1.97 Ct. Blue Sapphire from Tanzania

One extraordinary, transparent blue sapphire of 1.97 carat awaits the discerning collector who understands the rarity of truly untouched stones. This oval shape gem measures 8.74 x 6.04 x 4.12 mm, and carries a mixed brilliant cut that balances scintillation with depth. Its clarity is graded very slightly included evaluated at eye level, an affirmation that the gem appears clean and lively to the unaided eye while retaining natural character under magnification. The color presents as medium intense blue, a hue that reads vivid under natural light and adapts beautifully to both warm and cool metal tones. The polish has been graded excellent, allowing every facet to reflect light with crisp brightness, and importantly, this sapphire has no enhancement, a feature that heightens its rarity and investment value. Sourced from Tanzania, this sapphire is a single, unmistakable treasure from a respected origin, and it is offered exclusively through The Natural Sapphire Company.

The personality of this Tanzanian blue sapphire is eloquent yet restrained, delivering an impression of refined exclusivity rather than flash. Its mixed brilliant cut captures a generous spread of light across the oval table, generating lively flashes without sacrificing the stone's velvety blue saturation. Close inspection reveals only very slight natural inclusions, which serve as a fingerprint of authenticity and a reminder that this is a natural, untreated formation shaped by time and geology. The medium intense color intensity is particularly versatile, translating as a cool cornflower blue in morning light, and as a deeper, more regal tone under evening illumination. Because it is untreated, this sapphire will age gracefully, allowing future owners to pass forward a gem whose history and integrity are intact.

This sapphire invites a wide spectrum of bespoke settings, each design emphasizing a different facet of its uncommon charm. For a statement that places the gem at the center of attention, consider a classic solitaire ring with four or six prongs, or a minimal bezel that offers a modern, architectural silhouette while protecting the girdle. A halo of delicate diamonds will amplify brightness and impart the sensation of a larger presence on the finger, while a split shank or cathedral mounting can introduce elegance and stability for everyday wear. For collectors seeking drama, a three stone design with tapered baguette diamonds or pear shaped side stones will offer balanced visual momentum, drawing the eye to the sapphire as the principal actor. East west settings and bezel pendants convert the stone into distinctive, wearable art, ideal for layered necklaces or solitary statement pieces. Matched pairs of similar hue sapphires can be fashioned into drop earrings or studs, and custom cufflinks or signet adaptations present rare opportunities to wear this gem in non traditional formats. The gem pairs beautifully with platinum, which will emphasize its cool blue character, with 18 karat white gold for a refined, economical alternative, or with 18 karat yellow gold or rose gold for a warmer, more vintage inspired aesthetic. Design themes can range from minimalist modern, to vintage inspired filigree, to bold cocktail expressions, and every choice will speak to a different facet of exclusivity.
