About This Stone

This 7.14 carat loose sapphire comes from the Umba River in Tanzania and shows a distinctive color change from earthy teal blue green to earthy peach. The custom geometric oval cut gives the stone a bold outline while allowing the shifting color to read clearly as it moves through different light. Umba sapphires are known for their unusual natural color and individual character, and this stone has both strong size and a rare palette that makes it especially memorable.

Its scale and shape make it especially well suited for a substantial custom ring or pendant necklace, as well as a one-of-a-kind collector piece. This natural unheated sapphire would appeal to someone looking for a loose Tanzania sapphire with color change, strong presence, and an uncommon cut.
