Tanzanite Is a very rare precious gemstone that is only found in the Usumburu Mountains that border the Umba Valley of northern Tanzania. Originally discovered in 1967 by Tiffany & Company who named the stone Tanzanite. This example is unique due to its exceptional pleochroism (an optical phenomenon in which a stone has different colors when observed at different angles).
