2.17 Ct. Color Change Sapphire from Tanzania

This specimen is a transparent 2.17 carat oval shape color change sapphire with dimensions of 8.43 by 6.31 by 4.72 mm, presented with a mixed brilliant cut that balances a faceted crown with a pavilion designed for maximum light performance. The clarity grade is very slightly included evaluated at eye level, indicating minimal internal features that do not materially affect the gem s overall appearance or brilliance. Color intensity is vivid, and the stone exhibits a notable color change phenomenon that is visible under differing lighting conditions, a characteristic prized for its rarity and visual interest. The polish on this sapphire is graded excellent, providing crisp facet junctions and a reflective surface that enhances the stone s luster and optical return. There has been no enhancement applied to this sapphire, it is in its natural state, and the origin is Tanzania, a source known for producing sapphires with strong saturation and fine crystalline structure. These objective characteristics together define the gem s aesthetic and technical profile, providing a clear basis for assessment and setting decisions.

From a durability perspective this sapphire is exceptionally well suited to daily wear, owing to the inherent properties of corundum combined with the gem s specific condition and craftsmanship. Sapphire ranks nine on the Mohs scale of mineral hardness, which places it just below diamond and makes it highly resistant to scratching from ordinary wear and contact with most materials encountered in everyday life. Corundum also lacks true cleavage planes, so it is not prone to splitting along defined directions, and it typically exhibits good toughness which reduces the risk of chipping under normal use. The very slightly included clarity means there are few internal stress points that could compromise structural integrity, and the excellent polish reduces the likelihood of surface impairments that might propagate into fractures. The mixed brilliant cut also contributes to durability because the cut proportions distribute stress across multiple facets rather than concentrating it at a single vulnerable point. The fact that the sapphire is unenhanced is also relevant to long term stability, because there are no introduced fracture filling materials or diffusion treatments that might alter how the stone responds to heat, chemical exposure, or rigorous cleaning methods.

Practical considerations for daily wear include appropriate setting choices and basic care practices, both of which are straightforward for this sapphire. For rings and bracelets where impact risk is greater, settings that offer protective metal around the girdle such as bezels or well designed prong arrangements with adequately sized prongs are recommended to shield the stone from direct knocks. For pendants and earrings, where the stone is less likely to be struck, the sapphire s hardness and clarity allow for more open settings that showcase the color change and brilliance. Cleaning can be done with warm water, mild dish soap, and a soft brush, which is effective and safe for natural untreated corundum. Ultrasonic and steam cleaning are generally safe for sapphires that are free of fracture filling or other enhancements, however caution is advised if the setting is loose, and professional inspection of the mounting is recommended periodically. With routine care and sensible setting choices this Tanzanian color change sapphire will retain its visual appeal and structural integrity over decades, making it an excellent candidate for an everyday jewelry piece that can also function as an heirloom.

The Natural Sapphire Company offers this 2.17 carat oval color change sapphire as a well documented example of natural corundum that combines visual distinction with robust physical properties that favor daily wear. Its vivid color change, very slightly included clarity at eye level, excellent polish, and absence of enhancements provide a transparent basis for assessing both beauty and longevity. The Tanzanian origin adds a provenance component that may be important to collectors and those who value geological background. Whether set for an engagement ring, a daily wear pendant, or a versatile pair of earrings, this sapphire s technical attributes and intrinsic durability make it a practical and enduring choice for jewelry intended for regular use.
