1.60 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent 1.60 carat cushion shape blue sapphire measures 6.74 by 6.32 by 4.25 millimeters, giving it a depth ratio of approximately 65.1 percent, a proportion that balances face up presence with controlled light return. The gem is executed in a mixed brilliant cut, combining a brilliant facet arrangement on the crown with a carefully modified pavilion, yielding both intense scintillation and broad flashes of blue across the table. The cutter has retained a moderately sized table and well angled crown facets to maximize internal reflection, while the pavilion’s mixed facets create concentrated facets of light that enhance perceived depth without darkening the center. Clarity is graded very slightly included evaluated at eye level, indicating that inclusions are minor and do not interrupt the gem’s transparency or overall brilliance, and polish is graded excellent, reflecting meticulous lapidary finishing that produces sharp facet junctions and mirror like facet planes.

Color is a vivid blue with a saturated tone and lively chroma, characteristic of high quality Ceylon sapphires, and the stone displays an even color distribution when viewed face up, which is a direct result of both the material’s inherent zoning characteristics and the cutter’s orientation decisions. Origin Ceylon, Sri Lanka, is noted for producing sapphires with a vivid cornflower to royal blue palette, and this specimen shows the island’s signature vibrancy while maintaining full transparency, a combination that is highly sought after by connoisseurs. The sapphire has been heat treated, a stable and widely accepted enhancement that improves color saturation and clarity by reducing microscopic rutile silk and evening out tonal inconsistencies, this treatment is permanent under normal wear conditions and is disclosed to maintain full transparency of provenance and processing. From a gemological standpoint, the piece exhibits restrained pleochroic behavior due to the even oriented cutting, which translates to consistent color from multiple viewing angles, and its refractive interplay produces a balance between brilliance and fire that is optimized by the mixed brilliant facet schema.

Owning this sapphire is an investment in both beauty and craftsmanship, as it demonstrates technical excellence at every stage from rough selection through final polish, and represents a durable asset that carries both aesthetic and artisanal value. The precision of the pavilion angles and crown relationships indicate that the cutter prioritized light performance and durability, minimizing pavilion windows and maximizing return and scintillation, choices that retain allure when set in finger wear and that reduce the risk of light leakage that can diminish perceived color. At 1.60 carats in a cushion outline, the gem occupies a sweet spot where carat weight and face up size deliver visual impact without requiring an oversized setting, making it versatile for high quality solitaire or halo designs, while the stone’s excellent polish and minimal inclusions assure clean faceting detail under loupe and to the naked eye. The Natural Sapphire Company stands behind the piece with experiential sourcing, and a buyer acquires not only a superbly cut Ceylon sapphire but also the provenance and aftercare expertise necessary to preserve its appearance and value, with recommendations for secure bezel or four prong settings and routine professional cleaning to maintain brilliance over decades, thereby reinforcing the sapphire as a long term addition to a refined collection.
