4.05 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent 4.05 carat cushion shape blue sapphire measures 10.06 by 7.61 by 5.61 millimeters, producing an overall depth of approximately 63.5 percent, a dimension that balances face up presence with controlled pavilion volume for robust light return. The cutting style is faceted, executed in a mixed brilliant cut that combines a standard crown with a faceted pavilion to enhance scintillation and deliver a lively interplay between flashes and broad color, the mixed facets channeling light through the table for intense face up saturation. Clarity is graded included, evaluated at eye level, with natural internal characteristics that add character without compromising brilliance, the excellent polish ensuring crisp facet junctions and minimal surface disturbance, and the enhancement noted as heat treated, a standard and stable procedure to refine color and clarity. Origin Ceylon, Sri Lanka, a provenance known for vibrant blue tones, is evident in the vivid color intensity of this stone, a vivid blue that sits between pure blue and slightly violet leaning blue typical of high quality Ceylon material.

As a gift this sapphire presents a compelling technical and emotional proposition, its 4.05 carat weight and well controlled proportions making it a commanding solitaire or an elegant center for a halo or three stone mounting, the cushion outline offering both vintage appeal and contemporary versatility. The vivid color intensity combined with mixed brilliant faceting creates a focal point that reads as deep and luminous at arm length, while the eye level clarity and excellent polish ensure sparkle under direct and diffuse lighting alike. Sourced and selected with care by The Natural Sapphire Company, this gem is ready to be set into a bespoke commission or presented as a standalone heirloom, a striking gift that conveys thoughtful consideration through measurable gemological attributes, and a memorable balance of color, cut, and presence that will resonate with someone special.
