7.86ct Bi-color Nigerian Sapphire Cushion
A true show-stopper! This Nigerian bi-color sapphire is a masterpiece of natural beauty. The 11mm step-cut square cushion reveals a stunning array of greens and yellows, with a striking teal hue that emerges as you move the stone. Its medium-toned colors include subtle blue zoning that contributes to its bi-color effect, though the zoning lines are not visible without a loupe. This gem is completely untreated, loupe clean, and weighs an impressive 7.86 carats. Given its size and unique color, it is an exceptionally rare gemstone, even among our extensive collection of Nigerian sapphires.
