This ring is built around a transparent 3.83 carat oval blue sapphire, measured at 11.15 by 7.73 by 5.24 millimeters, presenting a length to width ratio of approximately 1.44 and a depth that produces an effective face up depth near 47 percent. The sapphire has been cut as a mixed brilliant, with a brilliant style crown designed to maximize scintillation and a pavilion that blends facet angles to preserve saturation and control light return. The mixed brilliant faceting enhances both tonal depth and pinpoint sparkle, concentrating blue chroma in the table area while allowing flasher facets to break the surface in movement. Observed at eye level the stone is eye clean, which allows the dark saturation to express as a velvety, even blue rather than as diffusion or cloudiness, and the polish is graded excellent, indicating crisp facet junctions and minimal surface abrasions. Treatment disclosure is clear, the sapphire has undergone standard heat treatment to stabilize tone and clarity, and its documented origin is Australia, a source known for producing sapphires with strong, cool blue character and stable material quality.
The sapphire is surrounded by a halo of natural round white diamonds weighing approximately 1.44 carats total, each stone specified as Very Slightly Included within the VS1 to VS2 range and graded color F. The diamonds are cut as round brilliants, chosen for their ideal facet geometry to deliver white light return and contrast against the sapphire body color. In this halo configuration the diamonds are individually calibrated and matched for diameter and optical performance, creating a contiguous ring of brilliance that defines the pavilion and visually increases the perceived size of the center sapphire while maintaining balanced brightness and color neutrality. The setting architecture pairs 14 karat white gold for the diamond halo and upper basket with 14 karat yellow gold for the shank and lower mounting, a deliberate two tone approach that optimizes contrast and durability. The white gold around the diamonds provides a reflective backdrop to enhance apparent whiteness, while the yellow gold shank offers tensile strength and a warm contrast that complements the deep blue of the sapphire. The mounting is executed with precision hand setting, secure claw prongs that register at facet junctions, a low profile gallery to admit light from multiple angles, and mirror polished surfaces at stress points to minimize wear while preserving aesthetic coherence.
At The Natural Sapphire Company we place equal importance on provenance and craftsmanship, and this ring exemplifies that commitment. The Australian origin of the sapphire is confirmed through our supply chain documentation, and we maintain direct partnerships with responsible miners and accredited intermediaries to ensure traceability. All enhancement treatments are fully disclosed, and the diamonds and precious metals are sourced in accordance with industry best practices to avoid conflict minerals and to support fair labor standards. Where feasible we prioritize recycled gold inventory for use in fabrication to reduce environmental impact, and our bench processes include independent quality checks for solder integrity, prong security, and finish continuity. We also offer detailed gemological reporting on request, which documents measurements, clarity observations, color grading, and treatment history, enabling a transparent purchase decision for technically minded buyers. Care recommendations include routine inspection of prongs and periodic professional cleaning to preserve facet brilliance and to protect the integrity of the mixed brilliant geometry, ensuring that the optical performance specified at purchase endures through regular wear.
