Halo Bluish Green Sapphire Ring 3.51 Ct., 18K Yellow Gold

The center gemstone is a 3.51 carat oval bluish green sapphire, measuring 9.83 x 7.43 x 5.40 mm, cut in a mixed brilliant style that is executed with careful precision. The mixed brilliant cut here integrates a brilliant facet arrangement on the crown with controlled step or modified pavilion facets, producing a balance between lively scintillation and stable color delivery. Facet junctions are sharply defined and consistently aligned, allowing even light return across the table and preventing disruptive flash zones. The pavilion planes are expertly proportioned to support depth and saturation, while the crown angles are calibrated to maximize dynamic dispersion and surface brilliance, resulting in an overall presentation that reads as intense and evenly saturated at a variety of viewing angles.

Clarity is graded eye clean, evaluated at eye level, and the sapphire displays an excellent polish, which enhances both transparency and the precision of the facet surfaces. Heat treatment has been applied to optimize hue and saturation, a common and stable enhancement that refines the stone without obscuring its natural character. Origin is Africa, and the gem’s mixed brilliant geometry helps to distribute the bluish green tone uniformly, minimizing visible zoning while emphasizing depth. The cutting quality is evident in the evenness of light return across the oval plane, and in the fine symmetry that maintains the gem’s proportions at 9.83 x 7.43 x 5.40 mm.

Surrounding the sapphire is a halo of white round natural diamonds totaling approximately 1.08 carats, selected for a color grade of F and clarity grades of VS1 and VS2, which complement the sapphire by providing bright, neutral contrast without introducing warmth. The diamonds are set in a refined halo arrangement in 18K yellow gold, with prong work that is both secure and unobtrusive, preserving the visual emphasis on the precise faceting of the center stone. The overall mounting is executed to align the optical axes of the center and accent stones, ensuring cohesive light performance. This ring, presented by The Natural Sapphire Company, is a study in faceting precision, where measured proportions, strict symmetry, and meticulous polish combine to showcase the sapphire’s color and clarity with clarity and restraint.
