0.86 Ct. Bluish Green Sapphire from Montana

This transparent 0.86 carat asscher - octagon shape bluish green sapphire from Montana presents a compact yet highly wearable size at 5.62 x 5.27 x 3.50 mm, an ideal proportion for both classic and modern jewellery. The asscher cut, an octagonal step cut with broad, concentric facets, was chosen to emphasize the stone’s medium color intensity and to produce a sophisticated play of light rather than brilliant sparkle. The step facets create a hall-of-mirrors effect that accentuates the sapphire’s bluish green hue while preserving strong face-up color, which is prized by connoisseurs. Clarity is graded as very slightly included, evaluated at eye level, meaning the gem is essentially eye-clean with only minor internal characteristics that do not detract from its appearance or performance in most settings. An excellent polish further refines facet junctions and surface finish, improving luster and allowing the gem’s true color and depth to read clearly to the naked eye. This stone has been heat treated, a stable and widely accepted enhancement that improves color uniformity and optical properties without reducing durability, a factor experienced buyers understand and anticipate when assessing value.

Beyond the technical specifications, this sapphire’s bluish green tone carries notable rarity and stylistic versatility. Montana sapphires are well-regarded for their unique spectrum of blues and greens, often yielding hues that are distinct from typical heat-treated sapphires from other localities, and collectors appreciate provenance when it complements unusual coloration. The combination of an elegant asscher cut, medium color intensity, and eye-clean clarity at 0.86 carat makes this gem especially desirable to an educated buyer who values proportion, optical performance, and natural character. The rich, bold color as a symbol of personal power and distinction will translate beautifully into a pendant, ring, or bespoke piece where the octagonal geometry can be showcased. For secure mounting, settings that protect the step-cut corners and allow light to enter the pavilion will maximize the stone’s presence. At The Natural Sapphire Company we document each sapphire’s characteristics transparently and can advise on ideal setting styles and customization to ensure this Montana asscher sapphire performs as a wearable statement of refined taste and enduring value.
