Three Stone Blue Sapphire Ring 3.11 Ct., 18K White & Yellow

This ring centers a remarkable, transparent GUBELIN certified blue sapphire, 3.11 carats, cut in a radiant shape with precise dimensions of 8.39 by 6.74 by 5.49 millimeters, and presented with an excellent polish that enhances its faceting and light return. The sapphire exhibits intense color saturation and has been evaluated as eye clean at normal viewing distance, a clarity grade that indicates the absence of inclusions visible to the unaided eye, which is a key attribute for any connoisseur assessing overall beauty and durability. The stone has been heat treated, a widely accepted and documented enhancement that improves color uniformity and can refine clarity, and this treatment is fully disclosed and consistent with best practices in responsible gemstone trade. GUBELIN certification accompanies the sapphire, providing an independent, respected laboratory confirmation of the gem attributes and identity, and The Natural Sapphire Company stands behind the provenance and documentation that are essential for both aesthetic enjoyment and long term confidence in value.

The origin of this sapphire, Ceylon, Sri Lanka, is central to its appeal and to its market significance, because Ceylon sapphires hold a distinct and historically esteemed position among gem sources. Sapphires from Sri Lanka are frequently prized for their vivid, lively blues that often combine depth with a bright, slightly violet tinged overtone, a color quality that collectors and gem specialists often describe as possessing both vitality and elegance. Geologically, Sri Lankan sapphires commonly form in alluvial deposits and are influenced by trace elements, principally iron and titanium, which interact in the crystal lattice to produce the rich blue hues admired in high quality stones. When a gemstone of this caliber is accompanied by a GUBELIN report that accepts Sri Lankan origin, educated buyers can rely on that origin as an indicator of classic color character and a long history of fine sapphires from the region, which in turn affects desirability among collectors and informed purchasers.

Complementing the central sapphire, the ring features white half moon shaped natural diamonds, totaling approximately 0.40 carats, graded in clarity as Very Slightly Included, VS1 and VS2, and in color as F. These diamonds are selected to offer a clean, brilliant flank to the radiant sapphire, their precise half moon geometry creating a soft transitional silhouette that enhances the center stone without overpowering it. The VS clarity range signifies small, generally inconspicuous inclusions visible only under magnification to a trained eye, and an F color grade indicates near colorless material that contributes to a bright, neutral contrast alongside the blue sapphire. The combined optical effect is carefully considered, with the diamonds increasing perceived brightness and framing the sapphire to emphasize its color saturation and scintillation, while the quality grades ensure the accent stones provide refinement rather than distraction.

The mounting is executed in a sophisticated two tone approach, using 18K white gold around the head to complement the cool blue and the white diamonds, and 18K yellow gold for the band to introduce warmth and classic presence. This choice of metals balances contrast and harmony, 18K gold offering a high proportion of gold for enduring color and luster, while maintaining sufficient alloy content for structural integrity required by fine prong work and secure settings. Craftsmanship matters as much as the gemstones themselves, and the design here focuses on setting security, light access to the pavilion of the sapphire, and comfortable wear. For the educated buyer, the combination of a certified Sri Lankan sapphire of substantial carat weight, eye clean clarity, intense color, and complementary natural diamonds in a considered two tone 18K mounting makes this ring a statement piece that blends gemological credibility with wearable elegance.
