Antique Style Blue Spinel Ring 1.60 Ct., 18K White Gold

This platinum 950 ring from The Natural Gemstone Company centers a transparent 1.60 carat cushion shape blue spinel, a gem that combines material resilience with refined optical performance. The spinel measures 6.56 by 6.22 by 4.55 millimeters, producing a depth to average diameter ratio of approximately 71 percent, a proportion that contributes to a deep visual presence while maintaining balanced light return. The stone is fashioned in a mixed brilliant cut, which integrates a modified brilliant crown with a structured pavilion, a configuration chosen to maximize scintillation and color dispersion in a cushion outline. Clarity is graded as very slightly included when evaluated at eye level, meaning the inclusions are minimal and do not disrupt the faceting symmetry or surface integrity. Color saturation is medium, presenting a serene blue that reads consistently in natural and artificial light, and the polish is excellent throughout, ensuring the pavings and facet junctions remain crisp and free of polish lines or abrasions.

The mixed brilliant faceting in this cushion spinel is executed to emphasize both brilliance and face up color. The crown facets are set to modern brilliant angles to fragment incident light into numerous return paths, while modified pavillion faceting supports a controlled windowing effect that enhances perceived color without sacrificing brightness. Facet junctions are consistent across the girdle, which is crucial for even light performance in a cushion shape where corner angles can otherwise create leakage. The excellent polish enhances specular reflection and internal flash, and the medium color saturation situates this stone in a range where fire is apparent without overwhelming the overall tone. The result is a stone that exhibits lively scintillation on movement, layered flashes of blue depth from centrally oriented pavilion facets, and a clean surface presentation that responds predictably to directional lighting during inspection.

The mounting is crafted in platinum 950, an alloy composed of 95 percent platinum and small complementary metals, chosen for its density, ductility, and long term wear characteristics. The gem is secured by a four claw setting that is engineered to support the cushion corners, dispersing impact stress away from the most vulnerable points of the girdle, while the claw profiles are tapered to balance security with light admission. The gallery incorporates openwork filigree that reduces contact with the stone pavilion and allows light to regenerate from beneath, while providing structural bracing between the shoulders and the central head. Shoulder detailing is executed with refined hand finishing, including delicate milgrain edging along the bezel lines and precise engraving in the transition zones, techniques that are labor intensive but that enhance both cosmetics and the tactile feel of the mounting. All joints are finished with controlled solder flow and seamless polishing to avoid stress risers, and the prongs are burnished to the pavilion girdle line to prevent stone movement over repeated cycles of wear.

Durability for daily wear is a primary design consideration for this piece, and both material selection and construction reflect that priority. Spinel registers 8 on the Mohs hardness scale, placing it among gems that resist abrasion from everyday contacts while maintaining good toughness against chipping. The mixed brilliant cut reduces acute facet angles that can expose cleavage planes, this coupled with the corner protective prong design minimizes vulnerability during routine activity. Platinum 950 offers superior metal fatigue resistance, it is highly resistant to corrosion, and it maintains mass rather than thinning away with surface polishing, characteristics that make it ideal for a ring intended for continuous wear. Practical details such as a moderate head height and smoothly rounded internal band edges reduce snag risk and increase comfort for prolonged daily use. For maintenance we recommend periodic checks of prong tightness and occasional professional cleaning and re polishing, steps that preserve both the optical performance of the spinel and the finish of the platinum, and The Natural Gemstone Company provides a full aftercare service to ensure this ring functions as an enduring piece of jewelry across years of wear.
