The term Royal Blue is reserved for the most illustrious sapphires. This color term can only be applied to sapphires that exhibit exceptional color within a very specific range of medium to moderately deep tone together with a vivid saturation. These stones must not have undergone any enhancement through heat treatment as well. The present lot combines this coveted color with the most prestigious sapphire origin, Kashmir, in a large gem in excess of 16 carats. It is a remarkable example suitable for the most discerning collectors.
