1.80 Ct. Bluish Green Sapphire from Montana

This rare 1.80 carat cushion shape bluish green sapphire measures 7.72 x 6.55 x 4.68 mm, and was carefully fashioned with a mixed brilliant cut to maximize return of light and depth of color. Transparent and of intense color intensity, its hue sits between a deep teal and a cool sea green that shifts subtly as it turns under light. The gem is graded very slightly included at eye level, has an excellent polish, and has been heat treated to enhance its natural tone while preserving its distinctive character. Mined in Montana, this sapphire carries a provenance that is sought after by collectors and connoisseurs, and is offered by The Natural Sapphire Company as a singular example of North American sapphire beauty, available in incredibly limited quantity to those who value authenticity and rarity.

What sets this stone apart is the unmistakable signature created by its internal inclusions, a fingerprint that only nature could compose. Fine silk like needles thread through the pavilion and crown, catching light as soft shimmering veins, while tiny crystal pockets refract pinpoints of brightness that animate the gem from within. Gentle growth zoning and faint healed feathers lend a layered translucence that gives the bluish green field breadth and an almost three dimensional glow. These features are not blemishes, they are the atelier marks of time and pressure, proof of the sapphires natural genesis in Montana. When set, the mixed brilliant facets and excellent polish work in concert with these inclusions to produce flashes of petrol blue and green, a private spectacle that reveals itself differently depending on angle and light. For the discerning buyer seeking something beyond mass produced perfection, this sapphire is a bespoke treasure, a single, finite opportunity to own a gem whose personality is its provenance. The Natural Sapphire Company offers this gem to an exclusive circle of collectors and clients, and we will assist in creating a custom setting that honors its rare signature, ensuring it becomes a heirloom that is unmistakably yours.
