Most iolite is found in gravel beds in the form of water-worn pebbles. Due to pleochroism or dichroism phenomena, iolite displays different colors when viewed from different angles. Iolite can appear almost clear in one orientation, then present a deep purple color in another orientation. Because iolite typically has very few inclusions, it is ideal for faceting and displays clear, bright color. The hexagon is cut is a modified brilliant featuring large facets and step cuts along the six equal sides of the girdle.
