0.38 Ct. Blue Sapphire from Ceylon (Sri Lanka)

At The Natural Sapphire Company we are pleased to present a transparent 0.38 carat round blue sapphire, dimensions 4.17 x 4.16 x 2.79 millimeters, fashioned in a mixed brilliant cut to balance scintillation and depth of color. This gem is graded as very slightly included when evaluated at eye level, with a medium color intensity and an excellent polish. The stone has been heat treated, a widely accepted enhancement that stabilizes and enriches the blue hue while preserving the crystal structure, and its documented origin is Ceylon Sri Lanka. For an educated buyer, the combination of Ceylon provenance, meticulous cutting proportions, and an eye level clarity grading communicates a gem that is natural, durable, and visually appealing in everyday jewelry. The mixed brilliant cut yields lively facet contrast, and the excellent polish maximizes light return, so the gem presents a bright face up appearance appropriate for fine rings or delicate pendants.

What gives this particular sapphire its unmistakable signature are the internal features that testify to its natural formation and make it distinct from laboratory grown or heavily treated material. Under magnification the stone shows a fine, evenly distributed silk and a scattering of minute crystal inclusions, arranged in subtle linear and cloudlike groupings that create a soft velvety texture when viewed face up. These inclusions act as an internal fingerprint, producing delicate depth and zonal color variation that enhances the perception of blue rather than flattening it. The inclusions are small enough to maintain strong brilliance, yet they add character and are a desirable attribute to collectors who value natural identification features. The very slightly included clarity grade means that these features are not distracting to the naked eye, but they are informative to the connoisseur and to gemologists verifying origin. Mounted in a well designed setting, this Ceylon sapphire will read as a cool, elegant blue with a distinct internal personality that speaks to its natural history, its stable heat treatment, and the careful cutting and polishing standards upheld by The Natural Sapphire Company.
