Three Stone Blue Sapphire Ring 3.52 Ct., 18K White Gold

This ring centres a C. Dunaigre certified Blue, 3.52 carat emerald cut blue sapphire, presented in a precisely engineered gallery that accentuates the gem’s architectural geometry. The sapphire measures 8.81 by 7.43 by 4.99 millimetres, its rectangular step facets and clipped corners producing the characteristic interplay of broad light planes and controlled flashes associated with an emerald cut. Evaluated as eye clean at normal viewing distance, the stone shows no internal features that detract from its clarity, and its polish has been graded excellent to ensure crisp facet junctions and a smooth, reflective surface. The colour is described as medium intense, a saturation that balances vibrancy with translucence, and the stone is free of enhancements, an attribute that preserves its natural origin in Ceylon, Sri Lanka. The certified nature of the sapphire and the absence of treatments make it a compelling choice for those seeking an authentic, untreated gem, and the dimensions and cut have been selected to maximise the stone’s presence on the finger while maintaining classical proportions.

The design of the mounting draws inspiration from architecture, with reference to classical cornices and clean modernist lines, while also nodding to natural forms through subtle curvature and the use of half moon side stones that emulate leaf or petal shapes. The sapphire is secured in a four-prong platinum 950 setting that is engineered to provide both security and unobstructed light entry to the pavilion, creating balance between protection and brilliance. Flanking the central sapphire are two white half moon shaped natural diamonds, with a combined weight of approximately 0.40 carats, colour grade E, and clarity graded Very Slightly Included, VS1 and VS2, respectively. These side stones have been calibrated to echo the sapphire’s shoulder lines, their crescent profile softening the angularity of the emerald cut and creating a measured transition from centre stone to band. The half moons are set in carefully contoured bezels and minimal prongs so that they sit integrated to the ring’s silhouette, contributing subtle scintillation that frames the central blue without overpowering it.

The ring is fully crafted in platinum 950, a metal chosen for its density, resilience, and naturally white tone which complements both the blue of the sapphire and the icy white of the diamonds. Platinum’s strength allows for finer claws and a lower profile gallery while maintaining long-term security for the stones, and its hypoallergenic properties suit continual wear. Structurally, the shank tapers gently from the shoulders to the base, providing ergonomic comfort and an architectural sense of proportion, while the gallery features openwork that reduces overall weight and permits additional light to reach the gem pavilions. The approach to finishing is restrained and exacting, with high polish on visible surfaces and satin touches in recessed areas to enhance the perception of depth without drawing attention away from the gemstones. The Natural Sapphire Company name is associated with each stage of the ring’s creation, from the selection of the untreated Ceylon sapphire to the precision setting of the VS clarity half moons, reflecting a practice of documented sourcing and detailed craftsmanship. This ring balances the rigour of architectural form with the softer language of nature, producing a design that reads as purposeful, enduring, and refined.
