A typical Umba Sapphire from Tanzania. These stones are unique in the range of colours shown, usually in the blue to purple range sometimes pink and green. The Sapphires not only show a strong dichroism - that is, they show two distinct colours - many, but not all, of the Umba Sapphires also show a strong to medium 'colour-change' depending whether they are observed in daylight or incandescent light. It is this phenomena which makes they extremely difficult to photograph as the camera usually shows the color-change in incandescent light.
