Three Stone Blue Sapphire Ring 0.86 Ct., Platinum 950

This ring centers on a transparent 0.86 carat marquise shape blue sapphire, with precise dimensions of 8.01 by 4.13 by 3.12 millimeters, cut in a mixed brilliant style to balance strong color return with lively scintillation. The marquise proportions yield a length to width ratio that emphasizes the stone elongation, creating an elegant table face and a silhouette that increases apparent coverage on the finger. The mixed brilliant faceting combines a carefully faceted crown with pavilion faceting optimized to return light while maintaining color saturation, and the overall polish has been evaluated as excellent, producing crisp facet junctions and smooth facet planes. At eye level the sapphire is eye clean, free of inclusions visible without magnification, which allows the intense blue saturation to read strongly and evenly across the table. This specimen exhibits the hallmarks of a high quality Ceylon sapphire, including lively pleochroism that can present slightly different blue tones at differing angles, and its classic Ceylon provenance contributes to the vivid, clean blue that collectors associate with Sri Lankan material. Heat treatment has been applied to improve clarity and to stabilize the color, this being a standard, permanent enhancement accepted within the trade, and one that has been fully disclosed.

Flanking the marquise are white round natural diamonds, with a combined weight of approximately 0.07 carats, each stone selected for a balance of brilliance and optical purity. The side diamonds are graded Very Slightly Included in the VS1 to VS2 range, with a color grade of F, which provides a high level of white body color that complements the cool tone of the 14K white gold setting. These diamonds are cut to small brilliant standards appropriate for accent roles, producing tight scintillation that frames the sapphire rather than competing with it. The diamonds are set in secure prongs adjacent to the sapphire, positioned to enhance light entry into the sapphire pavilion and to create contrast that visually sharpens the sapphire silhouette. The mounting is executed in 14 karat white gold, chosen for its balance of durability and neutral color, with a polished finish that reflects light up into the gem platform and maintains a low profile on the hand for daily wear.

From a gemological and design perspective, the marquise mixed brilliant cut on this piece has been proportioned to maximize apparent color while minimizing common marquise issues such as excessive bow tie effect. The cutter has managed crown angle and table size to concentrate saturated blue in the face up view, while the pavilion facet architecture disperses light into controlled flashes that animate the stone during movement. The depth relative to the average of the length and width has been maintained in a range that sustains strong face up weight distribution and readability of color, without creating a dark appearance in low lighting. The excellent polish accentuates the facet reflections and the crispness of the mixed brilliant pattern, and the symmetry of the cutting preserves consistent optical performance on both lobes of the marquise. Together with the eye clean clarity grade, these cutting considerations yield a gem that reads as a vivid, lively blue from every common viewing angle, a quality combination for connoisseurs who value both color saturation and optical performance.

The historical and provenance narrative further enhances the ring value, both emotionally and technically. Ceylon, or Sri Lanka, has been a primary source of sapphires for centuries, with a lineage of local mining and cutting traditions that produced some of the most sought after cornflower and intense blues in the marketplace. Sapphires from this island are prized for their clarity and lively, saturated blues, and the association with Ceylon provides an additional layer of desirability for collectors. At The Natural Sapphire Company we document origin, enhancement, and cutting details because provenance, disclosure, and craftsmanship create measurable market confidence. The use of a period appropriate marquise silhouette together with ethically sourced Ceylon material and responsibly graded side diamonds, set in a finely finished 14K white gold mounting, communicates a complete story of geology, human craft, and provenance. For a knowledgeable buyer, this narrative translated into technical attributes, the sapphire weight and proportions, the mixed brilliant faceting strategy, the eye clean clarity, the intense Ceylon blue, the small but high quality diamond accents, and the finished 14 karat white gold setting, coalesce into a purchase that is both an aesthetic statement and a technically defensible investment.
