Studs Blue Sapphire Earring 1.69 Ct.Tw.Total Carat Weight, Platinum 950

This pair of cushion shape blue sapphires presents a precisely calibrated combination of size, cut, and origin, resulting in exceptional visual appeal and technical refinement. The set totals 1.69 carat weight, each stone weighing approximately 0.845 carats, and the measured dimensions are 5.77 by 5.27 by 3.14 millimeters. The stones are cut to a mixed brilliant facet architecture, and they exhibit vivid color saturation with a clarity grade of very slightly included evaluated at eye level. The polish on each pavilion and crown facet is graded excellent, which preserves crisp facet junctions and maximizes internal light return. Origin is Ceylon Sri Lanka, a source renowned for sapphires that combine lively color with a fine crystalline structure. The proportional depth of the stones calculates to approximately fifty seven percent, a depth that balances strong color saturation with efficient light return, particularly important for medium to medium deep tone sapphires.

Technically, the mixed brilliant cut on these cushions integrates a brilliant crown facet scheme with a modified pavilion, a configuration that creates a dynamic interplay between scintillation and color saturation. The crown faceting distributes small, highly reflective facets across the table and star areas, producing lively white light flashes when the wearer moves, while the modified pavilion planes control the path of light to deepen perceived color without sacrificing brightness. The excellent polish reduces microsurface diffusion, so light transmission through the table and girdle is clean, and facet junctions remain sharp, increasing contrast and perceived clarity. The very slightly included clarity grade, assessed at eye level, means inclusions are minimal and do not materially interrupt light paths, allowing the vivid blue saturation to read strongly across the table in both direct and oblique viewing angles.

The mounting is executed in eighteen karat white gold, engineered to support and enhance the optical characteristics of the stones while meeting standards of durability and daily wear. Each sapphire is secured in a four prong setting with a low profile basket and an open gallery that permits unobstructed access to pavilion facets from the back and the sides. The prongs are sized to minimize metal coverage across the crown while maintaining secure claws that are carefully burnished and tipped to prevent touching facet surfaces. Posts are configured with precision turned threads and friction backed butterflies to provide stable orientation and even pressure distribution through the piercing, reducing the risk of micro movement that can degrade light return over time. The white gold is finished to a high mirror polish, and where applied, a bright white surface treatment enhances the cool metal tone so that it complements the blue saturation without competing for visual dominance.

The design and setting work together to amplify the natural beauty of the Ceylon sapphires, a balance of optical engineering and fine metalwork that is characteristic of The Natural Sapphire Company. The open gallery and minimal prong footprint allow light to enter the pavilion and reflect back through the crown, intensifying the vivid blue while preserving the mixed brilliant cut scintillation. The cool white sheen of the gold acts as a neutral reflector, enhancing perceived contrast at facet edges and making the blue appear more saturated and vivid in varied lighting conditions. Symmetry matching and meticulous hand setting ensure that the pair reads as a single statement when worn, with matched color, cut proportions, and visual weight. For collectors and connoisseurs who appreciate exacting craftsmanship, these earrings deliver a technically informed expression of color, cut, and secure, elegant mounting, and The Natural Sapphire Company stands behind the selection and finishing of each component.
