1.04 Ct. Yellowish Green Sapphire from Tanzania

This sapphire is a transparent, oval shaped natural corundum weighing 1.04 carats, with precise dimensions of 6.70 x 5.75 x 3.11 millimeters, and a mixed brilliant cut that balances table and pavilion facets to optimize light return. The color presents as a yellowish green with medium intensity, a tone that shows attractive saturation without overpowering brightness, and the overall finish is described as excellent polish, contributing to a clean, lively appearance. Clarity is graded as eye clean when evaluated at eye level, indicating an absence of inclusions visible to unaided vision, which supports a pleasing, uninterrupted visual field through the stone. The sapphire has not been subjected to any enhancement, it remains in its natural state, and its place of origin is Tanzania, a region known for producing a range of high quality sapphires. These objective specifications are provided to enable careful assessment of the gem for use in fine jewelry applications.

From a durability perspective this sapphire is well suited to daily wear, due to the inherent properties of corundum. Sapphires have a Mohs hardness of nine, making them second only to diamond in resistance to surface scratching among commonly used gem materials, which significantly reduces the likelihood of everyday abrasions from incidental contact. The gemstone’s toughness, or resistance to breakage, is also favorable for routine wear, provided it is set with consideration for potential impacts. The mixed brilliant cut and excellent polish enhance the stone’s ability to reflect light while maintaining smooth facet junctions that are less prone to microchipping under normal use, and the eye clean clarity grade places fewer internal weaknesses that could compromise structural integrity. Together these factors make the stone appropriate for rings, pendants, and other jewelry pieces intended for consistent wear.

Practical considerations for ensuring longevity of the sapphire in daily jewelry involve appropriate setting and routine maintenance. Protective settings, such as a close bezel or secure low-profile prongs, can shield the girdle and culet from direct knocks while still allowing the mixed brilliant cut to display strong brilliance. Regular inspection of prongs and setting shoulders by a qualified jeweler will address wear before it becomes problematic. Cleaning can be performed with mild soap and warm water and gentle brushing, and because this sapphire is natural and untreated, many common cleaning methods are acceptable; however, any stone should be inspected prior to ultrasonic or steam cleaning to confirm there are no structural features that would recommend against those methods. Avoid prolonged exposure to harsh chemicals and extreme thermal shock, and store the piece separately to prevent contact with harder stones, which further preserves the gem’s polished surfaces and precise facet boundaries.

The Natural Sapphire Company provides these measured details to assist in evaluating this Tanzanian yellowish green sapphire for incorporation into personally designed jewelry or for selection from finished pieces, and our gemological staff have evaluated the stone’s color, clarity, cut, and finish according to consistent standards. The absence of enhancement, combined with the stone’s eye clean clarity, medium color intensity, and excellent polish, results in a durable, attractive gem ready for everyday wear when set thoughtfully. Documentation of the gem’s weight, dimensions, cut, clarity assessment at eye level, polish quality, enhancement status, and origin accompanies the presentation of the stone, supporting informed decisions regarding design and care. This combination of physical robustness, natural state, and careful finishing makes the sapphire a reliable candidate for daily jewelry that balances aesthetic appeal with practical performance.
