1.66 Ct. Blue Sapphire from Tanzania

This transparent 1.66 carat oval shape blue sapphire measures 6.87 x 5.94 x 4.95 mm, and is cut in a mixed brilliant style to balance color depth and light performance. Its clarity grade is very slightly included when evaluated at eye level, which means the stone appears clean to the unaided eye while retaining natural character under magnification. The color intensity is described as intense, offering a rich blue that shows depth without appearing overly dark, and the gemstone displays an excellent polish that enhances surface luster and facet brilliance. This sapphire is natural and untreated, no enhancement, and originates from Tanzania, a source known for producing sapphires with lively color and good clarity. The combination of mixed brilliant faceting and precise proportions allows this stone to return light with a lively scintillation that complements its saturated hue, making the optical performance appealing in both direct and diffused lighting.

For the educated buyer, this stone represents value through its balance of quality factors, provenance, and condition. The very slightly included clarity grade supports a strong visual appeal while also serving as an indicator of natural formation, and the absence of heat or other enhancements preserves the stone in its original state which commands a premium in the market. At 1.66 carats the sapphire is a versatile size, suitable for a variety of jewelry designs, and the oval outline is particularly adaptable to rings, pendants, and earrings, fitting both casual and formal settings. In an everyday setting the modest depth and bright polish offer sparkle and durable wearability, while in a formal setting the intense blue and refined cut project sophistication and presence. The Natural Sapphire Company presents this gem with careful documentation of its measurements, cut, clarity, and origin, allowing knowledgeable buyers to assess its rarity and investment potential. If you seek a natural Tanzanian sapphire that combines attractive color, honest clarity, and classic versatility, this 1.66 carat oval sapphire is an excellent candidate for a bespoke setting that will perform beautifully across occasions.
