1.13 Ct. Blue Sapphire from Tanzania

Sapphires have held a special place in human history for millennia, admired by kings, priests, and poets for their deep blue glow and apparent permanence, and this cushion shape blue sapphire carries that same sense of enduring legacy, its form echoing the soft, antique curves of gemstones set in heirloom jewels, its mixed brilliant cut giving a modern precision to a classic silhouette, the kind of gem that speaks to those who cherish continuity, ritual, and beauty that transcends passing trends. From the ancient lapis of Mesopotamia through medieval signet rings and royal regalia, blue sapphires have symbolized wisdom, fidelity, and protection, and they remain a favored choice for collectors who value lineage and story, those who want a piece that will feel at home in both a museum cabinet and an everyday life. This sapphire is not merely a stone, it is a continuation of that long tradition, a tangible link to the past that is refined by modern cutting and finishing to live beautifully in the present, and to be passed with pride into the future.

At the heart of this offering is one transparent 1.13 carat cushion shape blue sapphire, with precise dimensions of 6.13 by 4.82 by 4.14 millimeters, a compact and versatile size that adapts gracefully to both delicate rings and refined pendants, and a mixed brilliant cut that balances scintillation and depth to reveal a lively play of light across its facets. The clarity has been evaluated as very slightly included at eye level, a grade that affirms the gem’s natural character while maintaining exceptional visual purity, and the color intensity is vivid, the deep classic blue that connoisseurs seek when selecting a sapphire for an engagement piece or an elegant daytime jewel. The polish is excellent, allowing the gem to reflect light with crispness and to show the internal color zones and flashes that make each natural sapphire unique, and importantly this stone has no enhancement, a quality that preserves its original geological story and ensures that what you see is the sapphire as formed beneath the earth, not altered by heat or other treatments. This sapphire originates from Tanzania, a region known for producing stones with rich saturation and a pleasing depth of tone, and its provenance contributes to the gem’s distinctive character and desirability.

The Natural Sapphire Company has built its reputation on transparent and responsible sourcing, and this sapphire is presented with that same commitment, a choice for the conscious consumer who wishes to know both the natural and human story behind the jewel. We work directly with trusted partners and with mining communities to ensure fair purchasing practices and to support livelihoods, and our sourcing emphasizes traceability and respect for the land and the people who bring these stones to light. Choosing an unenhanced Tanzanian sapphire through The Natural Sapphire Company means selecting a gem whose beauty has not been manufactured, and it means aligning with a house that values long term relationships with miners and dealers, ethical labor practices, and environmentally mindful approaches to extraction and processing wherever possible. For collectors and buyers who place stewardship and integrity alongside aesthetic criteria, this sapphire offers a rare combination of natural authenticity and conscientious provenance, a jewel you can wear with pride and pass on with confidence.

This stone fits elegantly into a conscious collector’s repertoire, its 1.13 carat weight and cushion profile offering flexibility for a range of classic and contemporary settings, and its vivid blue and excellent polish making it an ideal centerpiece for a solitaire ring, a vintage inspired halo, a minimalist bezel pendant, or an understated pair of stud earrings when matched with a complementary partner gem. For a timeless look that honors the sapphire’s history, consider a warm gold setting that references old world jewelry, or a white metal setting in platinum for a more modern, architectural presentation that allows the color to read cooler and purer. The sapphire’s hardness as corundum means it is well suited to everyday wear, and its modest size is especially appealing to those who prefer refined understatement, or who are building a collection anchored by classic stones intended to serve as family heirlooms. For the conscious buyer, combining this unenhanced Tanzanian sapphire with ethically sourced accent diamonds or recycled metal settings can create a wholly responsible and beautiful object that holds meaning on multiple levels.

Caring for this sapphire is straightforward, and its natural state without enhancement simplifies stewardship while inviting thoughtful handling that will preserve its beauty for generations, clean the gem gently with warm water, a mild soap, and a soft brush, rinse thoroughly, and dry with a soft cloth, and for deeper cleaning or polishing consult a trusted jeweler and request professional care from jewelers experienced with natural, unheated sapphires. The Natural Sapphire Company stands behind the gem with full documentation of its attributes and origin, and we are pleased to offer bespoke design consultations to help you create a setting that reflects your values and aesthetic, whether you are selecting a first piece, adding to a curated collection, or designing an engagement jewel meant to embody lifelong commitment and ethical intent.
