Antique Style Blue Sapphire Ring 4.18 Ct., 18K White & Yellow

This ring centers on a transparent GRS certified Blue sapphire weighing 4.18 carats, presented in an oval shape with dimensions of 11.50 by 9.20 by 4.10 millimeters and a mixed brilliant cut. The stone displays an eye clean clarity as evaluated at eye level, and it carries a dark color saturation with an excellent polish that emphasizes the depth and velvety quality of the blue. Origin is documented as Thailand, and the GRS certificate provides independent verification of the sapphire identity and origin. The mixed brilliant cut combines pavilion facets optimized for return of light with a crown arrangement that enhances face up brilliance, and the oval proportions offer a balanced presentation that reads larger on the finger while retaining a classic silhouette.

Surrounding the central sapphire is a precision set halo of white round shaped lab grown diamonds, with a combined weight of approximately 1.80 carats, clarity grading of Very Slightly Included VS1 VS2, and a color grade of F. These diamonds have been selected for consistent performance and visual harmony, and their bright white hue is deliberately set in a white gold head to maximize contrast and scintillation against the blue center stone. The diamonds are individually mounted to ensure even spacing and stability, and the mixed use of white gold for the head and yellow gold for the shank provides a considered aesthetic balance. The metals employed are 18K white gold and 18K yellow gold, chosen for their combination of precious metal purity and suitability for fine setting work, and the overall finish and polish are executed to a high standard to present clean lines and refined reflectivity.

Security of the gemstone setting is a primary design consideration and a key attribute of this piece from The Natural Sapphire Company, crafted to provide peace of mind in daily wear. The center sapphire is held by substantial prongs that are integrated into a reinforced white gold head, and the halo diamonds are captured with secure claws and shared settings that reduce movement while preserving light performance. The crown and gallery construction include internal support under the center stone to prevent undue stress on the prongs, and the junction between the head and the shank is reinforced to resist lateral forces. All settings are inspected during finishing to ensure prongs are appropriately formed and seats are clean and correctly sized, and the combination of 18K alloys and professional setting technique yields a durable mounting that minimizes the risk of stone displacement. For ongoing assurance, The Natural Sapphire Company provides guidance on routine inspection and gentle maintenance, and our craftsmen are available to perform professional servicing if required, ensuring that the stone remains secure and the ring retains its integrity over time.
