1.25 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This sapphire is a transparent, round shape blue sapphire weighing 1.25 carats, with precise dimensions of 6.79 by 6.76 by 3.86 millimeters. The cutting style is faceted, and the gem displays a mixed brilliant cut designed to balance scintillation and color saturation. At eye level the stone is graded eye clean, exhibiting no inclusions visible without magnification, and it has a vivid color intensity that presents as a deep, pure blue with lively internal reflections. The polish is excellent, producing crisp facet junctions and clean surface planes that maximize light return and visual depth. The stone has undergone controlled heat treatment, a standard and stable enhancement in the trade, and its documented origin is Ceylon, Sri Lanka, a region renowned for producing corundum with characteristic brightness and clarity. The Natural Sapphire Company is providing this sapphire with full disclosure of these attributes, so that its specifications and treatment are clear to anyone considering it.

The journey of this sapphire began in the alluvial gravels and primary deposits of Sri Lanka, where corundum forms in metamorphic host rocks under long periods of geological pressure and heat. In its rough state the material was identified and selected by experienced local miners for its promising color and clarity. Once extracted, the rough was sorted by size and quality, and then it was moved to a trusted cutting house where experienced lapidaries assessed the crystal orientation and internal structure to determine the most appropriate cutting plan. Quality control at the sourcing stage included visual inspection and documentation of origin, to preserve traceability. The local provenance contributes to the gem character, and sampling and testing confirmed the stone s natural corundum identity prior to any enhancement. Throughout this phase the focus was on retaining as much weight as practical while enhancing the stone s optical properties, so that color and brilliance could be balanced against carat weight.

At the cutting bench the sapphire was shaped into a round mixed brilliant arrangement, a choice made to optimize both the depth of color and the fire that is possible within a medium sized stone. The cutter employed a precise facet scheme on the crown and pavilion to encourage even light return and to avoid windows or dark areas, while maintaining an overall depth of 3.86 millimeters on an average diameter of approximately 6.78 millimeters, yielding a depth to diameter ratio in the range of 57 percent. This proportion helps the gem present as both lively and deeply colored when set. Facet polish was carried out to an exacting standard, and the final stone exhibits excellent symmetry and crisp facet junctions that contribute to its eye clean appearance. The heat treatment was applied in a controlled environment to enhance color saturation and clarity without compromising crystalline integrity. Heat treatment is widely practiced and, when properly performed, yields permanent improvements that are stable over time. The result is a sapphire that combines transparency, vivid blue color, and carefully engineered brilliance.

Upon completion of cutting and finishing the stone was reviewed and documented by our quality team, and then prepared for market presentation by The Natural Sapphire Company. The documentation accompanying the stone records the carat weight, dimensions, cut style, clarity grade at eye level, polish quality, enhancement method, and origin. The finished gem is suitable for a range of jewelry applications where a balance of color and proportion is desired, including solitaire ring settings, bezel mounts, or as a focal center in more elaborate designs. For care we recommend routine gentle cleaning with warm soapy water and a soft brush, avoidance of harsh chemicals, and professional inspection if it is set into fine jewelry. This sapphire s combination of documented origin, technical specifications, and careful workmanship makes it an enduring and verifiable gemstone choice. The Natural Sapphire Company stands by the accuracy of these details, and provides clear provenance and treatment disclosure so that the stone s lifecycle from mine to market can be understood with confidence.
