0.81 Ct. Greyish Blue Sapphire from Montana

This transparent 0.81 carat round greyish blue sapphire measures 5.56 by 5.57 by 3.65 millimeters, presenting a compact profile with a depth percentage of approximately 65.6 percent, calculated from the measured dimensions. The stone is cut in a mixed brilliant style, combining a brilliant facet arrangement on the crown with a more controlled pavilion schematic, optimizing both scintillation and color concentration. The medium intense color intensity registers as a subtle greyish blue, a balance between cool blue saturation and a silvery grey veil that modulates the stone s optical response under varied lighting. Clarity is graded as slightly included when evaluated at eye level, with modest internal features that do not disrupt the overall transparency or light return, and in many orientations they function as pinpoint and feather accents that animate the gem rather than detract from it. The polish is excellent, the facet junctions are crisp, and the heat treatment applied to this Montana sapphire is a standard, stable enhancement that refines tone and improves clarity without compromising the integrity of the crystal structure. The origin of Montana imparts a distinct regional character to the color profile, lending an earthy coolness and a unique vintage tone that distinguishes it from classic blue sapphires.

Beyond the technical profile there is a romantic story embodied in this gem, a narrative rooted in its greyish blue hue and the gentle inclusions that punctuate its interior. Imagine a twilight under the wide Montana sky, the horizon slipping from daylight blue into a soft, steel grey, the exact chroma captured in this 0.81 carat round. The slightly included clarity reads like a whispered memory, tiny internal marks resembling distant stars reflected in a calm river, reminders that true beauty is lived and layered. For the client seeking a piece with both geological authenticity and emotional resonance, The Natural Sapphire Company offers this gem as a perfect candidate for a signature piece, particularly suited to settings that showcase its mixed brilliant optics, such as a low bezel to emphasize color, or a four prong mounting to maximize light entry and scintillation. The combination of measured proportions, medium intense color, competent clarity, excellent polish, and responsible heat treatment makes this Montana sapphire a technically interesting and evocative choice for bespoke jewelry, carrying both the precision of fine lapidary work and the soft romance of Big Sky evenings.
