This 1.38 carat loose sapphire comes from the Umba River in Tanzania and shows a distinctive mix of violet and denim blue. The custom trillion cut gives the stone a sharp, modern outline while allowing the color to shift softly as it moves through different light. Umba sapphires are known for their natural range of color and character, and this stone has a clean, balanced look with a more unusual palette.
Its size and shape make it well suited for a custom ring, pendant necklace, or other one-of-a-kind fine jewelry design. This natural loose sapphire would be a strong choice for someone looking for a Tanzania sapphire with violet blue color and a distinctive trillion cut.
