Pave Blue Sapphire Ring 4.59 Ct., 18K White Gold

This ring centers a C.Dunaigre certified Vivid Blue oval sapphire, weighing 4.59 carats, with dimensions of 10.44 by 7.89 by 6.70 millimeters and a mixed brilliant cut that maximizes color and brilliance. The stone displays vivid color saturation, an excellent polish, and a clarity grade described as very very slightly included when evaluated at eye level. The sapphire is heat treated and originates from Ceylon Sri Lanka, a source known for richly saturated blue material. Surrounding the center are white round natural diamonds totaling approximately 1.32 carats with clarity grades of VS1 and VS2 and a color grade of F, together with additional white round natural diamonds totaling approximately 0.65 carats with clarity VS and color grades of F to G. The ring is fully set in platinum nine hundred fifty, constructed with a prong set halo and pavé set diamonds along the shank, combining visual impact with structural support.

In terms of durability this design benefits from both the inherent hardness of sapphire and the robustness of platinum nine hundred fifty. Sapphire rates nine on the Mohs scale, making it markedly more resistant to scratching than many competing center stones used in comparable halo rings, such as emerald, aquamarine, or tanzanite. The platinum nine hundred fifty setting offers greater resistance to wear and superior tensile strength compared with equivalent designs in fourteen or eighteen karat gold, allowing finer prongs and tighter settings that retain stones more securely over time. Compared to bezel set or low profile designs a prong halo offers more light return at the cost of slightly increased exposure of the center stone edges, however the dense platinum construction and well formed prongs reduce the risk of deformation and loss. Small pavé diamonds are more exposed than channel set stones and require routine inspection, nevertheless the VS clarity and F to G color of the diamonds reduce the likelihood of damage resulting from inclusions. For a similar looking halo engagement ring on the market this piece from The Natural Sapphire Company typically provides superior long term structural stability, particularly versus designs in softer metals or with more fragile center gems, while retaining the brilliance and refined silhouette expected of high quality sapphire and diamond jewelry.
