an object of refined gemological specification and as a durable emblem intended for daily wear. Sapphires rate nine on the Mohs hardness scale, a factor that supports longevity and resistance to abrasion for a central gemstone expected to be worn continually, and the heat treatment applied to this sapphire is a stable enhancement that will not compromise the stone s performance in normal use. The three stone aesthetic embodied by the main sapphire and the two emerald shaped side diamonds lends itself to layered symbolism, allowing wearers to interpret the composition as past present and future, or as partner memory and continuing promise, while the careful color and clarity grading ensures the ring communicates luxury without visual distraction from inclusions or color zoning. The Natural Sapphire Company offers this ring with full certification documentation and expert advisory on sizing and maintenance, and the piece is constructed to accommodate routine professional cleaning and periodic inspection to maintain prong security and polish. For purchasers who prioritize measured gemological criteria, provenance, and artisanal setting technique in an engagement or wedding emblem, this ring represents a technical and aesthetic synthesis, combining a GIA certified Ceylon sapphire of vivid saturation and excellent polish with colorless, well graded emerald shaped diamonds, all mounted in warm 18 karat yellow gold to create a timeless commitment ring suitable for daily wear and heirloom transmission.
