Cushion-cut Umba Sapphire in a delicate mauve-lavender tone, sourced from the Umba Valley in northern Tanzania. This region is known for producing sapphires with unusual trace elements and visible silk, fingerprint, and needle-like inclusions that are often embraced rather than avoided — giving each stone a natural, untreated appearance and strong character. Collectors prize these inclusions for the insight they offer into the stone’s formation and authenticity
