Three Stone Bluish Grey Sapphire Ring 7.83 Ct., 18K White Gold

This ring from The Natural Sapphire Company centers on a 7.83 carat round bluish grey sapphire measuring 11.89 by 10.97 by 5.35 millimeters, cut as a double cabochon to maximize asterism and surface luster, the dome height and pavilion curvature are calibrated to create a crisp six ray star under direct light, the average diameter to depth ratio of approximately 47 percent is optimized for light return in translucent corundum, clarity is graded eye clean at normal viewing distance so the stone presents an unbroken field for the star, medium color saturation preserves a cool, silvery blue note typical of fine Ceylon material, polish is excellent which sharpens the star line and enhances reflected brilliance across the dome, provenance is central to the gem character because Ceylon sapphires are known for their fine silk inclusions and velvety tone which produce strong, centered asterism and a soft, cloud like body color that contrasts with highly saturated sapphires from other locales, the Sri Lankan origin therefore not only informs the visual character but also the historical and gemological desirability of the piece.

Flanking the central sapphire are two white round shaped lab grown diamonds totaling approximately 1.00 carats, each stone cut to ideal round brilliant proportions to deliver scintillation and contrast against the smooth cabochon surface, the color grade of F minimizes any warm contrast against the bluish grey sapphire while the clarity grades of VS1 and VS2 ensure clean facets that contribute bright, white return, the diamonds are matched for size and optical performance to maintain symmetry, their placement and relative weight at about 0.50 carats each balance the mass of the central stone and emphasize the star without overpowering the gentler tone of the sapphire.

The mounting is executed in platinum 950 with precision bezel settings that fully secure the cabochon and cradle the round diamonds in low profile cups, platinum 950 provides the density and tensile strength required for a secure bezel that protects the sapphire dome from knocks while enabling a high shine finish, hand finishing on the bezel lip and internal gallery polishes the metal to mirror like quality which complements the sapphire polish, construction details such as exact bezel wall thickness and internal seat geometry are calibrated to seat the double cabochon without stress, the result is a technically considered ring that celebrates Ceylon origin, stone cutting, and atelier level craftsmanship for the discerning buyer.
