Accent Stones Purplish Blue Sapphire Ring 1.86 Ct., 18K Yellow Gold

This ring centers a transparent 1.86 carat oval purplish blue sapphire from Ceylon, with dimensions of 8.35 x 6.70 x 4.45 mm and a mixed brilliant cut. The stone displays vivid color saturation and an excellent polish, and it is heat treated to enhance its natural tone. The sapphire was evaluated as very slightly included at eye level, allowing strong light transmission through the pavilion and crown. The mixed brilliant cut combines a brilliant style crown with a precisely faceted pavilion, and the calculated depth of approximately 59 percent supports efficient light return. Facet geometry and angles have been designed to capture incoming light across the elongated oval surface, disperse it across the crown, and redirect it back through the table to maximize scintillation and perceived brilliance. The elongated outline of the oval provides a larger apparent surface area, and the mixed pavilion faceting reduces light leakage common to less refined cuts. These proportions and the careful facet junctions minimize the prevalence of the bow tie effect, producing a more even distribution of light and color across the table, while the excellent polish ensures unobstructed reflections from each facet edge.

Complementary white round natural diamonds totaling approximately 0.12 carats, clarity Very Slightly Included VS1, VS2 and color grade F, are set on the shoulders to enhance center stone brilliance through targeted contrast and reflective reinforcement. The diamonds are positioned to catch and return side light into the sapphire, amplifying scintillation and adding measured fire without competing with the sapphire s hue. The mounting is fully executed in 18K yellow gold with a four prong head elevation that allows ample light to enter the pavilion while maintaining secure setting geometry. The warm gold tone subtly enhances the purplish blue saturation of the Ceylon sapphire and provides a classic, enduring framework for the optical performance of the stones. The Natural Sapphire Company presents this ring with documentation of origin and treatment, and the construction and finishing reflect a focus on optical optimization, material quality, and durable craftsmanship.
