0.66 Ct. Yellowish Green Sapphire from Tanzania

This is a beautiful transparent 0.66 carat pear shape yellowish green sapphire, measuring 7.15 by 4.42 by 2.85 millimeters, cut in a mixed brilliant style with an excellent polish. The mixed brilliant cut combines the scintillation and fire of brilliant facets with the elegant outline and light return of a pavilion that balances depth and spread, making the 0.66 carat weight read larger at face up than its modest carat number might suggest. Clarity is graded very very slightly included, evaluated at eye level, which to a trained buyer means the stone is effectively eye clean under normal viewing conditions, with only minor internal characteristics that do not detract from transparency or brilliance. Color intensity is medium, showing a refined yellowish green hue that sits between the more common yellow sapphires and rarer green tones, giving it a versatile and sophisticated appearance for both classic and contemporary settings. The sapphire is natural and untreated, with no enhancement, and is of Tanzanian origin, a provenance that collectors recognize for producing unique and attractive tones in the green to yellow spectrum.

From the perspective of an educated buyer, the 0.66 carat weight here represents premium quality rather than mere size, because the value equation for sapphires is driven by a combination of color, clarity, cut, and treatment status. An untreated, eye level very very slightly included sapphire with excellent polish and a well executed mixed brilliant pear cut commands a premium because it offers natural, durable beauty without the common color diffusion or heat treatments that alter value. The Tanzanian origin further enhances desirability for collectors seeking geographic diversity and distinct regional character. Practically, the dimensions and depth profile make this stone ideal for a center in a delicate engagement ring, or for a refined pendant where the pear outline emphasizes elegance and elongation. At 0.66 carats the piece is substantial enough to provide visual presence while remaining versatile for refined jewelry design. The Natural Sapphire Company offers this sapphire with the assurance that its documented clarity, natural origin, and absent enhancements elevate its market standing, making it a sound choice for discriminating buyers who prioritize natural provenance, excellent cutting, and authentic, attractive color in a premium gem.
