0.87 Ct. Bluish Grey Sapphire from Montana

This transparent 0.87 carat cushion shape bluish grey sapphire measures 5.12 x 5.06 x 3.65 mm, and presents a refined balance between size and presence, suitable for both classic and contemporary settings. The gem is cut as a mixed brilliant, combining the step facets of a traditional cushion profile with a brilliant pavilion that maximizes return of light, and the result is a jewel with lively scintillation and even face up color. Clarity is graded as very slightly included at eye level, so inclusions are minor and do not detract from overall transparency or brilliance, making the stone attractive to an educated buyer who values both natural character and visual performance. Color is medium intense bluish grey, a desirable and nuanced hue that reads as sophisticated and versatile, pairing well with platinum or white gold. The polish is excellent, indicating precise facet finishing that enhances luster and minimizes surface disruption, and the stone has been heat treated, a common and stable enhancement in sapphires that improves color saturation while preserving natural origin characteristics. Origin is Montana, which is prized for producing sapphires with distinctive, often subtle, and elegant color profiles, and provenance from this region adds contextual interest and market desirability for collectors and connoisseurs. At The Natural Sapphire Company we document each piece carefully, and this sapphire is presented with full disclosure of treatment and origin to support informed purchasing decisions.

The mixed brilliant cut is central to how this sapphire interacts with light, the pavilion’s brilliant facet architecture directs light back through the crown, creating internal reflection and scintillation that counterbalances the stone’s medium intense color, ensuring both color depth and lively fire. The cushion outline with softened corners increases the apparent size face up, and the combination of step crown facets and brilliant pavilion creates flashes of light that change with movement, enhancing visual dynamism without compromising the gem’s elegant, subdued bluish grey tone. For the discerning buyer focused on gem quality metrics, the very slightly included clarity grade means the stone exhibits natural inclusions typical of fine Montana sapphires, while excellent polish and precise facet symmetry indicate superior lapidary work that elevates optical performance. Collectors and those seeking a refined center stone will appreciate how cut, clarity, color, and finish converge in this 0.87 carat cushion sapphire, and The Natural Sapphire Company provides transparent documentation and expertise to ensure this gem meets expectations for both beauty and investment potential.
