Iolite is the gem variety of Cordiertite. This mineral displays the strongest pleochroism seen in nature. Pleochroism is an optical phenomenon in which a mineral appears to be different colours when observed at different angles. This big 82 carat Iolite from Madagascar shows this typical dichroism (2 colours), from a nice deep blue to a transparent-light brown.
