1.91 carat natural sapphire from Umba, Tanzania showing a vivid, stable medium blue in all lighting conditions, without the color change commonly seen from this locality. The color remains consistent and saturated rather than shifting toward purple or gray.
Untreated. While Umba sapphires often display noticeable color change, this stone presents an unusually clean and stable blue appearance more typically associated with classic sapphire sources. Minor inclusions may be present, consistent with untreated material, and do not detract from overall visual performance.
Cut in a custom modified oval design to suit the rough, with strong brightness and balanced proportions.
