5.03 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

This C.Dunaigre certified Yellow sapphire from Ceylon is a transparent, intensely colored gemstone that combines measured proportions with clear documentation, presented by The Natural Sapphire Company. The stone weighs 5.03 carats, and its face dimensions measure 11.07 by 8.24 by 5.38 millimeters, delivering a substantial presence without compromising practicality for fine jewelry. The emerald cut shape emphasizes linear symmetry and controlled light return, and the overall presentation is defined by an intense, pure yellow hue with even saturation across the table. The origin from Sri Lanka contributes to the gemstone family attributes and to the expected interaction of color and light, and the certification by C.Dunaigre confirms the weight, dimensions, origin, treatment, and observed clarity characteristics. Heat treatment has been applied, which is an established enhancement method for yellow sapphires to stabilize and intensify color, and this treatment is disclosed and documented in the certification.

The emerald cut in this specimen is executed with a focus on proportion and facet placement, offering exceptional cut and brilliance that make the stone a natural centerpiece for any collection. The step cut planes create broad, luminous facets that emphasize color depth and clarity, while the precise symmetry and excellent polish allow for crisp reflections and a vivid, glasslike brilliance. Clarity is graded as very very slightly included, evaluated at eye level, indicating that inclusions are minimal and do not interfere with the gem's visual performance when set or worn. The combination of transparency and intense color intensity produces a lively face up that maintains saturation under varied lighting, and the broad facets of the emerald cut promote a refined interplay of light and shadow that accentuates the stone's clarity and color rather than masking them. The excellent polish contributes to surface brightness and to the perceptible quality of the finish, and the careful faceting preserves weight while optimizing table size and overall visual impact.

From a design and practical standpoint this sapphire is versatile for both classic and contemporary settings, and its substantial dimensions give it presence in solitaire, halo, or three stone compositions. In a solitaire setting the clean lines of the emerald cut read with architectural clarity, creating a modern but timeless silhouette. When paired with accent stones the even color distribution and high polish allow complementary gems to enhance the visual effect without competing with the primary color field. The stone responds well to open gallery settings that permit light to enter and leave through the pavilion, which supports the step cut light dynamics and maximizes perceived brilliance. The documented heat treatment is stable under normal wear conditions, and standard care recommendations apply, including avoiding prolonged exposure to harsh chemicals and undertaking professional inspections of settings at regular intervals to ensure the stone remains secure.

The combination of a 5.03 carat weight, measured dimensions of 11.07 by 8.24 by 5.38 millimeters, emerald cut geometry, intense yellow color, very very slightly included clarity at eye level, and excellent polish defines the gem as an exceptional example of a Ceylon yellow sapphire. For collectors and designers seeking a gemstone that functions as a visual focal point, while also meeting rigorous standards of documentation and lapidary execution, this sapphire represents a refined balance of color, clarity, and cut. The stone is presented ready for bespoke mounting, and detailed images and the certification accompany the gem to facilitate decision making and to confirm its attributes.
