Unheated Umba Sapphire in a muted steel blue, rectangular cushion cut to emphasize both color depth and transparency. Known for their mineral inclusions and fingerprint-like structures, Umba Valley sapphires often carry a geological narrative visible under magnification. This stone’s mix of internal characteristics and smoky undertones is classic for the deposit—less commercial, more natural, and unmistakably East African
