Three Stone Blue Sapphire Ring 1.52 Ct., Platinum 950

This ring centers on a 1.52 carat cushion shape blue sapphire, precisely measured at 6.47 x 6.39 x 4.00 mm, cut in a mixed brilliant configuration that balances color depth with scintillation. The mixed brilliant treatment combines a faceted crown optimized for light return with a pavilion geometry designed to preserve saturation, and the result is a stone that exhibits intense blue with controlled flash. The sapphire evaluates as eye clean at typical viewing distances, meaning no inclusions are apparent to the unaided eye while internal features may exist under magnification, and the excellent polish ensures crisp facet junctions and uninterrupted light paths. The gem shows dark color saturation, a desirable characteristic in a high quality Thai origin sapphire, and the heat treatment applied is a stable enhancement commonly used to deepen hue and improve clarity without compromising structural integrity. The cushion outline with softened corners allows the larger facets of the mixed brilliant crown to present broad blue fields, while the slightly deeper pavilion depth retains richness when viewed face up, a combination that yields both visual depth and lively return.

The setting in 14K white gold is engineered to maximize both perceived color and apparent clarity, using precise geometry and metal finish to influence how light interacts with the sapphire. The sapphire is secured in a four prong head that anchors at the corners of the cushion outline, minimizing metal coverage across the table and crown facets to allow unimpeded light entry, while the open under gallery and sculpted seat beneath the pavilion facilitate transmission and reflection of light back through the stone. The white gold surface is highly polished, providing a neutral, reflective surround that reduces absorption of blue wavelengths and creates a crisp white contrast, which in turn enhances the apparent saturation of the sapphire. Flanking the central stone are paired natural half moon diamonds totaling approximately 0.30 carats, graded E in color and VS1 to VS2 in clarity, precisely cut and set to mirror the silhouette of the cushion, the high color grade of the diamonds generates a bright white rim on either side of the sapphire that visually sharpens corner definition and increases perceived contrast, while the very slight inclusions remain inconspicuous under normal wear conditions.

Craftsmanship details underscore how each element was considered to optimize optical performance and long term durability. The prong tips are symmetrically aligned to the pavilion terminating points, ensuring even tension and minimal lateral light obstruction, and the prong shoulders are tapered to blend into the shank so that the eye is drawn to the stone rather than the metal. The half moon diamonds are matched for proportion and table alignment so their brilliancy complements the mixed brilliant crown of the sapphire, and the joinery between head and shoulders is executed with tight tolerances to maintain a low profile and comfortable fit while preserving an adequate clearance for cleaning and light circulation. The choice of 14K white gold provides a balance between strength and lustre, holding settings securely while offering a durable polished surface that reflects and redirects light into the gems. At The Natural Sapphire Company we prioritize facet harmony, precise setting geometry, and finish quality so the interaction between metal and gemstone enhances color intensity, minimizes visual distractions from inclusions, and presents a coherent optical signature that reads as deep, saturated blue with crisp white contrast from the side diamonds. This ring is a technical composition of cut, color, and setting, engineered to present the sapphire at its most vivid and clean in everyday wear.
