1.67 Ct. Greenish Blue Sapphire from Tanzania

From deep within the mineral rich soils of Tanzania, this greenish blue sapphire began its long journey as a crystal formed under intense heat and pressure, slowly developing the clarity and color that make it so special. At 1.67 carats, with dimensions of 7.97 x 5.96 x 3.88 mm, it was selected for cutting because of its transparent body and pleasing medium color intensity. Skilled cutters shaped it into an elegant oval and applied a mixed brilliant cut to bring forward lively sparkle and depth, while an excellent polish gives each facet crisp reflections. Evaluated at eye level it is slightly included, a reminder of its natural origin and a feature that collectors and connoisseurs often cherish for the personality it lends. Importantly, this sapphire has no enhancement, a true, untreated treasure that carries the story of its geological birthplace to the wearer. At The Natural Sapphire Company we honor that story by ensuring every step from mine to market is documented and crafted with respect for provenance and quality.

Beyond its provenance and beauty this Tanzanian sapphire is exceptionally suited to daily wear, thanks to the inherent durability of corundum. Sapphires rank high on the Mohs scale of hardness, making them highly resistant to scratches from everyday surfaces, and the mixed brilliant cut and solid oval shape help distribute wear evenly across the stone. The medium depth and excellent polish combine to hide minor abrasions, while the slightly included clarity grade does not compromise structural integrity but rather gives the gem a unique character. For everyday settings we recommend secure prongs or a protective bezel to reduce the risk of impact to the girdle, and routine gentle cleaning will preserve its brilliance for years. Whether set as a centerpiece ring, a pendant close to the heart, or an heirloom piece that moves through generations, this 1.67 carat Tanzanian sapphire offers both the romance of a natural origin story and the practical toughness required for daily life, and our team at The Natural Sapphire Company is ready to guide you through mounting and care so this gem continues to tell its story for decades to come.
