1.17 Ct. Bluish Green Sapphire from Tanzania

If you are searching for a single stone that completes a thoughtful collection or becomes the centerpiece of a meaningful engagement ring, this oval bluish green sapphire answers that need with clarity and quiet confidence. This transparent 1.17 carat sapphire, expertly faceted in an oval shape with a mixed brilliant cut, measures 6.96 by 5.81 by 3.52 mm, and it presents an intense color intensity that immediately captures the eye. Evaluated at eye level the clarity is described as very slightly included, which means the gem reads as clean to the naked eye while retaining natural character that collectors prize. The polish is excellent, so the light performance and scintillation are impressive, and because this sapphire has undergone no enhancement, you are acquiring an authentic, natural gemstone in its original state. At The Natural Sapphire Company we understand that your search is not only for beauty, but also for integrity and lasting value, and this stone is ready to fulfill both desires.

For the conscious buyer who places ethics alongside aesthetics, the provenance and treatment of a gem matter as much as its color and cut. This sapphire originates from Tanzania, a region known for sapphires with beautiful and unusual tones, and the fact that it is unheated and unenhanced makes it rarer and more desirable for those who prefer minimal human intervention. At The Natural Sapphire Company we carefully source our material from partners whose practices we vet, and we emphasize traceability, fair dealings, and respect for the communities connected to these gemstones. Choosing an untreated Tanzanian sapphire means you are selecting a gem that not only offers a unique visual experience, but also aligns with a commitment to authenticity and mindful sourcing. For collectors and those buying an engagement stone, that combination of natural rarity and ethical provenance creates a meaningful purchase you will feel proud to wear and to pass on.

Visually this sapphire offers a compelling teal to bluish green palette that adapts beautifully to different lighting and settings, producing flashes of sea green and deeper blue when moved under light. The mixed brilliant cut enhances its brilliance while maintaining the oval silhouette that flatters a range of designs. At 6.96 by 5.81 mm the stone sits comfortably as a focal point for a single stone engagement ring or as the main gem in an artisan pendant. The very slightly included clarity grade contributes to the gem’s authenticity without detracting from its sparkle, and the excellent polish ensures each facet returns light with vitality. For an engagement ring, consider a classic four or six prong solitaire to showcase the stone’s color, or a delicate halo of small white diamonds to increase apparent size while preserving the sapphire’s unique hue. For collectors and those building a conscious jewelry wardrobe, this sapphire pairs beautifully with warm metals like yellow gold to emphasize the green tones, and with rose gold to create a vintage inspired warmth. Platinum will give a modern contrast that makes the bluish green appear cooler and more oceanic.

Sapphires are known for their durability and suitability for everyday wear, and this natural, untreated Tanzanian sapphire is no exception. With a hardness that resists scratches from daily activities and a polish that maintains its brilliance, this 1.17 carat oval sapphire is both practical and precious. Because it has not been subjected to heat or other enhancements, its long term stability is excellent, and its rarity among untreated sapphires can make it an enduring centerpiece for an ethical collection.
