This 1.40 carat, round shape, greenish blue sapphire measures 6.73 by 6.55 by 4.30 mm, and presents a transparent body with an intense color intensity and an excellent polish. The stone has been cut to a mixed brilliant profile to balance pavilion depth and crown dispersion, and the result is an engaging play of light without sacrificing weight retention. Clarity is graded very slightly included, evaluated at eye level, which means inclusions are minimal and do not detract from the gem's overall appearance when set. This sapphire has no enhancement, and its natural state is evident in the even saturation and the way color transitions across the table. Origin is Montana, a provenance that contributes to a distinct mineral character often appreciated by connoisseurs and makers of fine jewelry.
The journey of this sapphire from mine to market was deliberate and traceable, beginning with selective extraction in Montana where careful removal preserved the crystal form. From there the rough was examined by experienced lapidaries who considered crystal orientation and the relationship between weight and optical performance. The decision to execute a mixed brilliant cut was based on the rough geometry, with the objective of achieving intense color and optimal light return, followed by successive stages of preforming, faceting, and meticulous polishing to reach the excellent polish observed. Each stage included inspection under controlled light and loupe magnification, and the clarity evaluation was performed at eye level by a trained grader, confirming the very slightly included grade. No chemical or heat treatments were applied, and documentation of the no enhancement status accompanies the gemstone. The Natural Sapphire Company maintains provenance records and quality controls throughout this process, ensuring that the sapphire offered to clients reflects its documented origin and gemological attributes. In the market phase the sapphire is presented with precise specifications for informed selection, and its dimensions, weight, cut profile, clarity grade, color description, polish grade, enhancement status, and origin are recorded to assist designers and buyers in making a technically informed decision. The result is a single, natural gemstone that combines Montana character, uncompromised surface finish, and an intense greenish blue color, suitable for a range of fine jewelry purposes where natural, untreated material is a priority.
