1.16 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent 1.16 carat cushion blue sapphire presents precise gemological measurements of 6.77 by 5.10 by 3.63 millimeters, yielding an overall depth percentage of approximately 61 percent, a proportion that optimizes face-up spread while preserving internal color saturation. The stone is fashioned in a mixed brilliant cut, combining a brilliant-cut crown with a faceted pavilion, a deliberate design choice that balances scintillation and color return in a sapphire of this origin. Facet junctions are clean and the polish is graded excellent, resulting in crisp light return and minimal surface detractors under loupe inspection. Clarity is assessed as slightly included at eye level, the inclusions are typical pinpoint and minor crystal features that do not compromise transparency or structural integrity, and they are positioned such that they have limited impact on the visual field when the gem is set. The well-executed girdle and symmetry allow the pavilion and crown angles to work together to reduce windowing and preserve an even face-up appearance.

Color is of primary importance in a collector-quality Ceylon sapphire, and this stone displays an intense blue, with vivid saturation and a medium to medium-deep tone that is characteristic of fine Sri Lankan material. The mixed cutting style enhances the stone’s color dynamics, producing lively scintillation without overly dispersing the blue hue, and the gem exhibits modest pleochroic behavior consistent with corundum, contributing subtle shifts between deeper and slightly lighter blue facets as the stone is tilted. Enhancement by heating has been applied, a stable and industry-standard treatment that improves color uniformity and clarity while maintaining natural origin and long-term stability. Origin is Ceylon, Sri Lanka, a provenance prized for producing sapphires with lively, pure blue tones and attractive optical properties. For the discerning collector seeking a compact, technically refined example of Ceylon sapphire, this 1.16 carat cushion combines precision cutting, excellent polish, intense color, and transparent character to serve as a sophisticated addition to a high-end gemstone collection, and it is offered by The Natural Sapphire Company with full disclosure of treatment and origin.
