0.86 Ct. Greenish Blue Sapphire from Montana

One exceptional, transparent greenish blue sapphire weighing 0.86 carat invites a moment of measured admiration, a jewel that speaks softly yet persuasively of rarity and refinement. This oval shaped gem measures 5.86 by 5.07 by 3.74 millimeters and has been expertly fashioned with a mixed brilliant cut to balance scintillation with depth. Evaluated at eye level, the clarity is very slightly included, a testament to its natural origin and an assurance of luminous performance rather than distraction. The color intensity is described as intense, a vibrant blend of blue and green that shifts with movement and light, while an excellent polish ensures each facet meets the eye with crisp, mirror like finish. This sapphire has received heat treatment, a subtle enhancement commonly used to clarify and deepen color, and its provenance from Montana lends it a storied American pedigree that appeals to collectors and connoisseurs who prize traceable origin and character. Presented by The Natural Sapphire Company, this stone is both a statement and a promise, an object to be set into a creation that will carry its provenance and personality for generations.

The mixed brilliant cut of this oval sapphire creates a play between fiery sparkle and broad color zones, rendering it ideal for settings that celebrate both light and depth. In a solitaire ring the gem will take center stage, its oval silhouette elongating the finger and its intense hue made more vivid by a sleek platinum or white gold setting. A delicate halo of brilliant white diamonds will increase perceived size and add theatrical contrast, while a double halo or hidden halo can introduce subtle architecture without overwhelming the sapphire itself. For those who favor warmth and contrast, a bezel or prong setting in 18 karat yellow or rose gold will coax forward the green undertone, creating an almost vintage, heirloom energy. The stone’s proportions also make it perfect for an east west mount for a contemporary, understated twist, or for a cathedral or split shank design where the light can enter the pavilion freely and return as scintillation and brilliance.

Beyond the ring, this 0.86 carat oval sapphire can be transformed into an array of bespoke jewelry forms that reflect personal taste and lifestyle. As a pendant set within a fine halo or a minimalist bezel it will hang close to the heart and catch the light with every motion, a tasteful talisman for daily wear. As a pair of asymmetric study earrings, matched with small diamonds or paired with complementary sapphires, it can anchor a refined ear stack or a single stud for formal evenings. Men’s jewelry, including a signet or cufflinks, takes on understated luxury when a single Montana sapphire is set into a flat bezel or low profile mount, offering color and character without ostentation. For those who pursue more ornate styling, vintage inspired filigree, milgrain edges, and pavé shoulders will place the gem within the language of history, while modern tension settings and geometric galleries will carve out a very different, contemporary silhouette. The sapphire’s hardness, second only to diamond, ensures durability for everyday settings, and a bezel or low profile gallery will best protect the stone’s girdle for active wear.

At The Natural Sapphire Company we celebrate the possibility of transformation, and this Montana sapphire is a perfect canvas for a bespoke commission. Our design service offers CAD renderings, thoughtful metal selections, and options to pair the sapphire with responsibly sourced diamonds or colored gemstones for contrast and depth. Consider accents of champagne diamonds to whisper warmth, or a trio configuration with tapered baguettes to create an Art Deco statement. For those seeking personalization, hand engraving and hidden details such as message plates or signature stones can embed private meaning into the piece. We provide full disclosure of treatment and origin, and guide choices that enhance the stone’s intense color and excellent polish while respecting its natural character. Owning this sapphire is more than a purchase, it is an affirmation of cultivated taste, a choice to carry a rare American gem into the rituals of daily life and celebration.
