1.87 Ct. Blue Sapphire from Tanzania

This transparent 1.87 carat oval blue sapphire measures 8.44 x 6.38 x 3.84 mm and features a mixed brilliant cut that balances table brightness with well defined pavilion facets, producing a refined play of light. The stone displays a medium light color intensity, offering a delicate, clear blue tone that reads consistently across the crown and pavilion, and it has an excellent polish that enhances surface luster. Clarity is graded as very very slightly included when evaluated at eye level, indicating minimal internal characteristics that do not detract from visual appeal or light performance. This sapphire is untreated, with no enhancement, and its provenance is Tanzania, a source known for producing gems with attractive tonality and fine crystallographic quality. The overall dimensions and cut proportions make this gem suitable for a variety of settings where an elongated oval silhouette is desired, and the transparent body allows the cut geometry to remain a focal element of the gem appearance.

In terms of durability, sapphire is a corundum species and ranks 9 on the Mohs hardness scale, which places it among the hardest gem materials available after diamond, which is 10. Compared to common jewelry gems, this sapphire is significantly more resistant to abrasion than topaz at 8 and quartz at 7, making it an excellent choice for daily wear in rings and other frequently handled pieces. Hardness is one measure of wear resistance, and at Mohs 9 this stone will resist scratches from most materials encountered in ordinary use, while still requiring caution to avoid hard impacts and sharp blows that can cause chips or fractures. Given its very very slightly included clarity and absence of enhancement, routine cleaning by professional jewelers and careful handling in daily wear are recommended to preserve the polish and light performance.
