0.62 Ct. Bluish Green Sapphire from Montana

The Natural Sapphire Company is pleased to present a gem that speaks to the long arc of history while remaining utterly wearable in the present day. This is a transparent 0.62 carat, round shape bluish green sapphire, measured at 5.20 x 5.20 x 3.31 mm, cut as a mixed brilliant and finished with excellent polish. Its color is described as intense, a shade that recalls the deep waters and cool skies that have inspired jewelers and monarchs for millennia. Sapphires have been prized since antiquity for their association with wisdom, protection, and fidelity, and this Montana stone brings that lineage into a modern setting. Heat treated to enhance stability and color uniformity, and evaluated with a clarity grade of very very slightly included evaluated at eye level, this sapphire combines the patina of ancient tradition with the precision of contemporary lapidary art.

Montana has long been celebrated among connoisseurs as a source of sapphires with a distinct character, and this stone embodies that unique terroir. The bluish green hue is at once cool and complex, a color that shifts depending on viewing angle and environment, a trait that collectors and designers find irresistible. The round shape is a timeless choice that nods to classical proportions, while the mixed brilliant cut introduces a modern facet scheme that intensifies sparkle and depth. With an excellent polish, each facet edge is crisp, allowing light to enter and return with clarity, producing the lively play of light and contrast that gives life to the stone. The clarity of very very slightly included evaluated at eye level means the gem appears clean to the naked eye, preserving purity of field and allowing the saturated color to dominate the visual experience.

How this sapphire performs under different lighting conditions is central to its charm. In bright daylight, whether direct sun or clear northern light, the intense bluish green reads as a vivid, cool tone, with brilliant white flashes from the mixed brilliant facets that create scintillation across the table and crown. Daylight highlights the transparency and the gem will show crisp, lively reflections, while subtle secondary tones may emerge around the girdle and pavilion. Under incandescent or warm LED light, expect the color to take on a slightly greener or teal leaning, the warmth of the environment drawing out the green component and deepening the overall impression, while the excellent polish ensures that facets glow with soft, warm flashes rather than dulling. In cool fluorescent light, the sapphire will often present a stronger blue aspect, the cooler color temperature sharpening contrast and increasing the perceived saturation. In candlelight and other low light settings, the mixed brilliant cut ensures pleasing sparkle and movement, as the larger pavilion facets reflect warmer glints and the small crown facets deliver flashing pinpoints of light, giving the stone a romantic, mysterious presence that is perfect for evening wear. Movement and changing angles will reveal pockets of darker tone and lively specks of light, a structural choreography that has fascinated jewelry lovers for centuries.

This sapphire is ideal for an heirloom engagement ring, a pendant that sits close to the heart, or a custom design that highlights its round form and nuanced coloration. The mixed brilliant cut adapts beautifully to a variety of settings, including classic prong mounts that maximize light entry, bezel settings that emphasize the gem as a single, timeless focal point, or halo designs that use smaller accent stones to increase perceived size and enhance overall brilliance. Because the stone is heat treated, it has been stabilized in color, a common and accepted practice within the trade that preserves the natural beauty while improving consistency. The provenance of Montana imparts additional narrative value, connecting the wearer to the rugged landscapes where these crystals have been mined for generations. At The Natural Sapphire Company we understand the importance of legacy and craftsmanship, and we are available to advise on metal choices and setting styles that will complement the intense bluish green tone, preserve the excellent polish, and showcase the very very slightly included clarity so that the gem reads as clean and luminous in every lighting condition.
