This beautiful purple Umba sapphire is from our Moyo Gems Collection and was responsibly sourced from TAWOMA (Tanzanian Womens Mining Association) member, Mwanaidi, who mined the rough gemstone in Tanzania's Tanga region. The hexagon cut was faceted by Beth Stier in Michigan. This sapphire is a true Umba with many manu color variations (flashes of blue, gold, pink), rutiles, and inclusions. It is not eye clean, rather full of unique color and life. No heat. Untreated.
