4.03 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This is a singular opportunity to welcome into your collection a rare, transparent 4.03 carat cushion shape blue sapphire, a stone that stands apart for its size, color, and provenance, available through The Natural Sapphire Company. Measuring 10.80 x 8.49 x 4.70 mm, this gem has been masterfully faceted in a mixed brilliant cut that balances scintillation with depth, producing a face up presence that is both immediate and enduring. At eye level the clarity is graded very slightly included, a mark that confirms natural origin while preserving the gemological purity that serious collectors demand. The color intensity is vivid, the polish is excellent, and the subtle benefit of considered heat treatment has been applied and disclosed to enhance stability and vibrancy. Sourced from Ceylon Sri Lanka, this sapphire carries the legacy of one of the world most storied gem producing regions, a rarity that will distinguish any thoughtful collection, and that will signal to connoisseurs that you are selecting stones with provenance and purpose.

To hold this sapphire is to experience a depth of blue that changes with every angle and ambient light, a blue that can be described as regal, oceanic, and exceedingly alive. The cushion outline softens the power of the color, allowing it to sit elegantly on a finger or within a custom pendant, while the mixed brilliant faceting pattern sends flashes of brilliance across the table and along the crown facets. The dimensions offer comfortable wearability, and the 4.03 carat weight translates into a size that reads both significant and refined, ideal for a client who wants presence without ostentation. Under careful examination the inclusions reveal the stone natural character, adding to its story rather than detracting from its beauty, and the excellent polish ensures clean reflections and crisp facet junctions. This is the kind of sapphire that photographs superbly and performs even better in person, a jewel that invites lingering glances and repeated admiring comments.
