Accent Stones Blue Sapphire Ring 1.50 Ct., Platinum 950

This ring centers on a transparent 1.50 carat oval Ceylon sapphire, precisely cut to dimensions of 6.84 x 5.97 x 4.50 mm, executed in a mixed brilliant facet layout. The mixed brilliant approach combines the classical elongated oval silhouette with a brilliant facet arrangement on the crown and a carefully calculated pavilion facet pattern, producing a controlled balance between face up color and internal light return. The crown faceting features a well proportioned table and crown angle that cooperate with the pavilion depth to optimize fire and scintillation while maintaining a natural, light color saturation. The sapphire is graded as slightly included when evaluated at eye level, and the excellent polish enhances the interaction of light with each facet junction, producing crisp facet edges and minimal surface diffusion. Sourced from Ceylon Sri Lanka, the stone displays the signature clarity and lively tone associated with that origin, while the mixed brilliant design allows the subtle blue to read as lively and clean under a range of lighting conditions.

Precision in faceting is evident in the distribution and alignment of facets across both crown and pavilion. The mixed brilliant structure incorporates a symmetrical arrangement of kite and star facets on the crown, meeting at a proportionate girdle that anchors the pavilion facets. This controlled geometry ensures that each facet intersection is defined, allowing for repeatable refraction paths and consistent return of white light and dispersive colors. The pavilion facets are aligned to prevent light leakage and to support measured scintillation when the ring moves. Attention to facet junction polish and symmetry minimizes optical disturbances that might otherwise mask the sapphire s natural tone. The excellent polish rating for the sapphire confirms meticulous final finishing, which reduces surface abrasion and maintains sharp facet lines that are essential for both brilliance and longevity.

The supporting diamonds are selected and cut to complement the sapphire s optical behavior. Two white marquise shaped natural diamonds weighing approximately 0.32 carats total are positioned to frame the sapphire, their elongated brilliance enhancing the oval silhouette while contributing directional sparkle. The marquise facets are tuned to direct flash and scintillation toward the center stone, reinforcing perceived brightness without overpowering the sapphire s color. Additional white round shaped natural diamonds, weighing approximately 0.05 carats and 0.072 carats, are set as accent stones. All diamonds are graded Very Slightly Included, clarity categories of VS1 and VS2, and color grade F. These combinations of cut, clarity, and color provide clean, white light return that contrasts and complements the sapphire s subtle coloration, and the facet arrangements of the diamonds are matched to the central stone to create cohesive light dynamics across the ring.

The setting and metalwork are executed in 18K white gold, chosen for its cool tone and strong supportive properties. The prong and gallery design holds the sapphire securely while exposing the pavilion and crown so that light may enter freely. Prong placement is measured to minimize obstruction of the sapphire s crown facets, and the seat is crafted to maintain proper girdle orientation, which is critical to the mixed brilliant geometry. The diamonds are set with precise spacing and secure claws that align the marquise and round facets to the optical axis of the sapphire, enabling coordinated reflections and scintillation. The ring s proportions were calculated to balance wearability with optical performance, ensuring that the metal does not dominate the visual field or inhibit the intended light paths through the central sapphire and its diamond companions.

Every aspect of fabrication reflects the emphasis on faceting precision and optical harmony, from the initial rough selection through to final inspection. The Natural Sapphire Company s approach integrates gemological assessment, lapidary standards, and bench setting discipline, resulting in a piece where the sapphire s mixed brilliant cut performs predictably in diverse lighting. The slightly included clarity at eye level is managed through facet placement that masks internal features while highlighting the stone s luster and tone. The excellent polish across both sapphire and diamonds secures crisp facet junctions and maximum light return. The overall design, with its marquise and round diamond accents and an 18K white gold setting, is engineered to present the sapphire s measured color saturation and to showcase the precise faceting that defines its brilliance and presence.
