0.47 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This specimen is a transparent round shape blue sapphire weighing 0.47 carats, with precise dimensions of 4.68 by 4.69 by 2.91 millimeters. The cutter chose a faceted mixed brilliant geometry to balance optical performance and weight retention, combining a brilliant style crown with a modified pavilion. The table is proportioned to maximize internal reflection without sacrificing face up spread, and the overall proportions yield a depth of approximately 62.1 percent, a range that promotes lively return of light while preserving saturation. Facet junctions display consistent symmetry across the crown and pavilion, producing a controlled pattern of light and dark areas that contributes to scintillation under point lighting, and the girdle thickness is uniform to facilitate secure bezel or prong setting without material removal that would reduce carat weight.

Color is the defining attribute of this sapphire, with an intense color intensity that reads as a rich, bold blue, a tone and saturation that work together to convey personal power and distinction. The hue is a pure to slightly violet biased blue, with saturation concentrated toward the core that yields a velvety center when viewed at normal viewing distance, and lively sapphire brightness toward the facets that catch the light. The mixed brilliant cut was selected deliberately to enhance this color performance, the brilliant crown facets breaking light into strong flashes, while the modified pavilion concentrates color back into the table area, giving the stone a deep, authoritative presence on the finger. Origin is certified as Ceylon Sri Lanka, a source noted for producing blue sapphires with clarity and lively cornflower to deep blue tones, and the provenance from Ceylon reinforces the classical aesthetic and market desirability of this gem, as described in The Natural Sapphire Company records.

Clarity is graded as very very slightly included evaluated at eye level, indicating that inclusions are minute, sparse, and do not interfere with transparency or brilliance in typical viewing conditions. Under magnification these inclusions provide natural fingerprinting characteristics that are useful for identification and confirmation of natural origin, without detracting from the gem's overall visual performance. The polish is rated excellent, the surfaces are smooth with clean facet planes, and facet edges are sharp enough to delineate light return without over polishing that would soften contrast. The cutting craft shows attention to pavilion angle control, crown height uniformity, and precision of the culet alignment, which together minimize light leakage and improve overall brightness. Enhancement is heat treated, a stable and industry standard process that improves tone and saturation while maintaining durable crystal structure, and the treatment history is disclosed fully in our documentation to inform long term care and valuation.

From a mounting and design perspective this sapphire is well suited to a variety of settings that emphasize its intense blue and compact proportions. Its round shape and mixed brilliant architecture make it an excellent candidate for a classic solitaire setting where the clean lines and controlled depth permit efficient prong placement, and it also performs reliably as a center accent in three stone or halo compositions where its color can anchor a larger design. On a finger scale the stone occupies a discreet yet impactful visual footprint, demonstrating strong presence relative to its 0.47 carat weight, as seen in client images provided for scale. The Natural Sapphire Company stands behind the gem with full disclosure of origin, enhancement, and precise measurements, and our gemological team can provide additional documentation, matching services, and mounting recommendations tailored to the desired aesthetic and durability requirements. For buyers seeking a sapphire with technical excellence in cutting, confirmed Ceylon provenance, intense color, and the symbolic resonance of a rich bold blue as a statement of personal power and distinction, this sapphire represents a carefully considered option.
