1.04 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent 1.04 carat blue sapphire presents an emerald cut with exact dimensions of 6.35 x 4.68 x 3.32 mm, a profile that emphasizes proportion and optical clarity. The stone is a step cut, characterized by broad parallel facets on the crown and pavilion, and a relatively large rectangular table that produces controlled light return and a subtle, mirror like flash rather than overt scintillation. The clarity is graded as very slightly included, evaluated at eye level, and these inclusions are minimal and strategically positioned so as not to interrupt the stone s face up window. Color is described as intense, with saturated Ceylon blue tones that remain vivid across the table and through the pavilion, a quality helped by the cut which maximizes color depth while preserving weight. The finish is excellent, the polish delivering clean facet junctions and smooth facet planes, and symmetry that maintains the classic emerald cut lineation. The sapphire has been heat treated, a conventional and stable enhancement in sapphires from Sri Lanka, applied to improve chroma and clarity without compromising the gem s durability. The proportions yield an effective depth, approximately sixty percent relative to the mean of length and width, a balance engineered to optimize both light performance and face up presence in mounted jewelry.

When compared to historically famous sapphires, this stone offers a distinct and complementary profile. It shares origin and certain color characteristics with large Ceylon examples such as the Logan Sapphire, known for its clean crystal transparency and saturated blue, yet differs by virtue of its emerald cut and focused size. Where museum pieces like the Logan or the Star of India capture attention through scale and dramatic presence, this sapphire provides a more intimate expression of Ceylon color, ideal for precision set pieces where clarity and step cut geometry are paramount. By contrast with Kashmir sapphires, which are renowned for their velvety cornflower blue and silk like diffusion, this gem shows a cleaner, more crystalline transmission of color that reads as intense and lively rather than soft. The emerald cut also places it in a lineage with historically significant step cut stones, those prized by connoisseurs for the honest revelation of color and clarity, similar in spirit to certain famous blue spinels and sapphires that have been fashioned into elegant step cut gems for royal jewelry. The result is a sapphire that carries a classical, almost architectural aesthetic, offering a different kind of rarity than large museum pieces, a rarity defined by optical purity, precise geometry, and wearable scale.

From the perspective of The Natural Sapphire Company, this sapphire represents a deliberate choice in cutting and finishing to achieve maximum market value per carat while honoring the material s inherent qualities. The cutter retained weight to achieve 1.04 carats rather than over faceting to chase brilliance, a decision that preserves color saturation and maintains the clean, open table that emerald cut admirers seek. For setting recommendations, the emerald cut profile is well suited to both four prong and bezel styles, each highlighting different virtues, prongs to showcase the table and pavilion depth, bezel to protect the corners and emphasize the clean rectangular silhouette. Platinum or eighteen carat white gold settings will enhance the cool, intense blue, while warm yellow or rose gold settings will create a classical contrast that can warm the perceived tone. For bespoke commissions, consideration of a cathedral gallery and low profile mounting will allow the stone s step facets to interact with ambient light, producing flashes that complement, rather than compete with, the inherent color. Our team provides full disclosure on heat treatment and provenance, and we are prepared to supply detailed imaging and facet level observations on request, including a loupe view description and a report that documents the origin as Ceylon Sri Lanka. For collectors who value technical transparency and refined cutting, this emerald cut blue sapphire is a precisely executed example of Ceylon material, offering the clarity and intense color that experienced buyers seek, presented with the craftsmanship standards and provenance documentation upheld by The Natural Sapphire Company.
