0.82 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This is a transparent 0.82 carat cushion shape blue sapphire, precisely measured at 6.03 x 4.23 x 3.52 mm, with a mixed brilliant cut that balances table size and pavilion depth. The stone displays vivid color intensity and an excellent polish, clarity graded as very very slightly included at eye level, and a visual profile that reads clean and lively under both natural and controlled lighting. The sapphire is heat treated, a standard and stable enhancement, and its documented origin is Ceylon, Sri Lanka. The Natural Sapphire Company has recorded these specifications to ensure accurate representation and to support provenance documentation.

The journey of this sapphire began in Sri Lanka where the rough crystal was extracted from alluvial gravels and primary deposits by experienced miners using methods designed to preserve crystal integrity. The rough was evaluated at source for color zoning, crystal habit, and potential yield, then selected for faceting based on optical response. Controlled heat treatment was applied in a laboratory setting to enhance color saturation and clarity, following established practices that maintain the gem s stability. A skilled lapidary executed the cushion shape with a mixed brilliant facet scheme, optimizing light return while preserving weight and proportions, then completed an excellent polish that enhances the stone s cellar blue flashes and pavilion brilliance. Subsequent inspection assessed clarity at eye level, confirmed dimensions and weight, and produced imaging and documentation for inventory.

From the workshop the sapphire entered a secure supply chain managed by The Natural Sapphire Company, where it underwent final quality control, photographic documentation, and packaging for market presentation. Technical details accompany the gem including carat weight, measurements, cut description, clarity notation, color intensity, polish grade, enhancement disclosure, and origin statement. For practical use the dimensions and mixed brilliant cut suit a range of settings, most commonly solitaire and halo ring designs where the cushion outline and vivid color are showcased. Minor inclusions are consistent with the clarity grade and do not detract from the gem s appearance to the naked eye, however proper setting and periodic care are recommended to preserve the polish and color. Documentation is available upon request to support provenance and treatment disclosure.
