1.38 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 1.38 carat cushion shape blue sapphire measures 7.25 x 5.93 x 3.52 mm and is faceted in a mixed brilliant cut to balance scintillation and depth of tone, presented by The Natural Sapphire Company. The gem is transparent, with an intense color intensity and an excellent polish that allows light to enter and return with clarity and vivacity. The stone is untreated, with no enhancement, and originates from Ceylon Sri Lanka, a region celebrated for its cornflower and violet blue sapphires. The proportions and finish of this piece emphasize even color distribution across the crown, while the mixed brilliant facet arrangement creates lively internal reflections that complement the sapphire core color.

The inclusion suite within this sapphire gives it a distinct and unmistakable signature. Fine, silk like rutile needles are present in delicate intersecting arrays, producing a soft internal veil that gently moderates reflected light and contributes a subtle velvety character to the blue. Scattered pinpoint crystals and minute mineral crystals act as tiny reflective engines, catching light at different angles and creating an animated play of pinpoint sparkle when the stone is moved. There are also faint growth zoning lines that trace the crystal habit, visible under magnification, and occasional tiny negative crystals that appear as small, glassy cavities. Together these natural features form a complex internal landscape, one that reads as a fingerprint for the material and imparts depth and life to the overall appearance rather than detracting from clarity.

Although the sapphire is graded very slightly included when evaluated at eye level, the inclusions are restrained and do not diminish the gem s transparency or brilliance to the naked eye. The mixed brilliant cut and the excellent polish work in concert with the internal features to maximize light return while allowing the signature inclusions to be appreciated under close inspection. From a durability standpoint, the inclusions observed are typical of natural sapphires and do not present any known stability concerns with normal wear. For jewelry design, settings that display the table and crown will best showcase both the intense color and the subtle internal silk, and prong settings provide a classic presentation while bezel settings offer additional protection if the design calls for it.

The combination of intense Ceylon blue, transparent body, and a distinctive inclusion pattern makes this 1.38 carat cushion sapphire a clear example of a natural stone with character and provenance. The inclusion suite is not a flaw in the conventional sense, but rather an identifying feature that documents the gem s natural formation and contributes to its aesthetic complexity. The Natural Sapphire Company provides full disclosure on origin, treatment status, and the gem s measured attributes, and documentation is available upon request for collectors and designers who require certification. This sapphire is therefore presented as an untreated, well cut, and well polished example whose internal signature enhances its individuality and enduring appeal.
