1.57 Ct. Bi Color Sapphire from Tanzania

This 1.57 carat cushion shape bi color sapphire from Tanzania is a compelling alternative to the usual engagement gem, offering an immediate visual distinction and lasting value. Measuring 6.98 x 4.94 x 4.82 mm, with a mixed brilliant cut and excellent polish, it delivers lively scintillation and depth that many standard cuts fail to achieve, the mixed brilliant facets maximize light return for a lively face up appearance while the cushion outline gives a classic romantic silhouette. The stone is transparent, with a clarity grade of very slightly included evaluated at eye level, meaning the inclusions do not disrupt the gem's beauty to the naked eye and in many settings will remain effectively eye clean, a quality that places it above many commercial sapphires that are heavily included or rely on treatments to improve appearance. Uniquely this sapphire has no enhancement, a rarity compared to the majority of heated or treated sapphires on the market, and its medium intense color intensity produces a balanced, wearable palette that shifts subtly between tones, giving the gem personality without overpowering the design.
