1.49 Ct. Bluish Green Sapphire from Montana

This gem is a transparent 1.49 carat round sapphire, with precise dimensions of 6.86 by 6.86 by 4.48 millimeters, presenting a depth to diameter ratio of approximately 65 percent, a proportion that supports strong light return without excessive windowing. The cutter has executed a mixed brilliant cut, combining a classical brilliant crown with a modified brilliant pavilion geometry, which yields controlled flashes of white light and colored scintillation across small and larger movement ranges. Facet junctions appear well aligned, and the excellent polish enhances facet crispness, producing sharp contrast lines that delineate the star and kite facet pattern from the table through to the girdle. The table plane is balanced relative to the crown profile, supporting a pleasing face up spread for the given weight, and the girdle thickness has been managed to retain weight while preventing undue vulnerability at the bezel line. Clarity is graded as very slightly included, evaluated at eye level, which in practical terms means small internal features are visible under close inspection but do not materially interrupt the optical performance, allowing for strong brilliance and even light dispersion across the pavilion facets. The mixed brilliant faceting strategy is particularly effective for this material, as it captures and redistributes the available color while maintaining lively scintillation in daily wear scenarios.

The stone exhibits a bluish green hue at medium color intensity, a tonal balance that reads cool and subtly aquatic in daylight, and slightly greener under warmer indoor lighting, reflecting the complex interplay of trace elements that define Montana sapphires. The bluish green color is consistent with modest concentrations of iron combined with the typical chromium or titanium chemistry that produces blue to green zoning in corundum, and because this specimen is not heat treated or otherwise enhanced, the chromatic expression is entirely natural, stable, and collectible. No enhancement is reported, and that untreated status materially increases desirability among technically informed buyers, because untreated Montana sapphires are both less common and more valued for their natural state and predictable aging behavior. The medium intensity permits versatility in mounting choices, maintaining color presence in both white and warm metal settings, while the transparency and medium saturation allow light to penetrate and reflect across the internal facet architecture, creating a lively combination of brilliance and subtle color flashes rather than a flat or overly saturated appearance.

The provenance of this sapphire, originating from Montana, contributes distinct geological and historical value that sophisticated buyers recognize, and it aligns with a documented tradition of high quality, alluvial and hard rock corundum from the region. Montana sapphires are prized for their typically fresher, cooler color range and for the frequent occurrence of gems with good clarity and unique pastel to seafoam tones, characteristics that collectors and connoisseurs seek as a counterpoint to more heavily saturated, commonly treated material from other sources. The absence of enhancement, combined with Montana origin, allows for a transparent narrative of formation, extraction, and cutting, which enhances resale and heirloom potential. At The Natural Sapphire Company we document origin and treatment status through our internal protocols and through recommended independent gemological reporting when desired, because provenance and gemological clarity are central to the valuation of natural, untreated sapphires. For setting and wear considerations, the gem responds well to a well-engineered bezel or four prong setting that secures the slightly stout but well managed girdle, while allowing the crown facets to interact freely with incident light. The size and cut yield a comfortable presence on the finger, suitable as a solitaire centerpiece or as the focal element in a design that incorporates accent gemstones, and we can provide technical mounting drawings, light performance images, and certification guidance to ensure the finished piece meets both aesthetic and technical expectations.
