10.99 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

This listing describes a GRS certified natural yellow sapphire from Ceylon Sri Lanka, presenting a weight of 10.99 carat, a radiant shape, and dimensions of 12.25 by 10.63 by 7.92 mm. The stone is transparent and untreated, with enhancement reported as none, preserving the gem in its natural state. Clarity is graded as very slightly included when evaluated at eye level, an assessment that indicates inclusions are minimal and do not detract from visual performance under normal viewing. Color intensity is recorded as intense, and the polish is graded as excellent. These precise laboratory details form the basis for the stone evaluation and support the gemstone identity and character affirmed by the GRS certification in the accompanying report.

The radiant cut is executed to emphasize brilliance, and the facet arrangement on this stone has been worked to maximize light return through a balanced crown and pavilion interplay. Facet junctions and symmetry are refined to promote lively scintillation and a uniform spread of light across the table, enabling strong contrast and return that accentuate the stone color. The cut proportions yield a broad face up area that showcases the saturated yellow, while depth proportions maintain internal reflection and flash. The excellent polish contributes to crisp facet edges and smooth planes, which together enable clean light play and enhance both sparkle and fire potential where present in yellow sapphires.

Visually the sapphire presents a vivid golden yellow that retains clarity and brightness across multiple viewing angles, making it well suited to function as a centerpiece in jewelry design. Its transparent body allows the intense hue to read clearly without appearing muddy or overly dark, preserving definition of the facet pattern. The moderate size and substantial carat weight provide presence while remaining adaptable to a range of settings, from a bold solitaire ring to a refined pendant or bespoke three stone composition. The provenance from Ceylon Sri Lanka contributes to the color character, with regional examples often noted for luminous, saturated tones and a pleasing balance between warmth and clarity.

For professionals and private collectors assessing suitability for a finished design, the 12.25 by 10.63 by 7.92 mm proportions support secure mounting and practical wear, and the durable corundum matrix assures everyday resilience with appropriate care. The very slightly included clarity grade indicates that inclusions will not unduly complicate setting or finishing, and the excellent polish helps minimize surface wear risk over time. The Natural Sapphire Company stands behind the certification and the factual presentation of this sapphire, and the accompanying GRS report documents origin, enhancement status, measurements, weight, and the clarity and color determinations that underpin its value and desirability. This yellow radiant sapphire combines natural origin, precise cutting, and notable brilliance to serve as a distinguished focal point in any fine jewelry collection.
