Pave Blue Sapphire Ring 4.50 Ct., Platinum 950

This heart shaped 4.50 carat blue sapphire is a fine example of Ceylon gemology, certified by C.Dunaigre as Vivid Blue, a designation that speaks to both hue purity and saturation. Measuring 9.60 by 10.33 by 6.04 millimeters, the stone displays a vivid color saturation that is prized by educated collectors, and it is evaluated as eye clean at normal viewing distance, providing visual purity without visible inclusions to the unaided eye. The mixed brilliant cut combines a faceting scheme that balances large table and crown facets with a precision pavilion, producing a lively play of light while preserving the depth of color characteristic of Sri Lankan sapphires. Excellent polish enhances facet contrast and sharpness, allowing clean facet junctions that contribute to crisp light return and a lively surface scintillation. The sapphire provenance from Ceylon adds to its desirability, Ceylon being renowned for producing sapphires with a luminous, velvety blue that reads both vivid and natural, attributes that collectors and connoisseurs recognize as rare and valuable.

The mounting further amplifies the gemological strengths of the center stone, the mixed brilliant heart shape set in 14 karat white gold to provide a cool, reflective backdrop that accentuates the blue saturation. Accent diamonds are channelled and set to frame the center gem, with white round natural diamonds weighing approximately 0.09 carat and graded Very Slightly Included in VS1 and VS2 ranges, color F, and additional white round natural diamonds weighing approximately 0.126 carats with clarity in the VS range and color F to G. These high quality accent stones increase perceived brilliance and add contrast without overpowering the sapphire, their near colorless tones preserving the sapphire blues true appearance. The cutting geometry of the mixed brilliant heart maximizes internal reflections, the crown facets directing light into the pavilion, and the pavilion angles engineered to return that light through the crown for optimal brilliance and fire, while the heart outline and symmetry ensure distributed light return across the entire table. At The Natural Sapphire Company this ring represents a thoughtful marriage of provenance, precise cutting, and complementary diamond accents, a piece designed for the buyer who values documented origin, clarity, and the optical performance of expert cutting.
