Iolite
The name 'Iolite' originates from the Greek word 'ios' meaning 'violet'. Iolite's exhibits strong pleochroism, which means that the stone appears to be different colors when observed at different angles. From one direction, Iolite can appear sapphire-like blue; from another, it can appear as clear as water. Furthermore, from the top view down, it can appear light golden or honey-yellow in color. It's considered to be a stone of vision, enhancing creative expression. Many believe that it can help recover lost memories and also help induce sleep for those who suffer from insomnia. Iolite is often available in very large cuts, with many stones weighing 5 carats or more. Because of larger cuts being readily available, Iolite gems make for excellent fashion jewelry and bold designs.
