Celtic Bluish Green Sapphire Ring 0.92 Ct., Platinum 950

This ring centers a transparent 0.92 carat trillion shape sapphire, precisely faceted to 5.87 by 6.25 by 3.86 mm, cut in a classic trillion configuration to maximize table area and light return. The pavilion and crown angles are proportioned to emphasize a strong center flash and to produce well distributed scintillation across the three lobes of the stone. Clarity grade is slightly included, evaluated at eye level, with small natural internal features that do not dominate the visual field and that are consistent with the provenance. Color presents as a bluish green with intense saturation, the tone balanced to sit between vivid blue and deeper teal, and the surface polish records an excellent grade, yielding clean facet junctions and crisp facet reflections. The sapphire originates from Montana and has undergone a standard heat treatment to stabilize color and reduce the visibility of microscopic mineral inclusions, a disclosed enhancement that is common for material from this region, and one that preserves the natural origin while enhancing optical performance.

The trillion cut in this piece is executed to emphasize symmetry and optical stability, each of the three main facets aligned to produce uniform light return and consistent pleochroic behavior as the stone is rotated. Facet polishing is excellent, ensuring minimal surface diffusion of light and maintaining strong contrast between bright and dark facet faces for perceived depth. The crown is proportioned to open the table sufficiently for color assessment under normal lighting, while the pavilion depth is calibrated to avoid a washed out face color, conditions that are especially important in bluish green sapphires where tone and saturation interact. Slight internal features, present as part of the slightly included clarity grade, act as natural light scattering centers in some viewing angles, creating secondary flashes without materially reducing overall transparency. The result is a sapphire that performs with lively brilliance, stable color saturation, and a textured internal character that affirms its natural origin and Montana provenance.

The entire mounting is executed in 14K white gold, chosen for its combination of strength and wearability, making this design suitable for long term daily use. The 14K alloy contains approximately 58.3 percent gold with the remainder in durable alloying metals, yielding a hardness and tensile strength superior to higher karat alloys, and reducing risk of deformation under typical wear conditions. The ring employs a three prong secure setting tailored to the trillion geometry, each prong positioned to cradle the stone at the primary lobes, and engineered with sufficient mass to resist bending while maintaining a refined appearance. The shoulders incorporate open work and interlaced motif elements that distribute stress away from the seat, while the undergallery is engineered to clear the fingertip plane and to avoid pressure points, preserving comfortable long term wear. In practical terms the 14K white gold construction will retain structural integrity through normal daily activity, and routine maintenance such as periodic inspection and professional re tipping of prongs will extend service life for decades.

At The Natural Sapphire Company we emphasize material disclosure and fabrication standards, and this ring is presented with full transparency regarding origin and treatment, along with measured dimensions, precise weight, and observed clarity. The piece is ideal for buyers who appreciate technical craftsmanship, with a focus on faceting geometry, polish quality, and the mechanical advantages of a 14K white gold mounting. For conservation and to preserve the polish, we recommend regular cleaning with warm water and a mild detergent using a soft bristle brush, and avoidance of harsh chemical exposure that can affect surface finish, while scheduling professional inspections annually for prong tightness and structural condition. Custom services are available for alternative metal choices or additional reinforcement features if desired, and our team can provide detailed diagrams and magnified imaging to assist in evaluation prior to purchase. This Montana sapphire in a meticulously executed 14K white gold setting represents a balance of natural character, optical refinement, and durable construction suited to both connoisseurship and everyday wear.
