Origin & Supply of Iolite
Iolite played an important part in history. The Norse explorer Leif Ericson used thin pieces of iolite as the world's first polarizing filter. Due to its strong pleochroism, he was able to use iolite as a lens, so he could work out the exact position of the sun and navigate to safety. Iolite gemstones are found across the world including Sri Lanka, India, Namibia, Brazil, Tanzania, Madagascar, Connecticut and Canada.
While iolite is the term used in the gemmology industry, cordierite is actually its correct mineralogy classification. Iolite is a magnesium ion aluminium cyclosilicate, which almost always contains iron.
