Tanzanite is an exceedingly rare precious gemstone that is only found in the Usumburu Mountains that border the Umba Valley of northern Tanzania. It was 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). The piece comes complete with AIG (American International Gemologists, a GIA certified lab AIG Appraisal Number#: 000716266034) report and appraisal, confirming the above info and giving a total value of $102,550.00. GIA (Gemological Institute of America) Tanzanite Grading Report#: 5141971141
