A sweet, perfectly pink Umba sapphire from our Moyo Gems Collection. It was responsibly sourced from TAWOMA (the Tanzanian Womens Mining Association) member, Jumane, who mined the rough gemstone in Tanzania's Tanga region. The beautiful square cushion cut was faceted by Beth Stier in Michigan. While there is a small whitish inclusion in the corner of the crown, it is difficult to see with the naked eye, as are any additional inclusions within this Umba sapphire. This sapphire's color is so captivating, it masks it's imperfections. No heat. Untreated.
